Z axis sync.

Hi,
When raising the Z axis I notice that one side is lifting faster than the other, is there a way I can fix this.
Any help would be appreciated. thanks.

Are two z motors connected to same stepper?
Did you adjust the voltage for two motors?

Thanks for the reply.
Yes both are connected in parallel to one driver.
Not sure how you adjust the voltage for two motors

I have dual Z-Axis Steppers, they are wired in Parallel. They could be wired in series and would have the same affect.

I have Nema 17 from the factory one Z-Axis Stepper would get hot the other was fine, This however did not cause the stepper to become out of sync like yours.

Just mention this because you could have a defective stepper, or might need to adjust the stepper motor current, it could be that one is missing steps because of not quite enough current.

calculate the motor vref and double it for z stepper
(like if x stepper 350mV z stepper 700mV)


if you have an avo meter chek youtube for "how to adjust stepper current ramps" ther are many good videos teaching how to do it

Looks as though your are correct Clif,adjusted the driver and things are working fine thank you both for your help.
