I'm using very small diameter bits (1/16 and smaller) to cut out my widgets with. So far I've snapped off about $50 bucks worth. Lubrication helped allot, slowing down the feed rate helped... but... If I stop the run, and then restart it, it goes into over drive. I had it happen with a 1/8th bit and it actually survived something like a 50in per min rate when it jumped. Of course, the aluminum I was cutting looked like it had been ripped apart, not milled. When this happens with the smaller bits, *poink* more money down the drain. Is this a bug in the software? Anyone else run across this?
