Hi --- first time poster.
I'm pulling my hair out with this problem that happened at the worst possible time in the middle of a big job--too late to outsource, so I'm hoping to get some troubleshooting help up here. I'm running Mach 3 on Windows 7, with a K2CNC KG-5050.
First a little back story. Like many posters up here I've had a hard time getting help from K2, and even less because I bought the machine used. Being that it was only two years old I didn't expect as many problems as I've encountered, but it doesn't help that I'm a complete newbie and got the machine with the intention to learn how these things work. I've learned a lot and even done a couple big jobs on the machine, successfully, but just barely. I've had a lot of problems with the machine creeping around small amounts during cuts and especially while sitting idle, throwing off my registration. My partner seemed to have fixed this by adjusting the debounce, and we suspect that there are electrical issues in our building. The biggest problem is the little red light on the controller box coming on for no apparent reason. I often have to hit the enable button a bunch of times right when I turn on the controller before the red light fully stays off. The worst scenario is usually that I'd have to shut everything down completely and restart, and everything would be fine. Unfortunately I put off finding the source of the problem for the sake of getting through work on a busy schedule.
Today was different, and maybe my neglect caught up to me. After a few annoying hiccups, involving some creep and random shut downs, restarts--- not a good day-- the machine completely shut down near the end of an hour long cut. I attempted to raise the z-axis and it was jerky, and then stopped, never to move again. I've tried everything I can think of--restarts, reverting to past settings, unplugging and replugging everything back in -- but no movement at all. Mach 3 shows movement on the screen, but the machine isn't going anywhere... and actually the one revealing thing is that the red light no longer comes on at all except when turning on the machine.
If anyone can suggest any troubleshooting suggestions, I'd really appreciate the help.
