I've been printing for a week now on my new printer and have been getting great results, including great adhesion. However, most of my prints have had a fairly small footprint.
Now, I'm stepping up the types of items I'm printing, and I've started to run into a problem. Long, thin parts are starting to lift off the bed, especially at the edges of the bed.
I've read the question dealing with this issue with ABS and realize some (most) could apply to me. However, I'm printing entirely in PLA on a non-heated bed.
My question is: What is the best way to go about troubleshooting this problem? In which order should I attempt fixes to narrow down the problem most quickly?
Printer: Monoprice Maker Architect 3D (Very similar to Makerbot)
Heated Bed: No
Bed Material: Something similar to BuildTak on top of an acrylic bed. (The sheet of material came unlabeled with the printer and I haven't been able to track down exactly what it is.)
