Did print fan speeds for PETG change?
I've been running the given SUNLU PETG filament configuration for weeks with no problem. I just did a PRUSA configuration update and now the print fan doesn't want to run correctly starting with the 4th layer. The fan looks like it starts to try to spin in fits and starts but then just shuts down. The print fan speed settings are 20% min and 40% max.
Fan check passes all its tests. Is it possible I have a fan going bad and it just doesn't want to run at 20%?
