spider webs- is this normal?

spider webs

Any time i print something with more than 1 vertical part, i get LOTS of spider webs between them.

Slic3r defaults (Why?) to "dont retract unless crossing boundaries",
which I unchecked, and I'd say the problem is reduced but only by about half.

Abs at 235 with 0.5mm stock rostock extruder.
I also have "wipe on extract" and 5mm distance to extract, which seems to accomplish nada, spiderweb wise.

Is there any way to reduce this? Its not a killer, but very displeasing appearance.

maybe the hotend temp is too high and its causing some oozing? i use kisslicer, and using the suck/prime/wipe ive 99% eliminated strings. Find a small object you can print (2 cylinders) and do a test print, take note to what it does, and modify one setting in your slicer until you find the exact issue which causes this.

sorry, cross posted

the gear that's on the stepper has adjustment screw, you can move it out so the filament is placed more to your liking. it looks like your trying to push too much filament through the hotend and its chewing up the filament.

Getting rid of stringing is a bit harder, I've found, on a bowden extruder. You'll have to experiment with your retraction settings a bit. I've found that a really fast retraction speed (100-150 mm/s. Make sure your firmware or EEPROM settings don't limit the feed rate so you can't achieve these speeds) coupled with a rather long retraction distance (8-12mm) does a pretty good job. The problem with fast retraction speeds is that it doesn't give the filament enough time to compress and start extruding on time, so the first few mm's come out in small bits. As long as the first lines are made inside the object (like inner perimeters) this should mostly not be visible. If you retract too slowly, it will give the filament enough time to ooze out and leave blobs everywhere.
