Hi Guys - I have X upgrade and Z upgrade and it worked well. I recently had to replace the Printrboard (bot tilted over and broke the microusb). I resetup things correctly with the new board, and used it for a few prints. Then just now, after doing some maintenance (I found the Z coupler got loose) I get this message after zeroing X and Z.
I did some searching, and someone pointed out that M211 should have X at 0, but the Printrbot Guide says to set it to X-25, which is what it has been.
I set it back to X =0 and it started to work. I have zero clue why. Any ideas? I thought very clearly it was supposed to be X-25.
This is what I have:

EDIT:
Well what a surprise - after Setting M212 X-0, that third Z point, just like the manual said, completely missed the bed, and the probe dug into the board. Luckily I have a PEI surface and that took most of the impact so nothing serious happened. Why can't I zero the Z axis with M212 X-25?
