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
