jerey it can definitely be too much squeeze tension on the drive. there can be enough pressure there to squish the filament into a wide oval shape which will get tight in the filament path. just put enough tension to leave light teeth marks in the filament.
griff, fwiw i have printed atleast 30 spools of the esun petg without a single clog or issue so there is something going on with how you have it set up. its super consistent. madesolid is good as well just expensive and the opaque doesnt layer bond well at all. thin walls will pull apart. they are 2 different animals though. not the same type of plastic.

What temp do you run the blue PETG at?Re: esun petg
245-255. i attached my profile for it. keep in mind i am running an e3d hot end so take the profile and set your nozzle dia and width to auto. measure your filament and be sure that is set correctly. this should get you really close with only some fine tuning needed. if you are still having trouble then your bed gap isnt right or your overextruding. double check you dont have too much tension on the filament like i said in my previous post. since your having trouble on layer 1 though, like i have said before your bed gap isnt right.
Re: esun petg
I was having massive clog issues on my all-metal v4 and esun PETG. A few changes have cleared it right up.
First, I got another PTFE lined extruder and used that instead. If you are using a PTFE lined extruder, make sure it is actually PTFE lined. Mine managed to arrive with neither liner nor cap screw....
Second, make sure you are printing slower than you would with PLA. 50-60 mm/s should do it. Increase your infill to 130%, but not much over that. Or 100% with one of the new every-layer infill patterns in S3D.

What kind of bed gap are you starting with? I am using .13mm and I feel like I have to increase First Layer height to at least 150%+ so that the nozzle doesn't clog. The .13mm gap works great for ABS when I run that.
Re: esun petg
if your in s3d and you increasing the first layer height your doing nothing because when you use that setting it also increases the plastic flow. if your are wanting to increase your gap via the software you need to goto to gcode tab and enter an offset for the z axis. remember all those first layer settings also change plastic flow to compensate. here is a link to something i made a long time ago to help with this. remember that when the first layer extrudes each line should just touch. they should not be super flat or squished together.

Re: esun petg
Petg is the filament that will teach you how your printer should be set. I learned a lot from getting this to run correctly. I thought I had good settings and first layer heights z gap and bed level. I was wrong. After you truly dial in your printer your first layer will look better than your top layer after you pull it from the print bed. Totally worth it.in the end . 
Re: esun petg
I was having quite a bit of trouble with PETG and jamming and finally narrowed down my problem.
Now that I changed from one fan to two, I'm printing with no problems.

Re: esun petg
hmmm yeah i think jin said those noctura fans dont move much air. thats a damn nice fan guard on the top though! 
Re: esun petg
What is the purpose of Layer Width then? If the Layer Height automatically changes amount of plastic what does the Width adjustment do?jimc wrote:if your in s3d and you increasing the first layer height your doing nothing because when you use that setting it also increases the plastic flow. if your are wanting to increase your gap via the software you need to goto to gcode tab and enter an offset for the z axis. remember all those first layer settings also change plastic flow to compensate. here is a link to something i made a long time ago to help with this. remember that when the first layer extrudes each line should just touch. they should not be super flat or squished together.
