Thanks for the link and info sorry for being dumb i have only looked at M420 V, so want to validate a few things before i go editing stuff by hand. M420 V output is what i have been plotting in excel:
- I assume i am editing the billinear mesh (as catmull is calculated)
- The first column in the output is the left edge
- The last column in the output is the right edge
- The first row is the front of the bed
- The last row is the back of the bed
Does the M421 command use the same coordinate system?
Aka the highlighted cell is I1,J3?
Or do i have myself completely confused?
