BLTouch enabled Ender 3 w/4.2.2 board running mriscoc's Professional firmware.

How is it that the auto tramming can report the corners of the bed to be level, and then immediately afterwards it produces this mesh?

What am I missing?

  • $\begingroup$ Still, other than a bug in the firmware, why would it do this? Am I misunderstanding tramming vs leveling? $\endgroup$ Jul 26, 2022 at 8:55
  • $\begingroup$ Leveling is making the print bed parallel with the earth. Tramming is adjusting the print bed to be parallel with the XY-axis. (hope I got that right) $\endgroup$

    $\begingroup$ Have you asked on the Github's discussion page about this issue? Since this is their area of expertise they may have a better idea about what the problem is. $\endgroup$

  • $\begingroup$ @agarza Leveling or tramming is explained in How do you level (or tram) your build surface correctly?. $\endgroup$
