mesh bed compensation not applying correct corrections
-
@Veti just ran though a 3x3 grid to check and i am consistently getting 2.31 for the trigger height

Current reading 0, threshold 25, trigger height 2.31, offsets X-29.5 Y11.4 -

does that macro do this?

@Veti ive wrote it as this to probe 3 times per spot:
G1 Z10
G30 S-1
G1 Z10
G30 S-1
G1 Z10
G30 S-1 -
so have just run it again and i am getting quite a large variance now in the region of 0.11mm is this a mechanical issue? the machine is set up on linear rails and i have ensured that they are as square and parallel as possible

G30 S-1that determines repeatability, but does not determine z probe trigger height as you do not determine z=0 before probing as described in the above linked document
-
@Veti so do i have to go though the full calibration procedure for each point that i probe on the bed?
-
@necrorat
do one at the point where the lines where ok and one where the lines where not ok -
@Veti so just did a test over 5 point and theses are the results :
2.064
2.068
2.066
2.059
2.046 -
thats a lot different than your original trigger height of 2.31
-
@Veti i have been tinkering with the frame and alignment all day. gonna probe the bed one last time then try another print
-
Sry to bring up that old post again.
@necrorat Did you find a solution or the reason why the meshbed compensation didn't apply?
I have the same issue.
