I've been trying recently to print PP with my ender 5, with a quite challenging part as it has a big flat area at the bottom, as you can see there.
The part is roughly 150x150x50 mm
So far what I can tell is :
First try was a clogged nozzle, the aspect was quite terrible and it stopped extruding after a while; I cleaned it and seems better afterwards.
Second try I had warping on the bed so I increased the temperature to 100°C
Third try seems to have warping after few millimeters, ended up clogging (again!) the nozzle, and this time I have no idea what to do
I have an Ender 5 Pro and I use Creality software and you can see the settings here
Thank you for your help !
