Sounds like the machine is setup in mm's, but Mach3 thinks it's in inches?
I have it set to mm's in the settings and in the post processor. After clicking that box, I went to do this engraving and the motors (X,Z, & A) all turned 25 - 30x less than the file read in. The file would indicate X1.624, but the Mach 3 dashboard would have X.0594. The file would indicate X1.572, the Mach 3 dashboard would have X.0562. The A axis barely turned more than a single degree, but the jog rate is perfectly calibrated. It's just when Mach 3 reads in from the file it is doing some sort of conversion to lessen the steps the motor is taking in reality.
