Here is a comparison between an old benchy done with my Ender-3 and three with the SV-08

Thanks for the lead! That might be it, I saw a big blob of goop leaking from it the first time I heated it. I’ll rebuild the hotend when I have time. There an extra nozzle in the kit.

Edit:

Here is a comparison between an old benchy done with my Ender-3 and three with the SV-08. The surface finish with the Ender 3 is much more consistent and the PETG is a lot shinier. Maybe speed is a factor too. Shoud I try and slow the SV08 down a notch?

Nice cheat sheet!

Weirdly enough, I printed at 235 thinking the nozzle was too hot and it was worse. At 245 more issues seem to disappear except less than ideal overhangs.
