yaman

hi all
I want to know if I can use PT100 with PT100 Daughter Board for extruder 0 tool 0 sensor
what the command I should to use
I try to use command M305 but I think this command for bed heater .
also I try to connect PT100 direct to tool 0 sensor but it give me wrong reading for temperature
so can any one tell my witch command define tool sensor

If you're having issues with making the configuration with the web based reprap configurator, try V1 instead. I ran into all sorts of trouble when trying to set up PT100 with the new.

I think I saw a thread that may have fixed the issue, but I haven't tried it myself.

But yes, I use PT100 on daughterboard for both bed and extruder.

;H0 = bed
;H1 = E0 hotend
M307 H0 B0 P1 F10 V0                                 ; 10Hz PID, ignore voltage compensation (mains powered)
M305 P0 X201                                         ; Configure thermocouple for heater 0
M143 H0 S120                                         ; Set temperature limit for heater 0 to 120C
M301 H1 S0.70                                        ; Set heater 1 PWM limit to 70%
M305 P1 X200                                         ; Configure thermocouple for heater 1
M143 H1 S280                                         ; Set temperature limit for heater 1 to 280C

Do you have two PT100 boards, or is M305 P1 X202 meant to be something else?

yes I have two PT100 boards
