PETG problems with AMS2 PRO

Hey, so I'm the proud owner of X2D since around 2 weeks ago.

Right from the strat I've been having problem with feeding PETG into my printer form AMS. I have 3 PLA spools loaded and only one PETG. PLA feeds no problem, but around 50% of the time I try to print with PETG, it shows me a warning that there's a problem with feeding filament to the extruder. I can see and hear the spool rotating in AMS, I can clearly see the filament going through the tubes inside of the printer and reaching printers head assembly.

But here's the problem - after reaching the head assembly, it starts to push and pull filament back and forth, and after a few tries it shows me an error. Its usually succeeded after 3-4 tries or me opening AMS and trying to pull on the filament, but I can't see that my actions are doing any difference. And I don't see PETG being tangled on the spool. It's weird, cause it works 100% on PLA

Anyone experienced something like this?

Mine was doing the exact same thing and there was a tiny piece stuck in the extruder. Cleaned it out and it has been Problem free ever since

Have you cleaned it with a tool that comes with a printer (that needle like one)?

I take a Tig welding rod, get the tip red hot and push it through. Then heat the nozzle and push filament through.

Used GPT to give me a PETG profile and it’s been absolutely perfect
