E3D and PETG

I am really struggling to get the results I want from PETG using an all metal hot end. I just cannot get the stringing down to any form of acceptable level. I have tried increasing retraction but can only go so far without clogging my heatbreak.

Can any offer some advice for this? I am pooped

Below is my exported profile, ignore the other material types, and i've attached an image of the issue

First bit of advise, stop with the all metal hotend, that's most likely whats holding you back.

All metal heatbreaks are designed for high temp filaments, higher than ABS, talking like nylon etc think 250c or higher.

Below that they can be a detriment, especially with stringy filaments. By going with the heat brake type that runs the PTFE tube all the way down to the tip your much less likely to have issues with retractions with PETG.

Print slowly PETG does not like going fast.. I use slow print speed of 30mms and fast non print moves to reduce stringing.
I cant seem to figure out your print speed or temp from that export there....
I print first layer at 235c or so and then drop to 220c but those numbers may be out by a bit as my thermistor is shitty

looking at your pic, your too hot IMO....

You'l need to find the correct combination. That could take a while printing with PETG.
Retraction is a very important issue.
I would lower temp a bit. You need more retraction and indeed no fast printing.
Another possibility is changing brand. I had the same problem a long time ago, changed brand, problem gone...

PETG
nozzle 0.4
I always use all metal hotends.
print temp 240°C
Bed 75°C
retraction 1.3mm
Printspeed 60mm/s
partscooling 35%
And again, not all brands will give the same result...!!

justsumguy, Yes I have come to that same conclusion myself. The all metal hotend is limiting my ability to perform a good amount of retraction required for this material. I have since purchased some capricorn XS tube and a 4.1mm inside diameter heatbreak.

Thanks for the advice though guys. It has pretty much confirmed my hunch for the last week or so trying to hone down the settings for this stuff
