I've got a DMG machining center with a TNC426 controller. Today, in the middle of making a part that we had already made several runs on, our machine went to change tools and, after changing, gave me an error "M3/4 NOT POSSIBLE". I can clear the error but when I tried telling it to restart (either where it left off or starting fresh) it pops back up and the spindle doesn't move. After several attempts to start the program back up, I tried rebooting the controller. It rebooted successfully and went through all of startup just fine, but when I attempted to do a manual M3, it gives the same error message. Hoping someone out there can help me figure this out!
