I have a hurco sm1-cnc that has been upgraded with a tape emulator. Everything worked fine for the last 5 years I’ve owned it. Now it runs in manual fine, and you can dry run it in auto. But when you try to run it with the spindle on it won’t run in auto. Spindle runs fine in manual. When you turn the spindle on in auto and go to hit start, the start and motion hold lights don’t come on and you can’t start. In dry run it works fine. Any ideas?
