This really does come under the heading 'Asking for a friend'.

My son-in-law works at a college which has a Denford 2600 Pro. The Y axis just judders when you command it to home. Nothing else (apart from homing X and Z) works until all is homed. He has checked wiring to drivers and all seems OK. I have not seen the machine and I am assuming it is a stepper driven gantry jobbie.

I have suggested he checks the connections at the motor end as there may be a fractured connection.

Any other ideas for checking?


Cheers,
Rob
