PLA Rear Fan Cooling
Hi guys,
i have a strange problem with PLA printing: i start printing and after a while the rear fan turns on and decrease the nozzle temperature from 210° to 190°.
I check the Slic3r setting of the last driver and in Filament Settings -> Cooling, i have "Keep fan always on" and "Enable auto cooling" checked.
Is it right??
Shouldn't this be unchecked?
Maybe i mess around importing the new Drivers....
Thank you for your help!

Hi Robert
Rear fan? Do you mean the fan at the front? The rear fan (or side fan, the small one) should be on when the nozzle temperature goes above 50C. The front fan is controlled by Slic3r. In Slic3r you have the setting right but I would disable it for the first 3 layers and see how you get on. For ABS prints I also lower the fan to 50-60%.

Robert is using a Mk1, which has the part cooling fan at the rear.

Unfortunately, there are currently no new firmware for the Mk1. The part fan should be turned on for PLA, but try running it at a maximum of 70% for the lower part and only turn it on after the 3rd or 4th layer.

Re: PLA Rear Fan Cooling
Thx guys,
i will try with these settings:
- Keep Fan Always On --> DISABLE
- Enable auto cooling ---> ENABLE
- Fan Speed ---> min 35% max 70%
- Bridges fan speed --> 100%
- Disable Fan for the first --> 3 layers
Is it right?
