bloody nose, Is your printer a filament printer? Scott Yes it is. Currently I am using PLA+ filament that has a glossyer finish. Originally it was an Ender-3 V2 that had the bowden type extruder and I discovered that for small intricate printing this type of extruder, filament drive mounted on the printer frame with a long filament feeding tube to the hotend (print head) became problematic. So I upgraded to a direct drive extruder with the filament drive contained on the hotend. This upgrade essentially made it an Ender-3 S1. I am also using a 0.3mm nozzle, standard for this printer is 0.4mm but it is capable of using 0.15mm. So to anyone considering getting into 3D printing of small models I would recommend the printer they get, no matter the brand, should have a direct drive extruder. Mark

Have you tried the .15 for better detail? Too costly?

Nozzles are inexpensive depending on the material they are made of. I purchased an assortment of 5 hardened steel nozzles ranging from 0.2 to 0.8 for less than $9. Brass is the most common for low temp use with standard PLA filament and you can get a dozen for $10. Yes smaller nozzles give better detail but at a cost of print time. I am a newbie at this so what I have learned so far is that min and max layer thickness should be about 30% and 75% of nozzle size and line width should be 100% to 150% of nozzle size. So with a .3 nozzle I can go as thin as .1mm which is about the same thickness as a sheet of 24lb paper! I have experimented around and layer thickness of .15 to .2 gives pretty good quality and I usually use .3 line width. Although I did try .25 width and it seemed to work ok. Temperature is another factor, the filament I am using requires 205° to 225° centigrade so getting the right temp for a particular type of print can take some trial and error... All of these values are set in the slicing software when creating the G-code file that is sent to the printer. For now I plan on staying with the .3 nozzle until I get more experienced.
