i'm with Caprirs
the stuff is brutal on the coolant system , plan to spend a few hrs or more draining the tanks and flushing the system clean , the stuff gets everywhere ,and takes a lot to get it all out of the machine , ive worked with loads of the stuff , it is nasty everywhich way , i hate it !
you'll know your cutter is too dull when you see some delamination (watch for light spots) , you need to keep a decent feed rate but at the same time keep the speeds relatively low or you'll burn the cutter out prematurely , it is very abrasive material no matter how you look at it
i wouldn t machine g11 on a machine i liked !
it is by no means healthy stuff to be breathing in so i would suggest some type of ventilation and plan to get vert itchy if your working with large amounts of it
