[RafB]

it's glass

[Phaedrux]

That height map would indicate a possible mechanical problem. Perhaps something is misaligned or bent.

How fast are you probing?

[RafB]

No, I do not think I have a mechanical problem.

Look at this bug when I run "auto delta calibration" I have this result.

But when I do "run mesh grid compensation", j'ai ce résultat.

This error message G29

D'ou vient le problème?

[Phaedrux]

What are you using for your deployprobe.g and retractprobe.g macros?

@rafb and how are you deploying and retracting in your bed.g? Are you manually calling it in your homing files or letting g30 handle it?

Are you manually calling it in your homing files or letting g30 handle it?
I do not know and do not understand

I do not find why I have this problem. I will start from scratch.

this bltouch seems not to be the best sensor for Duet

[Phaedrux]

How do you have it wired?

Does it light up at all?

Can you send the servo commands to deploy and retract it?

[RafB]

the bltouch works great.
