This is a serious riddle. I use g28 then g29 before each print and have for a long time with great results, I usually manually level the bed every so often just the bottom of my prints isn't too skewed. Today I was printing without problem, did literally nothing. Jumped a step and realized my Y stepper was getting a little too much juice and rolled the pot down a bit. That's literally the only thing that changed today. I just tried to go a print, g28, g29, does the probing, echos the coefficient and matrix like normal, I jog the axis and notice my Z motors aren't compensating (no my matrix wasn't all 0s). Why on earth would g29 suddenly function, but then fail to actually apply the calculation. I didn't update firmware, change settings anything. Any ideas!?
