If object dia is 96mm do you set the steps per rotation 96000. Using a chuck rotary? When trying to put a 20mmx20mm square on a tumbler it comes out 20mm tall but real thin, not 20mm thick.
The steps/revolution with the same device and stepper motor driver will never change.
With a chuck rotary the only change needs to the object diameter.
Go back to whatever you were using, which is what is set on the motor drivers. My fiber and most others seem to 12,800 steps/rotation… Once set, leave it… then only the object diameter needs to be modified if that changes.
In simple terms the software/controller needs to determine surface speed, so it needs the diameter.
