Hey guyz, I bought this MKIII when it first came out. At one point it was in perfect working condition; however, it developed some slop in the...
When I tell my machine to jog 4" on Y, it jogs 4" to a precision of .000. When I tell it to job 4" on the X, it jogs 4" to a precision of .000....
I just tried the circle test that's posted in the thread with the new cncusb settings. My circles look best when I have no backlash setting, but...

Thanks dhc9guru. I don't have a temp gun but I'll try to find what you're talking about on the board and see how hot it gets. I had a problem...
I just tried 200 inches of X movement on a sheet of depron and on a sheet of fanfold. The fanfold skewed a fraction of an inch but just barely -...
