Putting the heater into operation what is wrong?

dieterdd

I have tried to understand the existing Gcode. The hotend has been set to "out3" and "temp3" by the creator. I have connected both heater and thermistor accordingly.

But when I set the temperatures in the controller at tool 0 and switched them on, the temperatures shot up above the set values.

As feared I need your help again

For info: the other two heaters are used for the bed (50x50cm each)

Board: Duet 3 Mainboard 6HC

; Heaters
M308 S0 P"temp0" Y"thermistor" T100000 B3950 ; configure sensor 0 as thermistor on pin temp0
M950 H0 C"out2" T0 Q1 ; create heater output on out0 and map it to sensor 0 ; disable bang-bang mode for heater and set PWM limit
M143 H0 S70 ; set temperature limit for heater 0 to 70C
M140 P1 H0

M308 S1 P"temp1" Y"thermistor" T100000 B4138 ; configure sensor 1 as thermistor on pin temp1
M950 H1 C"out1" T1 Q1 ; create heater output on out1 and map it to sensor 1 ; disable bang-bang mode for the bed heater and set PWM limit
M143 H1 S70 ; set temperature limit for heater 1 to 70C
M140 P2 H1

M308 S2 P"temp3" Y"thermistor" T100000 B3950 ; configure sensor 1 as thermistor on pin temp1
M950 H2 C"out3" T2 Q500 ; create heater output on out1 and map it to sensor 1 ; disable bang-bang mode for the bed heater and set PWM limit
M143 H2 S260 ; set temperature limit for heater 1 to 70C

M307 H0 A200.8 C850.6 D2.0 S1.00 V24.0 B0
M307 H1 A200.0 C850.0 D2.0 S1.00 V24.0 B0
M307 H2 A491.0 C185.5.0 D4.9 S1.00 V24.0 B0

to the picture:The going down of the temperature was done by "hand"
Thanks for looking at it in advance

Did the temperature really rise 200c in less than 30 seconds?

Can you plese provide some more details?

What kind of heaters (12v? 24v?) and thermistors are these?

Can you please post your full config.g?

Also the results of M122 and M98 P"config.g" can be very useful.

Never think to have thought, because thinking the thoughts (I would have used a 24V heater) is thoughtless thinking ... it was a 12v heater cartridge thank you! danke!
