Calibration issue (I think)
« on: July 08, 2018, 05:33:59 PM »
Strange problem.  I am using Mach 4 on a win 7;computer running gcode produced in Fusion 360.
I noticed that I was  a mm or two out of calibration, so I decided to recalculate all three axis. X went great, but I had to change units from 33.something to 60.something on the y axis.    Seemed weird sinse it was only out by 1.5mm or so, but I made the change and when I measured the y movement, it was spot on.  I did a test run (75mm circle inside a 100mm square).and x was ok, but y was almost twice what it should be.  I checked the calibration again and it still moved exactly 200 mm for the y 200 command.  The tool path appears normal in the preview window.

Is there some setting somewhere that would cause the units to be off by that much during a job even though calibration seems fine?

What is the Mach build number?
