Machine repair guy came in the other day. The switch was out of adjustment. The 4th axis uses a mechanical switch to find home and it needed tweaked. All good now!

I did alt-i and the 4th axis circuit red all the way around. I can't access the switch without taking the axis apart, prefer not to do that. I tried just manually homing it to some random position and it worked. I re-zero it every time I set up anyway, so home for this axis is pretty pointless. So w...

4th axis won't home. Worked great yesterday. Shut down the machine last night, come in today and it just spins and never finds home. It spins really really slowly, too. Normally it rapids around, trips, and then touches slowly. It's just creeping around now. Made several full revolutions at this poi...

Reply from Centroid showed me where to find the home program and suggested an edit. Put a semicolon in front of the 4th axis moves. That stopped the machine from trying to home that axis, but it seems it didn't complete the homing cycle enough and the control still says the machine is not homed. Bot...

My 4th axis blew up, I'll deal with that issue later, but I'd like to be able to use the machine without the 4th axis. Unfortunately, it won't home without homing my 4th axis also. I'm dead in the water now. Is there a way to edit the homing process to remove the 4th axis? Pics below are my screen w...
