Good morning!
Do you know why the new Sovol 08 update came with the front print-cooling fan disabled?
[fan_generic fan1]
pin: extra_mcu:PB1 # front model cooling fan
To make it work, it needs to be:
[fan_generic fan1]
pin: extra_mcu:PB0 # front model cooling fan
Could making this change affect the print head’s operation?
Hi,

We haven’t disabled the front print fan; the fact that PB1 isn’t working suggests the fan is connected to the wrong port. Please revert your configuration file to its original state, then refer to the image below and connect the fan to the port marked with the red arrow.
