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

Yes,, you have it set as metric for your native units

Yep, You were right on target. Thanks sooooo much. A day of checking this and that with an onset of depression and doom in sight but you saved me with one post. I'm impressed thanks.

ha ha lucky guess well not really, its the only explanation there could be and 40,000/1,600 = 25 and there are 25.4mm in 1 inch.
