I recently brought an ender 5, I started printing off with the white plastic that came with it. It worked perfectly, until I ran out. So I wanted to print an rc boat and thought ABS would be a better material to printing it with. So I bought a roll of Abs. But I am having a lot of issues with it. 1, it doesn't stick to the bed properly, I've tried cleaning it with methonol, re-leveling it, but nothing worked. Then I used hairspray on the mat, the filament stuck! I thought I have finally overcome my problems, then came warping. I can't stop he warping!! So if anyone has any tips on how to print with abs PROPERLY, please let me know.
