I'm gradually learning an 840D Shopturn cnc lathe, and have downloaded Sinutrain for Sinumeric Operate version 4.8
I'm going through a good Youtube tutorial to learn the programming but the problem I have is this tutorial is working in inches and my Sinutrain simulator is in mm.
I cannot find anywhere to temporarily change the units from mm to inch. In the tutorial there is a box in the Program Header where you can choose mm or inch. My Sinutrain simulator does not have any such box.
A 2nd question I have is what is the difference between a "Part Program" (.MPF file) and a "Workpiece" (.WPD file). When creating a new program it seems I can choose either, but I don't understand the difference between them, and have not yet found any information in the user manual.
Thanks,
Keith.
