Had the UM2 for a 2 weeks now, prints like a beast with PLA. No feed issues at all.
I did some research and it seems that most are printing XT at 235 degrees (or less) at 50mm or so. At 235 the XT is worthless, at 220 it won't extrude; however, 245 is money for me.
The main issue I have is base plate adhesion. It simply will not stick to the base cold, if it does it will warp super quick. I can't print on a base under 80 degrees. Is this normal? So far I'm having luck with an 87 degree base but I feel lucky that all the prints have come out fine. If I look at the print the wrong way it will come off the baseplate. So far I've tried the glue stick that came with the UM and some watered down wood glue. Additionally I tried smoothing the gluestick glue over with a wet paper towel. Should I be trying another gluestick brand? Hairspray urks me a bit because of all the particles flying all over the machine, but I'll try that if need-be.
Did I get a bad roll or is it me?
