Add a chamber's temperature attribute to the filament class

[Flob74]

Hello,
I really like this module for filament's management. Congratulation for your work.

I got a Voron 2.4 equiped with a Mellow fly SB2040 which include a chamber temperature sensor. I use M104 M140 modified with klipper filament_extra and :
TEMPERATURE_WAIT SENSOR="temperature_sensor chamber" MINIMUM={printer.extruder.filament.chamber}
to heat the frame before calibrating. Tipically, extruder : 250°C, bed : 110°C and chamber : 45°C.

As you can see in the following txt file (which is a renamed .py file), I slightly modified your python code to add a chamber attribute that can be modified like the bed temperature. And... I rearrange the QUERY_FILAMENT messages to print everything in on statement.

filaments.txt

I consider that if it is working and usefull for me it could be so for someone else. And maybe someday, moonraker will report my klipper_filament_extra from "different" to "up to date".

Thank you.

Thanks for giving it a try and for the feedback @Flob74!

I think this is a failure of my documentation, which is my fault. SETUP_FILAMENT actually supports saving custom key value pairs out of the box:

SETUP_FILAMENT NAME=PLA EXTRUDER=220 BED=65 CHAMBERTEMP=50

That actually works and can be read back from the filament object:

{printer.extruder.filament.chambertemp}

You can specify any number of custom keys and they can be number, strings of whole objects if you want.

Lets keep this issue open and get the documentation updated. Maybe also the SETUP_FILAMENT command should print the extra values that were saved? What do you think?
