Fehlmann Picomax 50 CNC conversion/refurb

Try the attached spreadsheet (I use LibreOffice if you don't have excel)

Just enter the desired spindle speed in cell A4 and it will calculate the inverter frequency and contactor to energise.

That logic needs put into a Brain using Mach3 DRO 169-Cmd SpindleRPM as the desired frequency.

It uses an inverter frequency up to 100 hz and assumes the manual adjuster is set to 1.5 * motor speed, so for the 1400 speed it's set to 2100 RPM then the inverter will take it to 4200 RPM

Thanks, that's really kind of you. I do have Excel so I'll take a look.

Can anyone tell me what G0 code will make the x axis move +100 back to zero and then +100 repeatedly - say 10 times? I'm looking around for a simple answer but can't seem to find one.
