John,
http://www.youtube.com/watch?v=-DwrXKvqqOYThere is a video showing what the machine is doing.
Like I said earlier, everything was working and performing as it should have until about 2 weeks ago. I know my motor wiring and mach settings are good, however I will attach my xml file for you guys to proof read if need be.
My only change was physically attaching my home switches to the machine. Before they were wired up setting on my desk and I would activate them when an axis was close enough. I wanted to start using fixtures so I needed a consistent machine zero and that's when I drilled and tapped some holes. The home switches do not have any shielded wire, but I unhooked them from the power supply over the weekend and the machine was still losing steps/stalling.
There are no binds on the Y axis to cause the motor to stall and my acceleration and velocity settings have been the same for a year.
I can try swapping parallel cables to see if that helps but I doubt it will.
Videos speak louder than words.
Any help is greatly appreciated.
Chris
