doh, i used the º symbol where I meant % 
sigh - looks like it’s the filament. printed the same thing with the same settings in overture PETG, zero issues. even used sport mode/speed and it came out significantly better. i’ll try the other stuff again after a round in the filament dryer. wasted more time on this than i’d like but i’d hate to just throw the filament away.
i an printed pteg right now and i have no issue
i use iiidmax pteg and i have no issue @af0.arnau
Hi, english is not my first language so i try to explain better then i can.
I found this tread with a lot of interesting hints and explanation 
i have the new A1 + AMS Lite and trying to pring with PETG
after some failed prints and struggeling to find the cause, i reach out here for some help from you guys that have more experience then me
i noticed during the print, that every time that the nozzle lifts and drops in the new spot, on the new spot there is a littel PETG beed or littel imperfection, like there is too less of retraction during the lift, and when the head lands on the new spot there is a litte beed.
so on the next layers the the issue aplifies itself.
Can somone please help me how to fix this issue?
here is the path where the isse is
In this img is during the print, it’s difficult to see but i put some cirles to higlite the spots where the beeds are.
Thanks
Ciao

Hi @Kabal,
I mentioned it already in several other PETG posts… I have to ramp up the PETG temperature for everything except the 1st layer from 250°C to 270°C. Then the “crumbling” is completely gone for me. Just give it a try.

Thanks @darktooth
i assume that this is the correct setting to change. i will try and let you know.
@darktooth it worked perfectly! thanks a lot!
I was having a seriously hard time with PETG on my new X1C using Overture PETG. I tried these settings except I reduced the nozzle temp to 250 and it’s now printing like a dream. Thanks!!
I see no indication Ryno is discontinued. But the stock PETG generic settings appear way too hot compared to Matterhackers suggestions. I’m running a print of clear now. but it has zero challenging design elements. Just a parametric parts tray.
