Hi,
I just had my machine repaired today and everything seems fine. Everything is working fine in manual mode. The issue I have is with the Sub spindle in manual / Rapid mode it spins fine in both directions at whatever speed i select. The trouble is when I use M303 or M304 (with an S value of anything) in either a program or with the test button it won't move it just seems like it is trying to move, you can't move it by hand it's solid. It seems strange beacuse it spins fine in rapid or manual mode in either direction. M306 and M307 (Chuck open / Close)work fine. Any ideas ?
