MPCNC, Jackpot board, no changes to firmware/YAML. It was working great for a long time. Now whenever I try to home Y, I get " Homing fail. Pull off travel failed to clear limit switch. Try increasing pull-off setting or check wiring."
Well, thank goodness the Jackpot has those LEDs for limit switches. I verified all four work as intended manually. I even tested the Z probe light, and made sure it wasn’t touching. (Does that even matter btw?) All this tells me the limit switches are good… right?
So maybe something is weird with stepper motor wiring / connections. What’s crazy is I can move/jog every axis and all motors work. So if it’s not the motors, and it’s not the limit switches… I’m stumped.
Curiously, the console shows Pn:YZ, which I think means the Y axis is touching the endstop. The endstop lights on the controller itself indicate otherwise. Why isn’t the console getting the message?
When I do “home Y”, it backs away from the axis instead of going toward it, like it is trying to do a homing pull off. But WHY?
When I have had this happen on my MPCNC it was where the endstop extension wire plugs into the main wire that goes to the stepper driver and the endstop on the Jackpot. For whatever reason it was loose.
Yeah, I’m thinking hot glue may be in my future. What threw me off is all the limit stop lights worked. I just didn’t notice it was the Z light instead of Y2. Man that was maddening!
Everything is working great now.
