My hard drive crashed. I replaced it and reinstalled all the software Mach3 V2.48 with all my original settings. Now my 3 – 201A Gecko drives act like they are not micro stepping. Before the crash the motor tuning was set at 40,000 steps per inch with 50 speed on all 3 axis . Now I have to set them at 1600 steps per inch and 600 speed. Any ideas? TIA
