Does anyone have a solid Cura profile for printing PETG? I’ve been printing the overhang test and getting pretty awful results. Lots of sagging and blobbing.
I just joined today and saw your post.
I run PETG exclusively and have found that the stock cura settings are perfect. The only changes needed are to the printing and bed temperatures.
I print mine at starting temperature of 235C on the nozzle and 80C on the bed.
After the first layer goes down, I have the temperature set to drop down to 230C on the nozzle and 70C on the bed.
have you ever adjusted the retraction settings?
PETG is prone to stringing due to high printing temperatures, For direct drive extruders, the retraction distance is suggested to be 3mm, and for Bowden extruders, it’s 6mm. The retraction speed is suggested to be 25mm/s. Also, you can try enabling Combing and set it to “Within infill” to reduce stringing.
