[solved] Extremely long wait after prime blob
My printer stops at position shown in image when starting a print after prime blob. Hotend temperature is moving up and down 1 degree above or lower than set temperature. I have changed thermistor and I have done PID tuning.

Slicer start configuration issue, happens if you don't insert heater commands before START_PRINT (or disable them). Check the slicer section in the RatOS docs. Prusa slicer 2.6 has an option to disable outputting heater commands, you can check those instead of manually entering M109 S0 etc.
It only happens after I changed thermistor. It wants to wait for the temperature to settle, but the temperature would drift 1 degrees up and down. I would like to know if there is a way for it to not check heater after prime blob
There is, i just told you how 😄
Your problem is that the slicer is inserting heater commands at the start of the gcode file
Follow the documentation, or check the box as i mentioned, and that goes away.
The only way is PrusaSlicer? Will it be possible on SuperSlicer or Orca Slicer?
No, it's possible in all slicers. Either they have a box or you simply insert them before START_PRINT in the custom start gcode yourself. Again, just follow the ratos slicer documentation and it's taken care of.
I don't remember if Orca has a box or it's enough just to set the gcode flavor to klipper.
SuperSlicer behaves the same as PrusaSlicer, and also has a box you can check to stop outputting commands.
Got it, I'll have a try, thank you
It looks like after I did that my extrusion is broken, the first line will print fine, then extruder retracts all that out when turning the corner. There is supposed to be no retraction there. This is very odd, never seen this before
Make sure to set the relative extrusion macro parameter in printer.cfg so it matches your slicer setting. SS no longer outputs the gcode to set it after you checked the box (always hated this implementation).
All this is taken care of in the RR profiles that ship with SS btw.
Thanks. I used the RR profile for SS a year ago and it's probably very outdated now. I will try updating to the new profile
