Heater fault when extruder start.
-
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 M307 H1 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit

@eRick could well be interference from the motor cables.
Does the PT100 cables run in the same bundle as the motor?

Yes, but on my old configuration he worked correctly.

@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.

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

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

@eRick that would certainly reduce things but I think a shielded cable for the PT100 is also a good idea

Ok thanks.
