My X axis was out by about .05" after I cut a 30" dia. 3" wide (circle radius) molding by a manually created method similar to how the Extruder works.
I created the tool path with about 60 concentric circles offset .05" apart and then set to elvations so that the cove cutter would shape the profile that I needed. I connected these circles with a short vertical step and a X move to the next circle in the path. At 2" cut speed it jerks just slighly at each change.
I have a 4G PRT that started acting up and lost its position by several inches a few times that same day.
I am also waiting for the arrival of new replacemnent pinions.
I can't think of any other factors as to cause of my problem. Perhaps grounding for a 4G any, special needs?
Before I try to create another piece of $300 worthless MDF I thought I better seek out any advice tha might be offerd.
Thanks, Robert
