What do you have in config-override.g? I think that is probably where the heater not found is coming from.

Error: Unknown pin name 'e0heat*'
Are you still getting that error? It looks like you've changed the pin name?
@antoine-voiry said in Struggling in setting up the bed compensation:
I can't manage to tweak it. Even, if I manage to get something better, it will fail in next 30 minutes with no print.
What do you mean by fail in the next 30 minutes with no print?

What do you have in your slicer start gcode?

Thanks so much!
The bed probing will be fine, and then I keep the printer on with no print and another bed level will be completely off.
I am still getting the e0heat error. In the config override, I only have the PID tune, I can post the file if needed.
I would not be surprised if I have some odd things in the config, I have been tweaking this config for at least 5 years.Here is home x

Couple things I notice
Your positioning of the probe before sending the G30 is different between homeall and homez. They should match.
In your bed.g you specify a taper height of 3mm. That may be pretty tight and can lead to les compensation then expected when printing. Try setting M376 H0 to disable taper entirely and see if it makes a difference.
Also, in our bed.g move the M561 to the start of the file before the homing calls.
The first time you start a print, it's homing, and then doing the bed mesh. The second time you start a print, the mesh is still active, then you are homing, and then you are canceling the mesh and then creating a new mesh.
I think by having the mesh active the second time you home you're throwing off your second mesh creation.

Hello
i am trying that.

I'd like to piggyback on this conversation for a moment, if you will humor me. I'm currently using mesh compensation and having pretty good results, but because of two binder clips (front left and back right) I'm missing probing of a couple of strips, leading to I think some very unfortunate interpolation in those regions.
I'd like to add some individual probe points in to cover these regions, but @Phaedrux 's comment about having the mesh active has me thinking that this isn't as simple as I would like.
Specifically I'd like to (a) cover the majority of the plate with G29, and (b) fill in a few additional spots, presumably with G30. Am I thinking about this the right way, and should I do the G30s first so that the map isn't in place, or am I overthinking it?
Thanks!
