Grinding Z steppers
I've had my Duet Wifi up and running for a couple of weeks now and decided to print an enclosure for the board. I also chose to extend some of the wiring to provide a bit more room and flexibility for the enclosure placement.
Anyway, since this bit of work my Z steppers are not working at all (cartesian printer with two z steppers). I've double checked the wiring but when I submit a G1 Z1 F6000 S2 command I get a horrible grinding from both stepper motors and nothing happens.
Could be a damaged wire on the stepper plug. I've had that before. Use a multimeter to do a continuity test on each wire of your plugs. Could be a break.
Did you change the stepper current?
Is the Z axis aligned? If it got out of alignment it could be binding.
Cheers, I did have a connectivity issue as you guessed. Fixed that now but still happening. I think I may now have a couple of wires in the wrong place. Will check on that when I get a minute to take a look
I changed no settings so the stepper current is the same as before.
Yeah, I have some calibration posts I use to ensure the Z axis is aligned and the Z axis moves freely when the motors are off
Happy to help
All working now, thanks again
