Simplify3D users, I need some help. Im working on these bearing holders for my new printer, Im having issues with these pimples. This is the representation in simplify, but the parts come out looking exactly like this covered in pimples.
On the outside its just annoying but the inner bore its making my igus bearing undersized ovals when i press them in. What have you guys tweaked to get rid of this? Im running an e3Dv5 with an airtripper extruder.
retract 3mm, speed 3500mm/min, coast 2mm with no wipe

Did you check if your STL is without errors (gaps/missing faces)? I can try on my setup if you would like but have never seen this in Simplify. Can you show the layer at that layer height? Which version are you using?
Do you have perimeter set from outside->in, or inside->out. I go inside out, Also I find I need to oversize inside holes 0.2mm with the standard extrusion width I use in combination with 3 perimeters.
Also maybe try 4.5mm retraction.
inside out typically Ive tried both on these. Outside-in was awful. I oversize about the same typically.
Ive also started specifying extrustion width at .52 and that made a big difference. I will try longer retract tonight. I got away from it for a while because of extrusion/stripping issues, but a hotend overhaul seems to have fixed those.
Also play with the temps. Sometime a few degrees is the difference between a clean print and a sticky stringy mess.
Not in the viewer. Just on the parts when printed. I get this effect on the printed parts if I run PLA hot for speed but don’t have retraction, perimeters speed, and retract balanced according.
Could your filament be too moist? Steam would pop and sputter ruining the surface. It would look more like craters then pimples.
no this is over various rolls of filament, colors brands and most of it is either new or recently dried. There are other pictures posted above showing the rep and physical parts. They correspond almost exactly.
