I will try separate motor cable from heater cable.

God damn, it work. @jay_s_uk thanks for help :3

Ok thanks.

@jay_s_uk
When I will replace extruder cable on shielded cable then that will it helps?

@eRick you'll have to elaborate a bit more on what your old configuration was

He was same but wichout covers and with old firmware.

I will try separate motor cable from heater cable.

Does the PT100 cables run in the same bundle as the motor?

Yes, but on my old configuration he worked correctly.

Hello,
Every time when i start extrusion, heater have fallout (2000 C). On cold extrusion too. I use PT100. What could be causing this?

;--- Heaters
M308 S0 P"bedtemp" Y"thermistor" A"Bed" T100000 B4138	; configure sensor 0 as thermistor on pin bedtemp
M950 H0 C"bedheat" T0									; create bed heater output on bedheat and map it to sensor 0
M307 H0 B0 S1.00										; disable bang-bang mode for the bed heater and set PWM limit
M140 H0													; map heated bed to heater 0
M143 H0 S120											; set temperature limit for heater 0 to 120C
M308 S1 P"spi.cs1" Y"rtd-max31865" A"Extruder"			; configure sensor 1 as thermocouple via CS pin spi.cs1
M950 H1 C"e0heat" T1									; create nozzle heater output on e0heat and map it to sensor 1

@Phaedrux
Does the print quality change when you change the steping from x256 to x16 with interpolation?

Ok thanks

@Phaedrux said in Extruder motor not working correct.:

Did you try any of the other things I mentioned?

Yes, I change motors on x16 stepping with interpolation.

Goooood damn, it's working, thank you, you my hero :3

@Phaedrux
I heve one question.
Why stepping with interpolation is beter?

@Phaedrux said in Extruder motor not working correct.:

Second, you only have a single extruder defined in M584, but you are specifying parameters for two extruders in your other settings. So remove the second extruder values for M92, M566, M203, M201, M906

Second extruder is for auto bed leveling.

Updating doesn't help.
