Hello Gents
I have done the calibrations of the stepper motors, using a dial indicator, to measure the distance each stepper motor traveled. Used a steel ruler, to check the longer distances, which each axis traveled. All is 100% correct there.
Now I machined a circular pocket of 20 mm dia. It measured 19 mm.
Machine is in Constant Velocity Mode.
The stepper motor drivers have been set for micro stepping.
I do my designing in Fusion 360 and then send the file in a .nc format, to the UCCNC software.
Any suggestions, to where or why this is happening?
Regards
Craig
