Hi Lee, Something around 33uF should suffice. -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ ... From: Trend [mailto:fredit@...] ...
Hello, I'm using the latest xylotex 3 axis controller to run my steppers on my cnc router machine and have a few questions. My stepper motors came from a guy...
Jason, I bought the same motors from the same guy. I also have had no luck finding specs for these on the web. Also, my motors arrived with no wiring...
JB, I wish I could've helped you on the connectors, because I just ordered the same ones from DigiKey as well. I got mine last Friday, and they work well w/...
If you're using bipolar motors, here's a good way I found to determine if your wiring is correct. Connect the 4 coil wires to the controller in any pattern....
Hi, PLEASE! NEVER arbitrarily hook up motors to the drive. This can cause the drive to blow-up. Use an ohm meter to find the correct wires to a phase. Or find...
... That's not really correct. A unipolar driver works by energizing one of two coils that are wound on the same mechanical poles, but in different directions....
I am currently setting up a 3 axis Xylotex board with my homemade router and have a few questions. I have a combination 24/5 volt power supply and was...
Dave, ... two ... I'm currently wired using the full winding on each phase. So you're saying that by swapping the two wires on one phase will simply make the ...
Hi Jason, If you're using unipolar steppers, and you use full winding mode, you should set the Xylotex controller for 1/2 the rated current of the motor. If...
Jeff, My apologies for the confusing reply. I understand that the correct wires for each phase must be hooked up to the correct pins on the xylotex, and I...
Hi Jason, Cool. Jeff ... hook up ... matched ... phases ... for ... the ... winding. ... what ... I ... motor ... driver ... of ... I ... The ... I ... But, ...
Hi Bob, The PC parallel port should already be running the program (i.e. TurboCNC, Mach2,...) before powering up the drive, so that the STEP & DIR lines are...
Thanks, Jeff. What about with the test program - test.exe? Does that hold the lines stable so that I can power up Vbb and Vcc? Bob ... & ... This ... without...
Hi Bob, If you run from DOS, the parallel port lines should be stable AFTER it completes the boot process. Parallel port lines may (and probably do) change...
Jeff I am having trouble with the estop diagram whats the ourose of second circuit And whats the safest way to turn power on to the board is there a way to...
OK Guys, Now I'm totally confused as to how to wire these motors. Can someone please help. I tried to check the wiring info Jeff refered to in an earlier...
i bought some stepper motors off ebay they are japan servo model kp56lm2 097 and i hook them up for testing with my xylotex drive running turbo cnc and when i...
... That's correct. A stepper motor is basically a 2-phase motor, and making it rotate requires supplying 2 sine waves 90 degrees out of phase. (Sine waves ...
... Ok. It's obviously a 6-wire motor. Pins 1-3 are one phase, with pin 2 being the centre tap. Pins 4-6 are the other phase, with pin 5 being the centre...
JB, Okay, I've had a *little* success getting all three of my motors(which are identical to yours I believe) to work. I have my six pin motors wired using the...
Guys, I decided to use one of two Superior Electric bipolar stepper motors I have from a robotics project to see if I got any different results,and, I did!...
... And what was the power supply voltage when the SE motor was in use? ... Changing from unipolar full-step or half-step to bipolar full-step or half-step...
... Measure the current drawn from the power supply. If the current is 3 A or less (like it should be) and the voltage has drooped to 5.7 V, your power supply...
Well I'm ready to kick the tires and light the fire on my cnc machine. Prior to doing it I would like to expert advice on setting up Turbo CNC for my Xylotex...
Dave, Did you want me to measure the current at the power supply while the motors were running, or while they're not running, or should I measure it at the...
Woohoo!!!! I got my motors working correctly!!! The power supply WAS the problem! I used a motorcycle charger rated at 12v, 1 amp as a power supply, and...
Hey Guys, I too would like to thank everyone here who has contributed to this discussion. I have had somewhat of a success myself. I wired the motor as...
