Variable not matching my printerconfig

[lorangthierry]

Hi,
I have to replace in mmu_form_tip.cfg the line
{% set orig_fan_speed = printer.fan.speed %}
with
{% set orig_fan_speed = printer['output_pin fan0'].value %}

If not I have a firmware crash when I change the temperature for tip forming.
For an update I have to reset the Git Repo and after the Update I have to redo the changes.
Can I define the printer.fan.speed somewhere else so that I have not to change the read-only file?

you can create a copy, rename and modify the tip forming macro to suit.
Set form_tip_macro in mmu_parameters.cfg to the new name of your tip forming macro.

Is also a possibility. I think it is easier to change the file after the update. So I don't have to check the original and my version to differences.

@lorangthierry What version of Klipper are you running on. printer.fan.speed is one of the documented ones. Perhaps you can share the fan configuration in your printer.cfg so I can see how it is set up...

printer.cfg.txt
Here my printer.cfg.
It is a stock Qidi X-Plus3 with Klipper v0.12.0-404-g80d185c9
Maybe the fans are wrong defined in the printer.cfg.
The cfg was downloaded from https://github.com/leadustin
