Read chamber's temp

Aodrennn

Hi,

I use a Duet3 mini 5+ with RRF3 and I just want to read the temp inside my printer.
So I just put a thermistor at the top of the printer and I added in the config file :

M308 S2 P"temp2" Y"thermistor" T100000 B4725 A"Chamber"

But the sensor is not in "Extra" on DWC and when I send "M308 S2" the console tell me : "Error: M308: Sensor 2 does not exist"

I tried with an other thermistor but nothing new and then I try to switch the pins temp0 and temp2 and I could see the temp of the extruder on temp2.
So I assume that my gcode is wrong but I don't know what could I change.

Thanks in advance for your help !

@aodrennn Try sending the full M308 line on it's own, and see if it generates an error. Otherwise, please post your full config.g and response to M122.

@droftarts
Waw, it works now ... thank you but why i have to send the command after I wrote it in the config.g ?
Do I have to resend the command everytime I turn on my printer or it was just the first time ?

@aodrennn Send M98 P"config.g" to run config.g and report any errors. Could be there's a typo in the command in config.g, usually curly quotes used instead of straight quotes.

Here is the answer of the M98
I don't see anything bad but i'm not an expert ... tell me if ther is something wrong.
Thanks a lot

@aodrennn Nothing in there related to M308, so not sure. Did you reset the Duet after adding the M308 line?

There are a couple of other errors, though. Post your config.g and response to M115. You can cut and paste text from DWC into the forum, rather than posting images of text, btw. Format any code with the 'Code' style to aid readability, using the '</>' icon in the message composition window.

Thanks for the tip, yeah I reset my card every time I change anything in the config.g

So here is the M115 :

@aodrennn Not sure why the M308 command isn't working. The order of your config.g is a bit strange; you are defining the tool with M563 P0 D0 H1 F1 before the heater H1, and heater H1 which references temperature sensor S1 before M308 S1 is defined. Put the temperature sensor configuration first, then heater, then tool. Also move the chamber temperature configuration before the 'T0' which enables the tool; maybe that's messing with it.

Also, change:
G29 S1 ; Set Units to Millimeters (this is the bed map error)
to
G21 ; Set Units to Millimeters

and
M552 P0.0.0.0 S1 ; enable network and acquire dynamic address via DHCP
to
M552 S1 ; enable network and acquire dynamic address via DHCP
(This is the M552 error)

@droftarts
Yeah I took the config.g from the Ratrig tutorial so I didn't wrote it and I just changed with my parameters and then it worked good so I didn't search deeper.
But it's nice to can correct that now, so thank you again for your time and your help !
See you ;))
