I tried your suggestion and loaded the PETG at 250C and raised it to 252-253C when starting the first print, and it actually does print now. Funnily enough, now that it loaded properly at the higher temp I could lower the temp all the way to 225C during the first print without problem. Strange since it basically refused to extrude at all at 240C at earlier tries without any signs of a clogged nozzle. Not sure why it works fine at lower temps now after loading it at a much higher temp first.
But I'm not complaining, it seems to work and I'm getting great prints out of it now. Thank you for the help!
try and load the PETG as CPE+ the nozzle gets a bit hotter, we already used this before there was an ultimaker petg profile and still do because it works.
We noticed that PETG prints better at the top end of the temperature 245 to 250 °C .
Also we noticed PETG prints better on simple Painters tape than on glass
(but I must say I use an S5 and not a UM2+ perhaps that makes a difference in printing with PETG)
