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

**fasteddy** · 06-10-2011

Still happens with the ballnuts disconnected, I had removed the ballnuts last week and cleaned them out, then tested that principle as I was originally thinking along the same lines.. The problem can happen at any position on the bed (2mt x 1.4mt) although it seems to happen much more on moving the x axis +, rather than -..
Mechanically, the machine is sound and I have torn apart and rebuilt it twice in the last week, everything is freely moving..

If I get a chance, I will make a little video of it happening later today..

at what RPM on the motors does it stall? is it at the same speed all the time? Do both motors on the X stall even if they are not linked mechanically?

It is stalling at all speeds.. Had it as low as 500mm/min up to 2500mm/min.. Acceleration from 10 - 120.. Stalls at any speed.. The x axis is completely unaffected by the z axis.. It only happens when the Y and x is both moving at full speed..
