Z_tilt vs mesh vs those fighting a flat mesh grid
..wasn't sure where to put this so figured it might help some people getting 'potato chips' as bed meshes.
Yes...oddball basis here...playing with a brand new 300 bed, but mounted in a 500 frame. (IDEX style bed support)
I'm getting GREAT repeatability on my mesh. Sub 0.1mm no problem.
I ran into something quite interesting, that is also a carry over from past Q's I've posted here trying to understand some aspects of Klipper in general.
The image below, is a screen cap of a cluster of screen caps.
Two z_tilts and what they were set to, and two 3x3 bed_mesh calibrations
You'll note the two meshes are within 0.009mm of each other.
(goes to the repeatability of the probe used itself as well)
On previous 'play times' I'd experimented with reversing the 3 z_tilt points...EG: instead of front left->rear center->front right, I swapped the z_tilt probe points to
left rear->front center->right rear. In this experiment I was trying to understand the final relationships created by the post z_tilt automated adjustments, on the mesh grid resulting from those z_tilt settings.
what is interesting, is there is some math anomalies that must exist somewhere here (and this is my Q here ... is what am I missing?)
The z_tilt adjustments made between the two sets of point configurations, does indeed result in a bed level opposite one another. Ok... that makes sense.
But the math part that intrigues me.... the z_tilt adjustments made are 1/10th the mesh grid variation, and barely approach the difference between the two meshes
(~0.009 mesh diff z_tilt variations being less in both cases)
Yes, the system was re-homed after printer.cfg edits to change the z_tilt probe points. This sequence was repeat 6 times today. What is pictured, is the worst I could get.
