I have a roll of Nylon 6 and a roll of black ABS I'm saving for some good stuff. Both are Kodak 750 g spools. I'm going to start playing around with PTEG again. Early on when I used the stock slicer settings I had so much adhesion that I destroyed 4 build plates. I understand Z offset a bit more now, so I can hopefully play around trying to tune it without creating other problems. I'm going to start with a huge Z and sneak up on getting just enough adhesion.
