Another funny thing. My setup units are all metric, which is all I ordinarily use.
If I home the machine, and assuming G54 offset is zero, the work coordinates DROs read 0. If I issue a G20 MDI command, then jog X 1 unit, then issue G21, the X DRO reads 25.4 afterwards. If, however, I First switch the display to machine coordinates and then follow the above sequence, the DRO reads 1 afterwards. This doesn’t make sense to me. I can understand that Mach4 may, by design, change the jog units to imperial when the current units are so changed by a G20 command, but why would this depend on which coordinates are on display?
Above with 3485 and SIM. Sounds like another bug to me.
