I am a beginner as far as 3D printing goes, but I talked my Boss into purchasing a Lulzbot Pro for prototyping. It prints PLA wonderfully, but I am having a bit of a problem when I load PVA into Extruder 2. I Have MatterHackers PVA which does run cooler than most… their site says 185 plus/minus 15 Deg. C I baked it by default when it arrived so it would be known low moisture content, and keep it in a polybox.
I have modified the Poly S1 profile for temps and the first layer adheres to the print bed beautifully the second layer starts to pull away and by the 3rd or 4th it is delaminating… Help i need support for my support.
Thanks… P.S. would provide pics, but no camera’s allowed.
