M503 won’t give the information I need, I think.
However, I think I can make do by knowing the X_MIN, X_MAX, Y_MIN and Y_MAX configured for the printer with the toolhead. Load up LulzBot firmware, home, and then jog as far to the left and front as you can. Record the X and Y minimum values. Then jog to the rightmost and rearmost location the axis travels to and record those values. Post those for me. I think I can compute the toolhead offset from those. Then do one more thing. Home the machine. It should stop after homing over the button. Record that position. This is what I need:
- Leftmost value of X axis
- Rearmost value of Y axis
- Rightmost value of X axis
- Frontmost value of Y axis
- X and Y right after homing when over homing button
