BeagleBoard Black with Cramps - X stepper vibrates and does not rotate

[John Hammond]

The Y and Z steppers rotate but the X one does not. I have switched the Polulu driver from the X to Z and it works fine. Where is the pulse rate determined in Linux? Does Machinekit have linuxcnc files that I haven’t seen? Should this be posted on Machinekit forum somewhere?
Thanks,

Folks on the Machinekit forum would be better at those details, but... if you are seeing twitching, could it be as simple as that axis has too much resistance? There certainly is a config file to specify the pins for pulse/direction. You used a standard CRAMPS board, right? Who built it and can you verify the connection? Any logs to share?

Thanks,
