If you are stringing with PETG, then I would suggest turning down or off the cooling fan in the nozzle and running the filament at the top recommended temp you can, it needs those high temps to properly melt and mesh with the other layer lines. Also, slow the print down if you can, but turn up the travel if possible so it has less time to sting up while moving from one side to the other. Also you might mess with the flow rate, if it's too high, it can cause stringing with PETG.
Not sure what printer you are running. This is what I had to do with my Ender 3's. I haven't had any issues (or VERY FEW) issues with stringing with my BambuLab A1 and A1 Mini. But aside from a different printer, figuring out the PETG stinging thing is one for the ages, lol.
I have the K1C. I've turned off the other fans but will give the nozzle fan a try. I've been running PETG at 260C on a flow of 1.0 and it's mainly stringing on gaps or overhangs. I had "slow for overhangs" on the first basket and it had a lot of strings but I turned it off on the second and it was way worse so likely right the speed is a big factor. I've really only had this problem with the White PETG, the other colors haven't had this much of a problem using the same settings.
I found that it didn't matter the color, at least for me, just the design of the piece. That could be with your filament too. I have found that since I changed brands, I don't get near the stringing. I use Kingroon PETG and haven't had any issues.
Actually the only stringing issues I have had as of late has been on TPU, but I am still learning how to work with that wet spaghetti noodle stuff, lol.
I'm trying higher travel speed now on hex inserts to see if it helps. Have to try 1 setting at a time so I don't muddy the waters too much. It's Creality PETG for this spool which could also be an older one. Other brands of white haven't done this as bad. And yeah it is seeming mainly the design, ones that are mesh or honeycombed seem worst.
I've got rolls of TPU and TPR sitting in my cabinet but I've been a bit leery about trying it out yet. It sounds like it's not the easiest to work with.
AH Creality... I absolutely HATE their filament, lol. Also make sure it is as dry as possible...
I only run my filament out of my dryer to make sure it's dry. Yeah I've been having better luck with lots of other brands, this is one of my first spools I got with the printer.
Yeah, use what you have for sure. Especially if it is just for personal use.
So I set the flow to .95, set travel to 1000, then dropped all the layer speeds about 25% and it's looking much better now. No strings at all on this dummy 13 armor print. Thanks for the help!
