Hi all, I have been working through some issues with my Cnc, have made some new discoveries and thought id see if anyone knows why I'm having this issue.
VIDEO OF PROBLEM - https://www.youtube.com/watch?v=38lDOMZstBk
I have ruled out the following...
Drivers
Cables
Connectors
Steppers
Binding
Computer (tried a different computer)
ethernet cord
Thanks

What control are you using, LPT, USB, Smoothstepper etc.
You have the A axis home and the probe on the same input.
If you are using LPT then with the settings you have set in the motor tuning you may be running out of steps at 25000Hz.

Sorry I didn't mention it has a ESS.
I will check on that input, I don't have a probe setup so not sure how that happened.

Can you jog any single axis and it works as it should even if you hold down the shift key (Rapid Jog)

Yes I can jog and rapid jog one axis at a time (500ipm on X and Y, 187ipm on Z) no problem.
I think I may have found the problem, my BOB was outputting weird voltages for Dir and pul. Around 3.5v and -1.0 depending on direction...
