As you know, chamber fan turns on @ 32C by default, I find this very annoying and I have to rush every time (e.g. after a reboot, with the printer warm) to set the chamber fan temperature to a setting that will turn off the annoying fan.
The fix is very simple, and it’s hidden, as usual, inside printer.cfg:
Just change the 32 value after “target_temp” that I have highlighted above, to one not higher than 80 (else it won’t be accepted by the printer at the next reboot and it will ask you to correct it). For safety reasons, I suggest to not go higher than 60 anyway.
