I'm running a PRS Alpha with 2.2 hp spindle, 1 year old.
Operating with shopbot link.
Up until now my hinge pockets have not cut accurately, so I am trying to analyze the problem.
I have run some tests outside of shopbot link and discovered the same problem when cutting simple holes through Partworks.
The holes are not round and have flat/straight portions along the x axis.
My first thought was a loose Y carriage, but having tighten that up, still the same result.
Second thought was bit deflection.
I have tried slowing down the cut and only cutting an 1/8" deep, but still have the problem.
I have tried raster and offset.
I could set a separate tool path for the final size for the trials in Partworks, but I don't think that's possible in shopbot link.
1/4" compression bit, 10000rpm, 10ipm
I have found other threads on the forum that discuss similar issues, but none that end with an answer that I haven't already tried.
