Thank you, that worked!
One more question - how I can change the safety values for heaters? My chamber heater is not powerful enough to reach 1,7oC/ sec.
-
Usually running a PID auto tune on the heaters is all that's needed to resolve those errors since it gives the firmware an expectation of performance.

-
I have done that, hopefully will help.
-
Make sure you remember to use M500 to save the results to confif-override.g and add M501 to the end of config.g to load those results at startup.
-
Did that, the RRF notified me after PID tuning!
I am so amazed by the firmware!
Worth the money!

Can you share the tuned results for the chamber heater? Increasing the dead time value can sometimes help.
Share the entire config.g as well.

I am sorry for not being clear enough,

I suggest you re-run the PID turning for each heater in turn and then save the results again with M500

Silly me, I should notice that, changing that right away.
I will perform PID tuning and will paste the results here.
Btw: Should the Diagnostic LED blink all the time? I have Duet 3.
I have read that is normal but prefer to confirm -

I checked the endstops by M119, all of the are working.
Any idea what that could be?

Can that be related to M122?
When I do diagnostic it says M122 response too long, see the console.

your homing file has 2 homing passes in.
Are you saying the axis approach and back away more than twice?
