General Mach Discussion / Re: missed steps on Y axis

« on: July 21, 2011, 07:49:53 PM »

I swapped the X and Y axis at the G540 and the miss followed meaning the problem is in the 540 , the computer or the cable (as you said, hardware). I thought I had the pulses set wider then that so I set the step and dir pulse to 3 and it seemed to be OK but I will have to wait until the weekend to test it some more, I remember having to increase them to get smooth movement when I originally set everything up and I also remember changing them when I was messing with the 4th axis, sure hope that's it. I also tried the Sherline mode but it just growled at me for doing it. Thanks for your help I'll keep you posted.

My power supply and steppers are probably overkill for the machine and the G540 is said to be bulletproof, I changed the accel and velocity settings but that didn't help. I'm not looking for someone to fix it for me just someone to guide me along or at least point me in the right direction.

The Y moves but randomly misses steps/stops moving, when it does that I can watch the DRO move up/down but there are no signs the stepper is trying to move so I don't think it's mechanical, It was working fine and I was running Gcode to engrave key chain blanks but then I tried to add the 4th axis, after that I started to get the missed steps.

No stalling heard even if i push on the handle to help it along I can still watch the DRO count up/down with no movement or signs /sounds that it is trying to move the Y.

General Mach Discussion / missed steps on Y axis

« on: July 19, 2011, 06:29:14 PM »

I need some professional help (or so they tell me), I've read as much as I can about the issue but just keep going around in circles. I am running Mach 3 on a Vista machine controlling a G540 running steppers on an X2 mini mill, I HAD everything running smoothly until I tried to add a 4th axis (a lathe head with a 4th stepper) it worked ok except that it would randomly miss steps on the A axis and I couldn't figure out why. I had other projects piling up so I took off the A axis and set it up like I had it but now it's missing steps on the Y axis??? There is no binding in the ballscrew or ways, the X and as far as I can tell the Z axis are ok,  I reloaded Mach and tried to set everything as close to original as I had it but that didn't help, it will do it running known good Gcode or even jogging it with the Xbox controller,  seems like a program problem but if I knew what I was talking about I would be able to fix it myself?? any help would be greatly appreciated, Thanks Jim

Hello everyone, I'm new to the site and it looks great. I have Mach3  loaded (running Vista no probs yet) and have been playing with it some, pretty cool so far. I will be starting the wiring soon using the Gecko 540, KL/600 48V power supply and NEMA 23 318oz and 387oz motors. I have some E Stop and limit SW questions but will ask them in the proper section after I do a little research. I have a strong mechanical background so doing the mods to my X2 mini mill shouldn't be to bad but I will definitely need your help with the wiring.
 Thanks for the great site and allowing me on.
