heaters above 305c

rexx

Hi all i have tried looking for a bit on how to get to 400c with pt1000
its working now up to 305 after that limit setpoint is not updating afer this last line is added

; Heaters
M305 P0 T100000 B3950 C0 R4700 ; Set thermistor + ADC parameters for heater 0
M143 H0 S125 ; Set temperature limit for heater 0 to 125C
M305 P1 T100000 B4725 C7.060000e-8 R4700 ; Set thermistor + ADC parameters for heater 1
M143 H1 S350 ; Set temperature limit for heater 1 to 350C

350 c does not take either
others have had this issue but I cant find the fix....

Can you post your full config.g?
What firmware version are you using?
What exactly isn't working?

Your M305 is for a thermistor, but you say you're using a PT1000?

@phaedrux weird 305 are wrong then i have a slice pt1000 and 50w 24v heater but my config now shows different from what i showed you ....not sure why yet still looking into either way this is the config.g

@phaedrux the new temps cannot be used i can only go to 305c

@phaedrux
ok its working now i guess it never completed something but i have temp control
i should be good thanks for reaching out

@phaedrux also congrats on the IDEX 22 sporting a duet 2
