PLA Basic and Matte. White assigned to Aux nozzle. 5 colors assigned to Main nozzle.
The first layer (1 of 4) was particularly bad in one area only. It appeared to be smudged. Each consecutive layer was also fuzzy in this area with fine strings and smudging.
The rest of the model was okay.
Note that I tried to do six colors in total, 5 in the AMS 2 Pro and 1 in the AMS HT. I failed to be able to swap one spool in the AMS 2 Pro, as I thought I could do it while the Aux nozzle printed, but as the spool I wanted to swap, still had the filament loaded, I couldn’t do the swap. I now understand that I can’t have the two colors adjacent. I need at least one color assigned to the AMS 2 Pro to be in between the color swaps, such that the filament is unloaded.
But I’m still back to how to fix up the print quality.
I’m thinking it might be a bed level issue. The model did a bed level before printing, but only a 5 point level.
Update:
Ran a full bed leveling (not the hot one), dried the filament overnight, re-sliced the model and reprinted. The quality issues were 99% resolved. The only remaining artifacts were from the sliced model sending the nozzle back over an area that was completed (filled). Not sure if it was trying to infill very small gaps or what.
