Really struggling with nGen. It looks great as it goes down on the skirt, and then it just gets pulled up as it moves on to layer one. Then when it comes round again, it pulls it up again. Almost gave up. Cleaned the glass. Fresh UHU. Still no. All the time I know it's just inexperience. I try turning up the bed. Bingo. Printing now happily at 210, bed at 90 (too hot?)
I had some lifting and separating of layers, but printing at 230c and bed at 75c seems to be going well, but I did turn the fan down to max 50 which helped. The colorfabb site has lots of tips and recommended settings for different printers to give an idea of what else to change
