Y axis is making X axis stall...!!

[JAZZCNC]

Disconnected the X and Y motors from their X-Y table. Unable to reproduce the problem of horrible sounds and missed steps described above when MACH3 jogging the motors at full speed. I'm becoming convinced that, since the X and Y-axis move very smoothly on their own, that the issue - in my case - is related to some resultant force vector in the heavy X-Y table causing table twisting and thereby increased friction and too high loading on one or both of the the motors (even though motor currents seem low). I can't tell by sound or feel whether it's the X or Y motor generating the noise. A mystery that's annoying and puzzling.

Sounds very much like you have some binding then or if it's X-Y table that uses dovetail ways with jib strips then you could have some slop enabling the table to twist and jam.?
If so then I would strip down the table and check for any chips that have got lodged or stuck, clean all surfaces carefully checking for damage or high spots.
Re-lube the ways and rebuild being carefull not to over tighten but still enough take out any slop then try again.

Good luck.!

Steve I'm clutching straws for you here but it may be worth trying another PP cable.?? Will at least be another part of the elimination process.!

I'm pritty sure you have a pulse issue and this where I'd be concentrating my main focus.!
