I'm trying out colorfabb nGen copoly on R2. I use Cura as my slicer. I was wondering if there were any general tips someone might have for this filament. I've noticed it seems to stick harder than PLA and is very brittle. When using a raft and removing it via a print removal tool generally just a piece of the raft will break off instead of the entire structure. Will a glue stick help this? I'm printing it with these settings (most are consistent with colorfabbs reccomendations) 230 C/ 75C Fan: 50% Retraction 2mm Retraction speed: 45 Print speed: 50 I'm wondering if this is an oozier filament and I should modify the flow rate? Any tips someone might have would be appreciated.
