Hello,
I had some issues over the weekend while using a maker space ShopBot. I am cutting Polycarbonate 0.375' with a 1/4" single flute "O" up cut - Onsrud. (I have cut the same part with the same bit in, on a Laguana with no issues).
Speed 18,000 IPM 60, depth of pass 0.100" 4 passes. The center hole is not circular and the tabs cause a gouge in the periphery circle.
ShopBot Circles cuts out of alignment
