Are there any mistakes in the configuration file?

@asahar best to run M98 P"config.g" and post the results

Phaedrux

Send M122 as well and post the results here.

When you say the heaters are not working, what exactly are you trying to do, and what is happening?

asahar

@Phaedrux by this I mean that I am not getting any voltage from thermocouple and heaters do not run.

Have you run this yet?

thermocouple

Are you using a thermocouple daughterboard? Are you sure it's a thermocouple?

Phaedrux

Error: M303: tool 0 does not use heater 1<LF>ok<LF>

Your tool does not have a heater defined at all. It's missing an H parameter.

@asahar said in Extruder Heater and Thermocouple not working:

; Tools
M563 P0 S"Extruder" D0 F0 ; define tool 0

Which heater are you using with the tool?

asahar

Yes I am using two thermocouple daughter boards and three T type thermocouples.

asahar

@Phaedrux yes, now I have define H1:3 with Tool 0 which is extruder. Now, I am getting this error
m303 h1 p1 s100 t0
Error: M303: heater 1 reported error 'unknown sensor' at start of auto tuning<LF>ok<LF>

What can b ethe reason?
