Learnt a bunch from the First Acrylic Cut Advice topic
Curious what Polycarbonate cutting settings are working for your MPCNC / LR3 based CNC builds? Guessing slow low-speed deep trochoidal cuts with 1 flute carbide 1/8" bits, ideally down cut, but up cut can work too for thicker less flexible stock? With great Vac and/or air assist to clear chips.
Currently planning to use my cast acrylic settings (thanks to the Acrylic topic) as a starting point (LR3)…
Cheers!
