Ok, I have my new machine running. I am using the CNC xPRO V3 Controller Stepper Driver board that came with gbrl 0.9. Made a few test cuts, and ran into a problem trying to cut radius. it seems to want to travel straight point to point in a diamond shape, rather then in an arc (g3). Is there a setting on the board that I am missing? Update: After posting, I did some more research and found the setting I was 'missing'. Turns out, the "arc tolerance" was set to 0mm. I reset it to .001 and now it runs circles like it should.
