Problem with A20 and Overhang

Post by Zakzak3d » Sun Nov 22, 2020 9:37 pm

Hi all,

I have a Geeetech A20 and I struggle to get out clean overhangs, I tested to print a temperature tower, but I still have the same problem, the pla is curving upwards and it doesn't matter temperature.
Do you have any leads for me to resolve this problem.
Thank you for your help !

After many try I think I have found the solution, it's look like I haven't a fan duct near the Nuzzle to cool the model, Do you know where I can found 3d model to print a fan duct for the fan :
