Hello, I'm new amd trying to figure out how to tune my 620 oz stepper motors to mach 3 for my plasma table.
I ordered a gantry from precision plasma and electronics from candcnc. I have the 620 oz motors. The gears I'm using measure 11/16 overall. There are15 teeth on the Gears.
I've been trying to figure out the math and been confused. I've got it close on mach but still off a bit.

Can anyone help me out for the settings on the tuning screen? So my gantry moves the correct measurements

Do these links help?
