      About a year ago I acquired the 4S mill. I attempted to get it running off the original software, but its not working at all. I started reading about a conversion to Mach 3 and I'm very interested in the retrofit process. I was wondering if there were any write ups or pictures out there of previous retrofits?

              The D&M4 is about as easy a "kit " as you're going to get. All you'll need is a break out board and a win XP machine with a parallel port. A couple hours to wire it. May be 5-6 if you really want do do it pretty. That's about as cheap as it gets. We used one of BOB Cambells boards who gave great support. It all depends on how comfortable you feel with wiring. I'm out there at the crazy extreme with some of the machines I did with just the 25 pin cord I wacked wired and got on down the road. It works but it's not for everybody. OTOH I fix radio stations for a living ( I.E. more knowledge than patience) and if you don't do electronics for a living then really you should be using a break out board. In reality there's lots of safety reasons to use a break out board. Back to the first rule of physics. Just because you can doesn't mean you should. Getting a gecko G540 is about the only way to make it any easier. New drivers and BOB all in one for ~$250 if you shop around. Not to mention the Gecko Group is on par with this one for finding help. I got it going on the stock control first. You may or may not be able to do this. OTOH I suggest not wasting your time with an old 386 unless you really feel the need to get your geek on. You'll need a PC with a parallel port to run Mach3. Or A smooth stepper if you have to use win7 on USB. I think Galli? also make s a board that speaks USB. Another place you might ask for help is the DIY-CNC group. IIRC " OLD BOB " also did a D&M4 conversion. Don't be intimidated by the wiring side. It's pretty straight forward. Easy to trouble shoot. You'll find plenty of help. You can start by gutting out the old 386. Hold on to the power supply. you might want it later for +5V supply. When you get ready to load up Mach DO watch the video. It's 20 min well spent and it will save you a lot of time in your setup. Rob

              I haven't had much luck finding write ups on the retrofit. It seems that it was being sent through email. I tried private messaging a few people, but I don't think they visit CNCzone anymore.

                Thank you for the information :). I am just getting back to my project. I tried searching for posts on cnczone.com and the only thing that comes up is a D&M mill documentation thread. Seems like nobody really found a solution there. Would there be any tutorials? From what I gathered I can wire up the motors directly into the Gecko g540 and eliminate the motor boards? The 37 volt power supply could stay, but all of the floppy disk hardware should be easy enough to remove.

                Thanks again,

                Alex

                  Yeah you can pretty much gut all the PC hardware, driver boards( although they are a nice version the LM18200 2.5 A stepper driver ) and power supplies. the back plane makes for easy service and easy mounting for the power supply and the G540. My buddy who did the final upgrade took out the front control panel and put speed and power switches in it's place. A G-540 is about as easy as it gets! Granted soldering the DB9 connectors takes a bit of skill but that is the worst of it. I don't remember the color codes for the stock steppers. Usually they are pretty weak as the magnets degrade over time. The original stepper on the Z axis was having trouble not losing steps. There are tutorials that describe how to use an ohm meter to figure out which wires are pairs. Once you do that It's pretty easy. There's also tons of help available on the gecko site. The manual is pretty easy to follow. Good steppers are cheap these days! You may want to upgrade the power supply if you do. The voltage regulator ( LM 317 ) on the stock power supply is only rated for 1.5A IIRC it was putting out ~37V. When we up graded the steppers and installed the g 540 I think we used a 5A, 48V supply.If you want I can hook you up with my friend who actually did most of the upgrades. I think there's another fellow on that list that goes by IIRC "Old BOB" that has done the same modification as well. Rob

                  Thank you for the information :). I am just getting back to my project. I tried searching for posts on cnczone.com and the only thing that comes up is a D&M mill documentation thread. Seems like nobody really found a solution there. Would there be any tutorials? From what I gathered I can wire up the motors directly into the Gecko g540 and eliminate the motor boards? The 37 volt power supply could stay, but all of the floppy disk hardware should be easy enough to remove.



                  Thanks again,



                  Alex

It's been a while but I think there was a thread on cnc Zone.Cliff's notes version.You strip out all the old PC parts.On the stepper boards there's -,+,clock,DIR. The machine has a ~37V power supply. You run power to the +/- and step pulses go to the clock pin. Dir to the Dir pin. It's a pretty easy mod. That's enough to get you going. It's even better if you use G540 and replace the drivers. There's also a good chance the steppers are tired and you'll eventually want to replace those. Sure line is a good source for parts. A to Z cnc also makes some nice retrofit mounts. I thought it was a pretty decent machine to learn on. I've since moved on. Rob To: mach1mach2cnc@yahoogroups.com

The manual is pretty easy to follow. Good steppers are cheap these days! You may want to upgrade the power supply if you do. The voltage regulator ( LM 317 ) on the stock power supply is only rated for 1.5A IIRC it was putting out ~37V. When we up graded the steppers and installed the g 540 I think we used a 5A, 48V supply.If you want I can hook you up with my friend who actually did most of the upgrades. I think there's another fellow on that list that goes by IIRC "Old BOB" that has done the same modification as well. Rob

I tried searching for posts on cnczone.com and the only thing that comes up is a D&M mill documentation thread. Seems like nobody really found a solution there. Would there be any tutorials? From what I gathered I can wire up the motors directly into the Gecko g540 and eliminate the motor boards? The 37 volt power supply could stay, but all of the floppy disk hardware should be easy enough to remove.

It's been a while but I think there was a thread on cnc Zone.Cliff's notes version.You strip out all the old PC parts.On the stepper boards there's -,+,clock,DIR. The machine has a ~37V power supply. You run power to the +/- and step pulses go to the clock pin. Dir to the Dir pin. It's a pretty easy mod. That's enough to get you going. It's even better if you use G540 and replace the drivers. There's also a good chance the steppers are tired and you'll eventually want to replace those. Sure line is a good source for parts. A to Z cnc also makes some nice retrofit mounts. I thought it was a pretty decent machine to learn on. I've since moved on. Rob To: mach1mach2cnc@yahoogroups.com

I started reading about a conversion to Mach 3 and I'm very interested in the retrofit process. I was wondering if there were any write ups or pictures out there of previous retrofits?

                        I've been putting together a shopping list for the machine. http://www.kelinginc.net/GeckorDriver.html seems to be a cost effective website. Has anyone ordered from them before? I am looking at the gecko g540, 48v power supply, and new stepper motors. Should I go with the 48V 7.3A or 12.5A power supply? I did talk to another vendor and the 7.3A should be plenty, but I just want to make sure. Also, kelinginc offers NEMA motors. I am slightly baffled with which motor I should go with for my x,y, and z. Any input would be greatly appreciated. Thanks again, Alex

My buddy who did the final upgrade took out the front control panel and put speed and power switches in it's place. A G-540 is about as easy as it gets! Granted soldering the DB9 connectors takes a bit of skill but that is the worst of it. I don't remember the color codes for the stock steppers.

I tried searching for posts on cnczone.com and the only thing that comes up is a D&M mill documentation thread. Seems like nobody really found a solution there. Would there be any tutorials? From what I gathered I can wire up the motors directly into the Gecko g540 and eliminate the motor boards? The 37 volt power supply could stay, but all of the floppy disk hardware should be easy enough to remove.

It's been a while but I think there was a thread on cnc Zone.Cliff's notes version.You strip out all the old PC parts.On the stepper boards there's -,+,clock,DIR. The machine has a ~37V power supply. You run power to the +/- and step pulses go to the clock pin. Dir to the Dir pin. It's a pretty easy mod. That's enough to get you going. It's even better if you use G540 and replace the drivers. There's also a good chance the steppers are tired and you'll eventually want to replace those. Sure line is a good source for parts. A to Z cnc also makes some nice retrofit mounts. I thought it was a pretty decent machine to learn on. I've since moved on. Rob To: mach1mach2cnc@yahoogroups.com

I started reading about a conversion to Mach 3 and I'm very interested in the retrofit process. I was wondering if there were any write ups or pictures out there of previous retrofits?

                          Alex,

                          I buy all my motors from Rick at www.homeshopcnc.com. I checked with
                          Amazon.com yesterday and they had a 48 volt power supply for about $39.00. I
                          plan to buy four of them today.

                          I've been putting together a shopping list for the machine.
                          http://www.kelinginc.net/GeckorDriver.html seems to be a cost effective
                          website. Has anyone ordered from them before? I am looking at the gecko
                          g540, 48v power supply, and new stepper motors. Should I go with the 48V
                          7.3A or 12.5A power supply? I did talk to another vendor and the 7.3A
                          should be plenty, but I just want to make sure. Also, kelinginc offers
                          NEMA motors. I am slightly baffled with which motor I should go with for my
                          x,y, and z. Any input would be greatly appreciated. Thanks again, Alex

                          although they are a nice version the LM18200 2.5 A stepper driver ) and
                          power supplies. the back plane makes for easy service and easy mounting for
                          the power supply and the G540. My buddy who did the final upgrade took out
                          the front control panel and put speed and power switches in it's place. A
                          G-540 is about as easy as it gets! Granted soldering the DB9 connectors
                          takes a bit of skill but that is the worst of it. I don't remember the color
                          codes for the stock steppers. Usually they are pretty weak as the magnets
                          degrade over time. The original stepper on the Z axis was having trouble
                          not losing steps. There are tutorials that describe how to use an ohm
                          meter to figure out which wires are pairs. Once you do that It's pretty
                          easy. There's also tons of help available on the gecko site. The manual
                          is pretty easy to follow. Good steppers are cheap these days! You may want
                          to upgrade the power supply if you do. The voltage regulator ( LM 317 ) on
                          the stock power supply is only rated for 1.5A IIRC it was putting out
                          ~37V. When we up graded the steppers and installed the g 540 I think we
                          used a 5A, 48V supply.If you want I can hook you up with my friend who
                          actually did most of the upgrades. I think there's another fellow on that
                          list that goes by IIRC "Old BOB" that has done the same modification as
                          well. Rob

                          project. I tried searching for posts on cnczone.com and the only thing that
                          comes up is a D&M mill documentation thread. Seems like nobody really found
                          a solution there. Would there be any tutorials? From what I gathered I can
                          wire up the motors directly into the Gecko g540 and eliminate the motor
                          boards? The 37 volt power supply could stay, but all of the floppy disk
                          hardware should be easy enough to remove.

                          easy. It's been a while but I think there was a thread on cnc Zone.Cliff's
                          notes version.You strip out all the old PC parts.On the stepper boards
                          there's -,+,clock,DIR. The machine has a ~37V power supply. You run power
                          to the +/- and step pulses go to the clock pin. Dir to the Dir pin. It's a
                          pretty easy mod. That's enough to get you going. It's even better if you
                          use G540 and replace the drivers. There's also a good chance the steppers
                          are tired and you'll eventually want to replace those. Sure line is a good
                          source for parts. A to Z cnc also makes some nice retrofit mounts. I
                          thought it was a pretty decent machine to learn on. I've since moved on.

                          running off the original software, but its not working at all. I started
                          reading about a conversion to Mach 3 and I'm very interested in the retrofit
                          process. I was wondering if there were any write ups or pictures out there
                          of previous retrofits?

Has anyone ordered from them before? I am looking at the gecko g540, 48v power supply, and new stepper motors. Should I go with the 48V 7.3A or 12.5A power supply? I did talk to another vendor and the 7.3A should be plenty, but I just want to make sure. Also, kelinginc offers NEMA motors. I am slightly baffled with which motor I should go with for my x,y, and z. Any input would be greatly appreciated. Thanks again, Alex

                              I've lost track of the number of stepper motors and drives purchased
                              from them directly and via other companies that I work with.

                              They have always been responsive to any problems. It is a good,
                              reliable company and they have a lot in stock.

                                Power supply will depend on the motors. OTOH you might want to condisder getting a power supply to match what the G540 is capable of or larger. A bigger supply won't get as hot for it's given load so it will tend to last longer. Head room is always a good thing. IIRC the G540 has a ~ 7A fuse but I'd look that up to be sure. It's been awhile.

My buddy who did the final upgrade took out the front control panel and put speed and power switches in it's place. A G-540 is about as easy as it gets! Granted soldering the DB9 connectors takes a bit of skill but that is the worst of it. I don't remember the color codes for the stock steppers. Usually they are pretty weak as the magnets degrade over time. The original stepper on the Z axis was having trouble not losing steps. There are tutorials that describe how to use an ohm meter to figure out which wires are pairs. Once you do that It's pretty easy. There's also tons of help available on the gecko site. The manual is pretty easy to follow. Good steppers are cheap these days! You may want to upgrade the power supply if you do. The voltage regulator ( LM 317 ) on the stock power supply is only rated for 1.5A IIRC it was putting out ~37V. When we up graded the steppers and installed the g 540 I think we used a 5A, 48V supply.If you want I can hook you up with my friend who actually did most of the upgrades. I think there's another fellow on that list that goes by IIRC "Old BOB" that has done the same modification as well. Rob

I tried searching for posts on cnczone.com and the only thing that comes up is a D&M mill documentation thread. Seems like nobody really found a solution there. Would there be any tutorials? From what I gathered I can wire up the motors directly into the Gecko g540 and eliminate the motor boards? The 37 volt power supply could stay, but all of the floppy disk hardware should be easy enough to remove.

It's been a while but I think there was a thread on cnc Zone.Cliff's notes version.You strip out all the old PC parts.On the stepper boards there's -,+,clock,DIR. The machine has a ~37V power supply. You run power to the +/- and step pulses go to the clock pin. Dir to the Dir pin. It's a pretty easy mod. That's enough to get you going. It's even better if you use G540 and replace the drivers. There's also a good chance the steppers are tired and you'll eventually want to replace those. Sure line is a good source for parts. A to Z cnc also makes some nice retrofit mounts. I thought it was a pretty decent machine to learn on. I've since moved on. Rob To: mach1mach2cnc@yahoogroups.com

I started reading about a conversion to Mach 3 and I'm very interested in the retrofit process. I was wondering if there were any write ups or pictures out there of previous retrofits?

                                Thanks again for the referrals :). I am trying to decide on some motors. The NEMA 23 seems to be the way to go, but I am confused with what OZ I should go

                                  Thanks again for the referrals :). I am trying to decide on some motors. The NEMA 23 seems to be the way to go, but I am confused with what OZ I should go with. I can't say I am knowledgeable on that subject. I am looking at the line up on http://www.automationtechnologiesinc.com/products-page/nema-23

                                    I have some new and very lightly used Nema 34(3) & 23(2) steppers and 2 digital drives by Keling I would like to sell. I upgraded to AC servo but all the old stuff worked great. Bought some from Automation Technologies, Anaheim Auto and CNC4PC.
                                     
                                    Get in touch if yourself or any other interested parties. Will cut a deal. If this is wrongly placed sorry for that.
                                     
                                    Regarding the DC power, I like Antek out of Jersey a bit more money but looks nice and beefy. Using it now...perfect, 500 watt. Can get it with optional 5V for logic too.

                                    I've been putting together a shopping list for the machine. http://www.kelinginc.net/GeckorDriver.html seems to be a cost effective website. Has anyone ordered from them before? I am looking at the gecko g540, 48v power supply, and new stepper motors. Should I go with the 48V 7.3A or 12.5A power supply? I did talk to another vendor and the 7.3A should be plenty, but I just want to make sure. Also, kelinginc offers NEMA motors. I am slightly baffled with which motor I should go with for my x,y, and z. Any input would be greatly appreciated. Thanks again, Alex

My buddy who did the final upgrade took out the front control panel and put speed and power switches in it's place. A G-540 is about as easy as it gets! Granted soldering the DB9 connectors takes a bit of skill but that is the worst of it. I don't remember the color codes for the stock steppers. Usually they are pretty weak as the magnets degrade over time. The original stepper on the Z axis was having trouble not losing steps. There are tutorials that describe how to use an ohm meter to figure out which wires are pairs. Once you do that It's pretty easy. There's also tons of help available on the gecko site. The manual is pretty easy to follow. Good steppers are cheap these days! You may want to upgrade the
                                    power supply if you do. The voltage regulator ( LM 317 ) on the stock power supply is only rated for 1.5A IIRC it was putting out ~37V. When we up graded the steppers and installed the g 540 I think we used a 5A, 48V supply.If you want I can hook you up with my friend who actually did most of the upgrades. I think there's another fellow on that list that goes by IIRC "Old BOB" that has done the same modification as well. Rob

I tried searching for posts on cnczone.com and the only thing that comes up is a D&M mill documentation thread. Seems like nobody really found a solution there. Would there be any tutorials? From what I gathered I can wire up the motors directly into the Gecko g540 and eliminate the motor boards? The 37 volt power supply could stay, but all of the floppy disk hardware should be easy enough to remove.

It's been a while but I think there was a thread on cnc Zone.Cliff's notes version.You strip out all the old PC parts.On the stepper boards there's -,+,clock,DIR. The machine has a ~37V power supply. You run power to the +/- and step pulses go to the clock pin. Dir to the Dir pin. It's a pretty easy mod. That's enough to get you going. It's even better if you use G540 and replace the drivers. There's also a good chance the steppers are tired and you'll eventually want to replace those. Sure line is a good source for parts. A to Z cnc also makes some nice retrofit mounts. I thought it was a pretty decent machine to learn on. I've since moved on. Rob To: mach1mach2cnc@yahoogroups.com

                                    I believe I have made some progress sorting through the Sherline mill set up online. From what I gathered they are running a Nema 23 1/4 inch shaft motor.

                                      I believe I have made some progress sorting through the Sherline mill set up online. From what I gathered they are running a Nema 23 1/4 inch shaft motor. The kit they offer has 135oz motors. Since the 23 is factory I was thinking about purchasing a Nema23 425 oz. I did purchase a 48 volt 7.3A 350 Watt power supply. From what I found this power supply can run 4 stepper motors at 3.5 amps.

                                      Since my D&M mill is a Sherline I should be able to bolt up a Nema23 with a higher oz rating.

                                      The factory set up uses some sort of coupler/sleeve to connect the motor to the axis. Does this info sound realistic? Still working through my learning curve.

Has anyone ordered from them before? I am looking at the gecko g540, 48v power supply, and new stepper motors. Should I go with the 48V 7.3A or 12.5A power supply? I did talk to another vendor and the 7.3A should be plenty, but I just want to make sure. Also, kelinginc offers NEMA motors. I am slightly baffled with which motor I should go with for my x,y, and z. Any input would be greatly appreciated. Thanks again, Alex

My buddy who did the final upgrade took out the front control panel and put speed and power switches in it's place. A G-540 is about as easy as it gets! Granted soldering the DB9 connectors takes a bit of skill but that is the worst of it. I don't remember the color codes for the stock steppers. Usually they are pretty weak as the magnets degrade over time. The original stepper on the Z axis was having trouble not losing steps. There are tutorials that describe how to use an ohm meter to figure out which wires are pairs. Once you do that It's pretty easy. There's also tons of help available on the gecko site. The manual is pretty easy to follow. Good steppers are cheap these days! You may want to upgrade the

When we up graded the steppers and installed the g 540 I think we used a 5A, 48V supply.If you want I can hook you up with my friend who actually did most of the upgrades. I think there's another fellow on that list that goes by IIRC "Old BOB" that has done the same modification as well. Rob

I tried searching for posts on cnczone.com and the only thing that comes up is a D&M mill documentation thread. Seems like nobody really found a solution there. Would there be any tutorials? From what I gathered I can wire up the motors directly into the Gecko g540 and eliminate the motor boards? The 37 volt power supply could stay, but all of the floppy disk hardware should be easy enough to remove.

It's been a while but I think there was a thread on cnc Zone.Cliff's notes version.You strip out all the old PC parts.On the stepper boards there's -,+,clock,DIR. The machine has a ~37V power supply. You run power to the +/- and step pulses go to the clock pin. Dir to the Dir pin. It's a pretty easy mod. That's enough to get you going. It's even better if you use G540 and replace the drivers. There's also a good chance the steppers are tired and you'll eventually want to replace those. Sure line is a good source for parts. A to Z cnc also makes some nice retrofit mounts. I thought it was a pretty decent machine to learn on. I've since moved on. Rob To: mach1mach2cnc@yahoogroups.com

I started reading about a conversion to Mach 3 and I'm very interested in the retrofit process. I was wondering if there were any write ups or pictures out there of previous retrofits?

                                      Is the 425 a double stack? having that much mass on the end of the table can cause it s own problems. Rob To: mach1mach2cnc@yahoogroups.com From:

                                        I believe I have made some progress sorting through the Sherline mill set up online. From what I gathered they are running a Nema 23 1/4 inch shaft motor. The kit they offer has 135oz motors. Since the 23 is factory I was thinking about purchasing a Nema23 425 oz. I did purchase a 48 volt 7.3A 350 Watt power supply. From what I found this power supply can run 4 stepper motors at 3.5 amps.



                                        Since my D&M mill is a Sherline I should be able to bolt up a Nema23 with a higher oz rating.



                                        The factory set up uses some sort of coupler/sleeve to connect the motor to the axis. Does this info sound realistic? Still working through my learning curve.

Has anyone ordered from them before? I am looking at the gecko g540, 48v power supply, and new stepper motors. Should I go with the 48V 7.3A or 12.5A power supply? I did talk to another vendor and the 7.3A should be plenty, but I just want to make sure. Also, kelinginc offers NEMA motors. I am slightly baffled with which motor I should go with for my x,y, and z. Any input would be greatly appreciated. Thanks again, Alex

My buddy who did the final upgrade took out the front control panel and put speed and power switches in it's place. A G-540 is about as easy as it gets! Granted soldering the DB9 connectors takes a bit of skill but that is the worst of it. I don't remember the color codes for the stock steppers. Usually they are pretty weak as the magnets degrade over time. The original stepper on the Z axis was having trouble not losing steps. There are tutorials that describe how to use an ohm meter to figure out which wires are pairs. Once you do that It's pretty easy. There's also tons of help available on the gecko site. The manual is pretty easy to follow. Good steppers are cheap these days! You may want to upgrade the

When we up graded the steppers and installed the g 540 I think we used a 5A, 48V supply.If you want I can hook you up with my friend who actually did most of the upgrades. I think there's another fellow on that list that goes by IIRC "Old BOB" that has done the same modification as well. Rob

I tried searching for posts on cnczone.com and the only thing that comes up is a D&M mill documentation thread. Seems like nobody really found a solution there. Would there be any tutorials? From what I gathered I can wire up the motors directly into the Gecko g540 and eliminate the motor boards? The 37 volt power supply could stay, but all of the floppy disk hardware should be easy enough to remove.

It's been a while but I think there was a thread on cnc Zone.Cliff's notes version.You strip out all the old PC parts.On the stepper boards there's -,+,clock,DIR. The machine has a ~37V power supply. You run power to the +/- and step pulses go to the clock pin. Dir to the Dir pin. It's a pretty easy mod. That's enough to get you going. It's even better if you use G540 and replace the drivers. There's also a good chance the steppers are tired and you'll eventually want to replace those. Sure line is a good source for parts. A to Z cnc also makes some nice retrofit mounts. I thought it was a pretty decent machine to learn on. I've since moved on. Rob To: mach1mach2cnc@yahoogroups.com

                                          I think I was getting ahead of myself after I looked around some more. I found a site mentioning: The 425's are more powerful than what a Sherline CNC machine requires, and are not recommended for use on a Sherline. The rated torque from these motors is twice that of the commonly suggested rating for a Taig CNC machine. You should probably stick with the 269's for a Taig type machine as well.

                                          I found this on http://www.xylotex.com/425ozin.htm I am not familiar with the company, but I have seen the name around before. The 269 route looks like my best option.

The kit they offer has 135oz motors. Since the 23 is factory I was thinking about purchasing a Nema23 425 oz. I did purchase a 48 volt 7.3A 350 Watt power supply. From what I found this power supply can run 4 stepper motors at 3.5 amps.

Has anyone ordered from them before? I am looking at the gecko g540, 48v power supply, and new stepper motors. Should I go with the 48V 7.3A or 12.5A power supply? I did talk to another vendor and the 7.3A should be plenty, but I just want to make sure. Also, kelinginc offers NEMA motors. I am slightly baffled with which motor I should go with for my x,y, and z. Any input would be greatly appreciated. Thanks again, Alex

My buddy who did the final upgrade took out the front control panel and put speed and power switches in it's place. A G-540 is about as easy as it gets! Granted soldering the DB9 connectors takes a bit of skill but that is the worst of it. I don't remember the color codes for the stock steppers. Usually they are pretty weak as the magnets degrade over time. The original stepper on the Z axis was having trouble not losing steps. There are tutorials that describe how to use an ohm meter to figure out which wires are pairs. Once you do that It's pretty easy. There's also tons of help available on the gecko site. The manual is pretty easy to follow. Good steppers are cheap these days! You may want to upgrade the

When we up graded the steppers and installed the g 540 I think we used a 5A, 48V supply.If you want I can hook you up with my friend who actually did most of the upgrades. I think there's another fellow on that list that goes by IIRC "Old BOB" that has done the same modification as well. Rob

I tried searching for posts on cnczone.com and the only thing that comes up is a D&M mill documentation thread. Seems like nobody really found a solution there. Would there be any tutorials?

The 37 volt power supply could stay, but all of the floppy disk hardware should be easy enough to remove.

It's been a while but I think there was a thread on cnc Zone.Cliff's notes version.You strip out all the old PC parts.On the stepper boards there's -,+,clock,DIR. The machine has a ~37V power supply. You run power to the +/- and step pulses go to the clock pin. Dir to the Dir pin. It's a pretty easy mod. That's enough to get you going. It's even better if you use G540 and replace the drivers. There's also a good chance the steppers are tired and you'll eventually want to replace those. Sure line is a good source for parts. A to Z cnc also makes some nice retrofit mounts. I thought it was a pretty decent machine to learn on. I've since moved on. Rob To: mach1mach2cnc@yahoogroups.com

                                            The hobbyist CNC realm of the internet is chock full of the 'bigger stepper
                                            are better' mentality. The problem is that is seldom the case. The stepper
                                            motors need to be matched with the job at hand (machine), stepper drive, and
                                            power supply. For a Sherline/Taig with the stock 20TPI lead screws a smaller
                                            stepper performs MUCH better and are less expensive. A smaller motor not
                                            only has less rotating mass it also generally has lower inductance.



                                            For a Sherline with the stock screw a bipolar motor in the 170oz-in range is
                                            the perfect fit. Take a look at:
                                            http://www.soigeneris.com/stepper_motors-details.aspx (my website). If you
                                            want to see how these motors can perform take a look at:
                                            http://www.youtube.com/watch?v=tYn9lCgZPEw (250IPM on a Taig, note this
                                            speed is not practical, it was done to illustrate the limits.) I keep mine
                                            tuned to about 90IPM.



                                            The stepper drives are as important as the motor. For these smaller machines
                                            the G540 is hard to beat.

                                            I think I was getting ahead of myself after I looked around some more. I
                                            found a site mentioning: The 425's are more powerful than what a Sherline
                                            CNC machine requires, and are not recommended for use on a Sherline. The
                                            rated torque from these motors is twice that of the commonly suggested
                                            rating for a Taig CNC machine. You should probably stick with the 269's for
                                            a Taig type machine as well.

                                            I found this on http://www.xylotex.com/425ozin.htm I am not familiar with
                                            the company, but I have seen the name around before. The 269 route looks
                                            like my best option.

                                            can cause it's own problems. Rob

                                                Great information on the stepper motors. After watching the video the 170oz motors will do just fine. Would anyone know where I can get a new table for my sherline? This machine came from a tech school and it does have some drill marks in it.

                                                  Order direct from Sherline- they supply every part for all their

                                                  business.

                                                  That is one of the best features of Sherline.

                                                    uncommon for a mills bed to acquire some scars over the years. If the bed is
                                                    still usable, but you want to improve it cosmetically, or so that a small
                                                    drill divot does not cause other problems you might consider just cleaning
                                                    the table and filling the spots with a high strength epoxy, like JB Weld. A
                                                    bit of time spent filling the holes and sanding them smooth should yield
                                                    very good results at a much lower cost. You can always use use a Sharpie
                                                    marker to color the filled spots to help them blend in visually.

                                                      I should have thought about Sherline, but thanks again for the heads up. The gecko g540 showed up. Last week I started to remove everything from the rear

                                                        I should have thought about Sherline, but thanks again for the heads up. The gecko g540 showed up. Last week I started to remove everything from the rear service panel to make room for the new parts. I remember seeing a wiring diagram on gecko's website. Should I follow that for wiring up the new machine? If anyone has any pictures of their set up I wouldn't mind taking a look :). Also, what kind of wire should I use for everything?

Would anyone know where I can get a new table for my sherline? This machine came from a tech school and it does have some drill marks in it.

                                                          I wired my G540 exactly as per the Gecko documentation, back in 2008. And it has never ever hiccuped since.
                                                          Re wiring, I purchased my wire in all the different colours from an Auto spares outlet. The wire gauge I don't know but it is what they use for wiring trailers for hooking up to your car. And I have the added plus in that I can colour code just about everything except what I had for breakfast. :-))
