General Mach Discussion / Re: Set Steps Per Unit function not accurate
« on: July 11, 2014, 03:49:54 PM »
I went and got it set up as good as i could in mach3. Went to Vcarve Pro, designed a single circle with a diameter of 5.7". Put the code into mach3 and let her rip. X = 5.705, Y = 5.701. I was pretty happy with that. Then I checked the diameter of the arches between X and Y and I got diameters from 5.694 to 5.725. Is there a way to tighten up the transitions between X and Y? The arches do not seem to be very uniform.
Also, I did end up using backlash compensation in mach3. You said its better to fix the problem, how does one go about fixing backlash? I am 99% sure every single screw/bolt is tightened. I had this machine dropped in my lap to work with and the owner has no idea about mach3 or computers, so I have had only a few months to teach myself how to use mach3 and vcarve. So I am pretty new to this still. Any tips would be appreciated.
