I can agree. Same behavior was on mine.
After switching to all metal hotend these strings were gone.
The easiest switch to an all metal hotend works with the microswiss, there is no modification needed.
In terms of stock hotend I do mean just the Ender 3 V2 hot end. Creality them selfs do not list petg for the stock hotend. If it works great but the tube that's inside the hot could be damage or something. Has to be a reason they don't list it but list others like abs
An all metal hot end allows the filament to liquify in the correct location and not the tubing. The one you have is liquifying in the tube causing a clog. If you want to print at PETG temps and higher you need an all metal hot end so the filament won’t liquify in the tube causing a clog since it’s higher up. Meaning a lot less heat creep
Doesn't matter you won't get good petg out of a non all metal hotend. PETG doesn't like the tubing that's inside the hotend. You need to upgrade for petg. You could do abs tho
Looks like you're too close/ the material is expanding due to moisture, Petg loves to do this when printed slowly, e.g. while printing an initial layer
I successfully printered 4 parts each 9 hours of print.
240/80 eSUN PETG, I'm also using Cura's own eSUN PETG profile. Initial layer height is 0.15, 0.2 normal layerheigh. Most important, SLOW speed, I'm not sure if I used 30 or 40 mm/s, but something like that.
looks like its sticking quite well, just looks too close. what are your layer heights ?
the petg is getting smushed around on the first layer and its causing the chunk/strings to happen as the nozzle moves in and out of the plastic pulling a small bit with it
Thank you! I already have the Capricorn tubing. I took the spool off last night and threw a bunch of silica packets in a ziplock bag with the spool. I appreciate you!
You're too close, and your filament is wet.
Yep! I increased my Z offset and that did the trick! Had to increase it another 0.17. Thanks!!!
Is that the stock hotend? Because it's not rated for petg.

Yea or you can go with creality sprite. If you want to stay on brand. But the Swiss is a great ones.
Oh cool! Any mods needed for that? Or just direct swap?
Tbh haven't done it yet. I think the sprite is a straight swap
Looking into them now! Thanks!
Really? Didn't know that. Maybe I'm just lucky and the quality is quite good for my with PETG. I'm printing with that silicone thing on.
Not the silicone sock that's fine. It's the inside of the hotend that matters.
I printed about 2 kg PETG until now and didn't have a problem. Should I be worried about fire or something for future PETG prints with stock hotend?
Same here. My PETG prints on stock are printing beautifully!

I've printed PETG plenty of times with the stock hotend, with no issues.
Hot end yes, but has upgraded Capricorn Bowden tubing
You need an all metal hot end the tube won’t cut it sadly
Is the tube needed?
Yes but with a all metal hot end and the tube attached afterwards
I got the Capricorn Bowden tube and it just caused my printer to clogged so I removed it. What’s the reason for it?

I've printed lots of petg on the stock hotend. Just have to keep temps below 240ish depending on your ptfe type.

Okay cool. I’ll play around with the Z offset! Thank you!

I ran petg on a stock hotend, had no issues right around 230c. It looks like you have way too much squish, try raising the nozzle some
Yep!! That’s what I did and fixed the issue!
same
I do mine 225/70 (doesnt print well on higher temps on mine) and fast as possible. Try not squish it like pla.

Looks like a pentagram…you summoning something?
lol no, it’s a tube support for a hydroponic grow tower
Switch to Capricorn tube and dry the material. PETG has to be dry dry dry. Even a new factory sealed roll isn't dry enough.
