Well the print failed. I walked away cause it was Doing good. Come back 5 min later to a mess. Guessing it didnt adhere to the bed. Oh and I forgot to recalibrate my slicer flow rate. So got that all set and change my temps. Got a successful print so all is good now.
So I'm at 80°c on the bed.. 220°c on extruder and 25% cooling fan. The print that failed had 100% cooling fan. The baffle that I got still has stings and blobs on the inside that I have to clean out and some weirdness in the outer skin. I can't seem to figure out how to get cura to print a clean inside wall and put all the mess on the outer skin. Would make clean up way easier. Got to be a setting some place. I did change my retraction to 2mm distance and 40mm speed I think it was. Getting better with every attempt.
If I do the stringing tests. I get little to no strings, but then it goes nuts on a part. Go figure.

Have you tried hotter extruder temp? I don't have a lot of PETG experience but was running it at 240. I have a basic ender 3 with the standard bed surface (not the magnetic). I have not had adhesion problems. I do use a skirt to get things going.

stan,
I have ran hotter yes. I actually run petg at 225*c, for initial layer printing. then drop it to 220 for the rest.

OK,
My understanding was that PETG is typically a 240+ C filament. I might try some cooler prints.

Mfg label for temps on my spool of petg is 200-240°c. But now that I have replaced factory Bowden tube with Capricorn tube and now an all metal hotend. I'm playing with temps to get the best possible prints. Right now I'm having severe stringing issues on small parts. It almost seems like my Cura 4.6.2 isn't making the adjustments that I'm inputting and spitting out proper code. It runs the initial clean/purge line no issues. First 4 layers go down decent then it gets messy from there.
I had my speed down around 30-40mm/s. Then bumped up to 50mm but it doesn't seems to be picking up and still printing at the lower rate, till it comes to a top layer section then it picks up speed and cleans up, no stings until it gets a few layers in at the slow rate again.
I think I may wipe out this install of cura and do a clean reinstall, and see if that helps clear things up. Would really be nice if I could get 4.7 to work.

I'm not sure what version it is in there is a feature when the filimant is retracted but before Z is lifted it scrubbs the nozzle across the part a few mm as a wipe before moving.

Yeah, that retract swipe before z lift helps a bunch. I started with cura and then switched to slic3r (prusaslic3r actually). It just works better for me.

i think i got it figured out now. i clean installed Cura 4.6.1. reset my settings profile. now i get much better prints. I also used shortest path to hide z seam. if i use random to hide z seam i get massive stringing. should be goo to go now. still have to do a little post print clean up on the inside of the part, but it is way better than it was.
I just changed my gauntlet from 4 baffle stack in the shroud to a 5 baffle stack. seems a bit quieter yet. plus mine have a tighter clearance on the pellet as well, so i'm sure that helps.

well i about got my custom baffles done. made a set, but messed up apparently. i either clipped or they were not thick enough. blew the last 3 of the 5 apart. gun was super quiet and still accurate. made some changes and strengthened the weak points. gonna print a whole new set tomorrow and i should be good. new set is an interlocking design, so there should be no baffle shifting. doing a 5 chamber design.
had a slight issue with my nozzle leaking. got that fixed, new nozzle and all cleaned up under the sock. and i. i did notice that my expected dimensions were off again. so first i'll have to calibrate the printer again. not sure what could have caused the parts to be so far off size wise.

the redesigned baffles work awesome. this condor is whisper quiet now. well besides needing to do the hammer slap mod. all you hear is hammer and impact on target. the frame extender is louder than my custom unit. each baffle self centers in the housing and interlocks with each other, and the custom barrel adapter as well. may even sell the frame extender now. I'm quite pleased with the outcome.

Good job it really does take a while to get everything sorted but now you should not have much to mess with.
