@oliof said in Probe deviation / calibration questions:
@whizzard just a note that Marlin 2.1.2.2 has a lot of issues fixed in 2.1. Bugfix. I would encourage you to upgrade (requires redoing config though).
I didn't know that! I will have to update and check the notes to see what was fixed.
As far as the smart effector, it works very nicely! I can't believe I can level the whole bed consistently. I have to remember to change z probe offset when the temps are different. My bed causes interference when it is active during probing, so I added gcode to heat the bed up, turn it off, probe, and then turn the bed back on after so that it is near temps during a probe.
Here is an example:
Bed 60 Celcius: 0.62 z probe offset
Bed 95 Celcius: 1.22 z probe offset
I am guessing I should just remember that thermal expansion will change my Z, but I am surprised there isn't something in Marlin or other firmware that takes this into account. Thanks again for all the help.
