I’m having stringy problems when I move from printing one star to another star in the attached pictures, I have retraction ON as you can see from the spreadsheet. I would really appreciate some help. I have attach pictures and spreadsheets of what my setting are. I am using a Lulzbot TAZ 5 Cura 3.6.20 Matterhatter PETG filament (white) ---

Hi there, I’m no expert however I have had good results printing with PETG. I assume your filament is dry, right? Looking at the pictures, it appears that your Z-offset is too high. I see spaces around the perimeters at the starts and the stringing between stars may be caused because of lack of adhesion. If it were me, I might try a test print with a thicker layer height like .25mm or .30mm and do a live Z adjustment while printing the first layer. You using a 0.4mm nozzle? Good luck. -Mike ---

Thanks for your response. The filament is dry, I keep it in a special container that keeps the humidity out. I am using a .4mm nozzle I will try out what you suggest and let you know the results **Are you printing with a TAZ 5** ---

I have a TAZ6. It is my first printer and bought it 2 years ago which means I have 2 years experience in 3D printing. PETG does tend to string somewhat. I’ve printed at 240°c and also have printed at 235°c with good luck. FWIW, here’s my first post on this forum where interestingly enough I reached out to the community with my PETG first layer issue. -Mike > [@TAZ6 - PETG first layer issue](https://forum.lulzbot.com/t/taz6-petg-first-layer-issue/22645): > > Not sure if this is a Z-offset issue or a bed level issue, or a bed flatness issue. I’m attempting to print a large spiral and the first layer appears quite good except in two areas. The upper right portion of the bed has a slight issue and the lower left is terrible where the filament is either not adhering properly or something else. The bed was cleaned with iso-alcohol and a thin coat of glue stick applied. Nozzle temp is 235c and bed temp is 80c. First pic is upper right, 2nd pic lower left… ---

PETG is a PITA when it comes to stringing. For me it helped to increase retract untill the stringing was near non-existent. I could never make it disappear though.
