P2S won’t feed PEBA - I have tried everything, Dried the Sainsmart 90A for 2 days, changed the nozzle to a .6, Cut the filament at a sharp angle, preheated the nozzle and manually directly fed from the top and it just won’t feed. It grabs and lowers when I push the button to feed but stops at the head. Seems like I have clogged 2 heads a .4 and .6. I just couldn’t print with PLA in those heads. I swapped to a new .4 and the PLA loaded np. Also TPU feeds np I made a airless basketball that didn’t bounce very well. Please give me some suggestions.
