G4 CNC Software Update


OmniTurn continuously improves the G4 CNC operating system in response to the needs of our customers; ’bugs’ are fixed and features are added. The update procedure is quick and none of your existing programs or tool offsets are affected.

The current software version is 11/22/22. To discover what version is installed on your OmniTurn, press Alt-D in Jog Mode. A list of exe files will appear. Note the date of "auto.exe" file.

NOTE: If older, fan-type motherboard is replaced with newest fanless version, this update is required.
