Reply with QuoteNormally, since it's the longest one, you'd call that the X axis. What's happening is that the motor is being over-driven, so it's faulting and losing steps. Try reducing the acceleration until that stops happening.
Scotle 6040Z jamming Y-axis
I´ve had my CNC for about one week now and )´m having trouble with it jamming on the y-axis.
Any ideas on whats causing this??

Re: Scotle 6040Z jamming Y-axis
Had any luck erock?
I had a similar problem with my X61500GT after a few months of ownership, but in only one direction.
I had to partly dismantle my machine to get to the core of the problem, I ended up finding 3 or 4 problems.
Each one small but they tend to add up...
With no power on the stepper, you should be able to turn the ballscrew with your fingers with very little resistance. Mine was bad in one direction(?) I have dual shaft steppers with a plastic knob on the end to do this. You may not.
Check all four bearing blocks for smoothness. I had 2 that were binding.
My ballscrew had -2.8mm clearance from the mounting block, ie I had to shim the gantry bottom 2.8 AWAY from the ballscrew. It was deflecting it.
Check motor alignment...make sure there are no side OR axial forces acting on it.
I replaced my complete ballscrew. I could not see any damage, but I couldn't stop it binding either. Was fairly cheap to order new one.

Use light machine oil on the rails and keep clean.
Re: Scotle 6040Z jamming Y-axis
Sounds like you have a under powered motor or your velocity and/or acceleration is set to high.The stepper motor is stalling out (loosing steps).
