Has anyone here used the screw mapping function and provide some feedback? I've searched but came up with very little info on this feature.
I believe I have some error in my rack and tried to use the screw mapping function in mach 3. I bought a 35" DRO to measure the actual movement and mapped my X axis. Once mapped I tried to run a program and it resulted in missed steps and the X axis double backing on itself in a straight line move along the X axis. So I then turned off the screw mapping and ran the same program and everything ran fine.
The screw length defaulted to 1300 (I'm unsure what unit of measure this is I tried entering my screw length in an inches value first being that's what I use defaulted in mach 3 and then I also used a value in mm) I can't figure out how to save the screw length. I've tried multiple times and it always defaults back to 1300. Does mach 3 pull this value from somewhere else? If so where and can I change that?
The second problem I believe is self induced where I entered the wrong value and saved it as a data point but then I corrected it with the correct one after that. (hey entering 200 points your bound to make a mistake) It was easy to see if I entered it wrong usually because I was an inch off of the correct measurement and the screw map went sideways, once i entered the correct number the map leveled out.
