Have a new machine setup with Blackbox motion control and OpenBuilds Control software. Setup was straightforward and machine is working as expected. Calibrated the steps on all 3 axis with a dial indicator, jog function in control repeats reliably - all good, except when jogging 1" (on any axis) the DRO shows 0.039 inches.... I'm thinking there is something not set right, but have not been able to find it. GRBL setting ???
Possibly, make sure you have $13 (report inches) set to 0/disabled CONTROL is all millimeters internally and does the display conversions for you
