[[Wanhao i3] PLA filament tangled/knotted around the motor... Hardware problem? Cura Settings?]

It is 1.75 indeed! I actually don't know what's the base layer speed but I'll try to play with that parameter tonight, thank you very much.

I already tried changing printing temps but it didn't change anything sadly

Cheers ;-)

Thank you very much for your reply buddy ;-)

Normally the printing speed is the same, and is very low (around 30mm/s). Also, I use PLA, but don't to which extent you can consider it flexible, but I think it is not, if you bend it too much it will break.

This is the one I use: https://www.amazon.co.uk/PrimaValue-PLA-Filament-1-75mm-Various/dp/B013K82E7K

This problem happened one or two times during the real model printing, but it happened way more during the printing of the base layer.

Hi everybody,

I've been using a Wanhao Duplicator i3 with Cura for a while now, but I switched to the old cura software to the new one a month ago. It has been long to find the good parameters to have clean prints, but it seemed to work for a few print.

Without any changes, all my prints then began to fail, because the filament gets tangled around the motor. I wonder if there is not a cooling problem from the front fan that is supposed to cool the motor.. The temperature would then increase in that pseudo-chamber where the filament gets entrained by the motor.

I'm printing with PLA at 210°C, with a heated bed at 50°C.

Here is a picture of what is happening:

Do you guys know a solution to that problem? Thank you very much ;-)
