@sm180 said in Duet 0.6 temp problem:

@droftarts My Duet appears like a "1k ohm" type - resistor R21 and R19 are marked "01b".

....so I have to change the R4700 value! For 1k ohm Duet is it "R1000"?

Ok, I put "R1000" in config.g and..... IT WORKS!!!!
Thanks to the forum and nice printing !

@dc42 I'm not sure about the previsious version, pherhaps 1.21....; this is my config.g (I try to change the thermistore value with 3950, but nothing changes)
config.g

@phaedrux Unfortunatly I didn't save my old config file, so I can't verify the old configuration solves the problem.....
No other changes was made.

Hello and excuse me for my poor english (I write from Italy).
I have a problem with my old Ormerod 2 (528.2), equiped with a Duet 0.6: I finally decided to update firmware (now 1.26.1) and web interface (1.22.6)..... but when I restarted the printer, bed and hotend show 2000° (open circuit) !
I test the thermistors (both values are 122k) and also wires appear ok. Pheraps a bad config.g or a vssa fuse problem?
This is my config heaters section:

; Heaters
M305 P0 T10000 B3988 R4700 ; set thermistor + ADC parameters for heater 0
M143 H0 S120 ; set temperature limit for heater 0 to 120C
M305 P1 T100000 B4138 R4700 ; set thermistor + ADC parameters for heater 1
M143 H1 S280 ; set temperature limit for heater 1 to 280C

Thanks
