SV06 PETG Cura settings

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.

CAUTION: 3mm and 6mm are WAY TOO MUCH for Sovol SV06 SV06ACE SV06+ and SV06+ ACE printers. That will cause massive failure with hot filament clogging up the extruder. Once you are done setting your slicer profile (Cura or any other) make sure the retraction distance is no more the 0.5 mm. I like to keep mine at 0.4 mm to be safe. I use the 0.5 mm for TPU.

These are direct drive printers with the heat break mounted to the bottom of the extruder. There is literately no space between them. Therefore, retraction needs to be an absolute minimum.

I agree with TheMisanthrope. 235C on the nozzle and 80C on the bed will most likely work. You can just take a PLA profile and change the temperatures to get it to work. While printing, 5C + or - incremental changes can be made to get things dialed in. Blobs mean over extrusion (too much heat) and spaces between lines in the print means under extrusion (not enough heat).

You can also bump up your print speed. I find I can easily get up to 80mm/s with PLA and PETG without suffering any print quality. However, higher speed usually requires more heat, as the filament moving faster through the nozzle has less time to heat up.

Honestly, I have migrated to PrusaSlicer an I am getting excellent results. It comes with all the profiles for all the filaments and nozzles, tuned to the SV06. The stock settings work fine, and I am able to tweak them to fit my needs easily without sacrificing quality. For me there is no need to consider any other bed slinger, and no need to do more than a few simple mods on the SV06.
