I have a hard time keeping temps up i made an enclosure it helped but temps can still drop while printing filament is inside enclosure,i have yet to get near ABS temps even in enclosure? hotend was about 220 tops bed was 90ish at highest temp? No idea what to do about this , before i had enclosure it was hard to even get to temp of 200 for PLA i do have climate controlled home and i keep it cool however within the enclosure temps are 83-85*C ... 15-17*C hotter then my home temp. now printer shuts down if i even try to preheat hotend i have another post asking about this problem.
