Ok guys, I’m losing my mind here. everything was fine, I’ve been using my mpcnc a lot. Everything was working amazingly well. Little background, when I first put it together I had one X motor not working. I’m using the ramps board with dual endstop firmware. I switched positions of the motors, meaning X1 and X2, and everything worked perfectly.
on repetier host I did change the travel feedrate from 4300 to 2100 as suggested. Now I’m in a world of problems and simply can’t figure it out. My Y and Z axis move just fine. I have checked continuity on all of my wiring, I have swapped X and Y on the board. The X Axis, one motor will move, but sounds like it’s skipping steps or is in chop mode. The second motor will move if I bump the feedrate movement to somewhere around 10000 but still makes a terrible grinding noise and doesn’t move quite right and seems to change direction on its own with no rhyme or reason.
I have reflashed the firmware twice, only changing steps per mm to half of what they come stock because I’ve already figured out that stock is double size. What else could it possibly be? Everything was working perfectly fine.
Edit: just switched X and Y, same motor is still doing the same exact behavior
The motors are usually very robust. I would strongly suggest checking the wiring along with the motors. The wires heading the motors fail quite often. The motors themselves, even the wiring in the motors, almost never fails.
I’d say this is more likely if it’s not pushed hard enough. I had a sketchy connection that felt loose and later found it melted. I presume it had poor contact and some resistance, which with the motor current turns into some dissipated power that’s not insignificant.
