Speaking of Mach3 & CV...
I never had a rounded corner problem till I started using faster feed rates and slower spindle speeds. I was making dust (and sometimes smoke) but had nice square corners. Now I make chips and have rounded inside corners, but square outside corners. I guess that's progress, eh?
Yeesh, all the Mach3 CV stuff is complicated. I've spent hours searching & reading about the CV settings, and still haven't figured out what all I need to change, or even what to start with.
Somebody please buy the same router & control box I have, get it set up properly, and then let me know the settings.
OK, here's a specific Mach3 CV setting question that I haven't found an answer to. CV Dist Tolerence Units. Mine is set to 180. But, 180 what? What are the "Units"? Inches? Thousandths of inches? Stepper steps?
