Problem Fixed!
I found out that my Y axis linear bearings were way too tight. Once I disconnected the Y motor, I could barely move it along the rails. The linear bearings have small set screws that will tighten the bearing around the rail - so I loosened them up so I had free movement along Y and did another circular pocket test and now all is well. -It's a good thing I fixed it because the backlash config in Mach was a little screwy - once activated, the job did not run properly. |
