The Fanuc spindle drive has 6 transistors on the board, so that seems like a clue it must be AC. Induction or PM, I have no idea. Can anybody be good enough to send me their configs file set? I know how to get the axes and spindle working, but have never dealt with a tool turret. I used John T's setup on mine. The only caveat is that it does not verify the tool number after the turret settles, mine will on rare occasions at first start skip to the next tool and try and work with the wrong tool. Hmm, that is not nice. Could cause an expensive crash. This guy wants to make up to 30,000 aluminum housings on it. I think he's NUTS, and am pretty sure he will eventually go to China for either turned or cast parts. So, I think he needs a reliable solution. Might take just a little hack to the classic ladder to fix it. Thanks, I'll check with John T! Or, is it online? I looked around, but did not find it on the git repo. We think the machine is set up for the 16C collet, and has the air collet closer. 16C spindles have A2-5 noses, 5C have threaded as far as I have seen. Right, there's no thread on the nose, just an outside taper, so it must be the A2-5.
