Recently my boss got a UM2+ for work projects, and we have been printing things recently in PLA, just kind of getting a feel for the printer and how it prints and works and such. Today we tried going to printing ABS on the printer, but I cant seem to get the prints to stick to the build plate. I am using a brim, and an adhesion modifier called wolfbite. We have had good luck with wolfbite on our previous printers.
As the print was going, I was watching the buildplate temperature, and noticed that 1) it takes a long time to get to our desired build plate temp of 110C (We have had good success using this temp with our filament and getting prints to stay down), and 2) when the printer does get going after taking forever to warm the plate, it doesnt seem to hold that temp. It slowly works it way down to about 85C and just hangs out there, and then the filament shrinks and curls off of the bed till it comes off.
Is there a reason it takes forever to get hot, and why it wont seem to hold the temperature? I cant sent the build temp in cura when i select the UM2+, so I have to manually set it once I start the print. Is there a setting somewhere that I dont know about?
