Also how do you use Metric units with the wizard?
I have not tried, but if you enter a G21 in mDI before starting the wizard, then simply entering your metric values should work.
In the video you popped up the editor window, how do you do this?
Do oyu mean the keyboard popup? Thats called AutoCalculator. Click on the Operator Menu then click AutoCalculator. It will stay work until you click again to turn it off. Then simply a click in any DRO and the keypad pops up. I love it at my desk because I can do all entries without letting go of the mouse.
Can I record a file and save it, and then just run it in the Mach 3 window?
Yes, thats exactly the idea of the record function. The saved file is simply Gcode, it does not need the wizard to run.
No problem asking questions, thats why the forum is here.
