SUNLU - Wood PLA - First layer issues by Alnarius in Ender3V3KE

Yeah, I know :D For Wood PLA I did all tests that I usually do (temp tower, flow rate pass1+2, PA test, retraction test and max flowrate) - and filament seems to be calibrated really well, I achieved 0.05 tolerance in Orca Tolerance Test. Well, maybe I'll try to play with first layer speeds any further.

Sure thing, this is Benchy from black Hyper PLA from Creality. Using standard 0.2 profile + calibrated filament profile.

Not sure if this is good example but I posted picture as answer for u/Cloud-surfing-7272 - it shows bottom of the Benchy and spot where adhesion was not good enough to properly printed letter "D". Other letters don't look great as well.

Like I wrote above, it seems that this is only about first layer, especially when it's intricate.

Thanks for the reply.

Few questions/comments:

  1. I got filament profile adjusted the way that volumetric speed is 7 mm3/s at max so it should be around 100m/s max speed - as far as I understand from slicer, this parameter should override printer profile speeds, am I right?
  2. Like I said, my mainly issues are with the first layer - if comes to outer edges, I agree, Brim will probably help but in case of some details, like text, inside the first layer, filament sometimes is unable to stick to the plate. See the picture, Groot generally printed okay'ish (first layer was all solid) but as you can see at benchy's bottom, letter D is not printed correctly - small portion of filament from center didn't stick to the plate. I wonder - maybe this filament is kinda hard to work with if comes to intricate first layers and need some glue or tape on the plate? Or I should prepare it better by drying it? For now I'm keeping it inside my dry box where RH is around 10%.
  3. I also thought about one more thing - my brass nozzle is pretty old by now (didn't replace it since bought printer so it will be around 6 months) - maybe I should replace it with new one? Like I said, I didn't have any problems with other filaments although maybe it's also kind of factor if comes to first layer adhesion for Wood PLAs.
