native34,
It sounds like you are accelerating too fast and stalling. Try accelerating slower and see if the problem persists. Are you using Mach3?

I am having trouble with my machine on two axis X, and A Y and Z are fine. I have previously used 4 G202's on this machine and had the same trouble always with two axis it doesn't matter what axis just two of them. The problem is while i am cutting a part or just dry cutting two of the axis wil stop and you can turn the motors by hand. I can turn power off to the motors then turn it back on and the motors will power back up and continue to run but at some point be it 5min, 10min etc.. the same thing will happen. This started with the G202's and Marriss spent several hours on the phone with me trobleshooting the problems each time resulted in sending the drive back for further investigation where there was problems with some component found so they replaced the drive only for this same thing to happen again. So finally i ordered 4 G203V's on marriss's recommendation. these drives had worked for a while then the same thing started happening again. only this time it was only one drive so i didn't use the drive for a while until i had time to address the issue but it started happening on another axis and now i can't use the machine as i can't rely on it. Could someone please help me troubleshoot this problem as i need to get this machine to a reliable state so i can start all the project that are relying on this machine with out wasting anymore metal as usually this happens when i am trying to complete a part.

I don't believe this is the problem as it also happens whne i turn the machine on not just running it. If i keep shutting the power to the drives and turning it back on it will eventually work long enough to run about 5, 10, 15 min etc.. what is troubling me is that there is no consistancy to this other than it will happen. What i mean by this is if it happened everytime i started a run or everytime i turned the IPM to 15 but it always just happens never on one particular event
Sorry i forgot part of the reply i am using Mach3
What do you have the step pulse width set to under "Ports and Pins"? Also, do you have the output set to "Active High"? On the COMMON pin on the G203V, do you have a GND signal going into it or is it the +5V that you used for the G202?
Marcus
Pulse width set to 2 under motor tuning the drives are set to active high and Pin 10 is set to GND and not using 5V
Good day
I know is an old post or is a late answer,
I saw many times same trouble, but the reson was on the power supply, if you attach a large capacitor, of at least 14000uf the power supply wont auto cut if it is an regulated, or wont magnetize like an regular lineal PS.
Hope this helps, since i had same troubles before and solved with this.
