gday all hope someone can please help .Since i got my sx3 mill running always had problem with zaxis stallin and clunking running at reasonably slow rate. I had put this down to mechanical issues ie alignment etc. have stripped head off removed stepper axis feels fine by hand. Bench tested stepper runs for few revs then clunks/stalls. Under no load. Have checked wiring seems good. Excluded driver error by swapping over axis .followed motor have checked/ changed all setting s. I know of ,wired bipolar parallel. 3.5k current limit res. Don’t understand doesnt matter what velocity etc always runs for bit then stalls! (nema 34 m906oz/in of g540) Any suggestions/ help be appreciated. Thank you

Hi Kooka,
You have swapped axis and the problem follows the motor.
Are you saying that this particular stepper motor is the problem or are you saying that the G540 output for the Z axis is the problem ??

gday tweakie, am sayin it is the motor. have even tried connecting different configs like half coil etc and runs for bit then stalls not at any particular velocity at through range faster more severe of coarse.. can turn by hand relatively easy when not energised. i am thinkin must be a dodgy motor?

Hi Kooka,
I am inclined to agree with you - dodgy motor.
It happens :(
