OK (I’m the same guy who posted with the petg not sticking) Before Yesterday I bought overture petg and I was deceived because I had all kinds 1f issues… But then I tried to put the bed at 90C and the nozzle at like 280 ant it worked… How come i have to print this hot 🔥?
Ok, yeah, forget the paper as far as regular leveling goes with the cr touch. Have you tried confirming your z offset since you changed the nozzle? If you haven’t, it should be fine every time you do something to the hotend.
Also make sure your heat block isn’t stripped out. I had a bitch of a time printing for a while only to discover I had overtightened my middle and stripped out the threads in the heat block. After I replaced it I had consistent good prints again.
Oh don’t worry my z offset is set tight! And for the heat block I always undertihhgened and it leaked everywhere so now I tighten it firmly but not too much to the point of stripping the block
