      Alex & all
       
      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

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 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.

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.

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

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 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.

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?

              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.

                    Order direct from Sherline- they supply every part for all their
                    machines, and have maintained compatibility since the start of the
                    business.

                    That is one of the best features of Sherline.

                      There are many Sherline dealers around (like myself) who can set you up with
                      the parts you need, you can also get one directly from Sherline. It is not
                      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.

                      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

                        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?

                          ... Alex and group, 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

                            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. :-))
