I've been trying to fix this exact issue since I bought S3D last week.
It's a great slicer (pre-configured settings are doing fine, supports are amazing), except that I noticed this same issue now.
I'll keep it short and share my Facebook post that I made a few days ago. I actually came to S3D forums because nobody responded to my post on Facebook, thought I should give S3D forum a shot.
Then I log in here, click on "Troubleshooting and Bug Reports", see this post at top, click on it (because the title looks similar), aaand . I even tried to remember if I posted here previously but forgot, yet the user name is different so it should be someone else having the same issue .
Anyway, here is my post from Facebook;
Hi there, first post in group! And appreciate the help! Please let me know if there are any specific rules that I should follow before posting (other than being kind to each other).
This problem only occurs with S3D, printing the same STL on Cura (with default settings) is perfectly fine (so I think it shouldn't be hardware related). I use the default (pre-configured) profile for my printer (CR-10) both on Cura and S3D.
Have also read a lot (guides on S3D's site, FAQs etc., and also searched the web for it), tweaked a lot of settings, like;
- Slowing the speed to half (30 mm/s)
- Setting "extra retraction at start" to negative values (as far as -0.5 mm)
- Playing with extrusion rate (1.00 to 0.85)
- Playing with "coasting", "wiping", "z-hop", other retraction settings, etc.
- Actually a lot more, just can't remember all of them but just ask if I tried something and I can tell if I did or not, with which values, etc.
...yet none seems to help.
What I noticed was that those small defects at some corners always happen when the nozzle starts extruding at that point after performing a retraction previously on somewhere else. So, I didn't try vase mode, but it should eliminate them, yet I won't be able to print anyting solid with that.
Will appreciate any kind of help! Thank you!
