Problem setting current for x-axis

I was having problems with the y-axis chattering so I decided to go through the excercise of setting the current for the stepper motors. I managed to solve the problem with the y-axis (and a small problem with the z-axis) but have totally screwed up the x-axis. I start with the current at 0 and then slowly raise if and all I get is the x-axis sort of stuttering in place. There is no setting through the whole range of current that seems to work correctly.

Any insight is greatly appreciated.

Thank you,


Check if your wheels are not to tight on X axis.

Odd that it doesn’t move at all. Check that a wire has not come loose.

I checked all the wheels and they are fine.

It actually does move sort of. It makes noise and the kind of goes back and forth maybe 1/8" of travel. It is like a pulsing action.

I can take a quick video of it if this site allows you to upload a video.

Are you able to run this motto not attached to Z to see if it spins without any mechanical load on it?
