Extruder Heater and Thermocouple not working

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

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.

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

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.

; 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?

m303 h1 p1 s100 t0

This is not a valid command.

Try M303 T0 S100 That should try tuning the tool as a whole to 100c. That temp seems low though.
