General Mach Discussion / Re: Motor tuning mach 3 - mm? or inches?

« on: March 09, 2013, 12:47:21 PM »

Looks like thats working, going to test the accuracy. When I put in the velocity as 78.74 and save it mach changes it to 78.72, any idea why its doing that? Will that affect the accuracy of a cut or is it really the steps that are accountable for that?

General Mach Discussion / Motor tuning mach 3 - mm? or inches?

« on: March 09, 2013, 10:12:35 AM »

So I purchased one of those Chinese knock offs, it actually runs fairly well but I need some help... In Mach 3 they have you set it to mm, then motor tuning set steps to 400 , velocity to 2000 and accel to 200. This is for x and y. It works well enough, but I need inches! This is where I need help if I change Mach config to inches the cnc doesn't like it at all. Is the motor tuning in mm and need to be converted? Need help going from a mm setup to inches...

This is the cnc:
