Topic: 1 print working assembly

This was actually 14 separate pieces, 12 roller bearings, outer race & inner race. After removing the hair like support remnants the rollers actually roll on the inner shaft albeit with more travel than would be in an actual bearing but it does display real world parts for me prototype application.

I'm no expert, but that "hair like support" doesn't look like support at all, but rather stringing. You need some retract!

Yeah.. What Professor X said.  You need to implement or increase your retration between moves, you might also want to reduce your flow rate.

Did you ever run the calibration tests?

To print or, 3D print, that is the question...
SD3 printer w/too many mods,  Printrbot Simple Maker Ed.,  FormLabs Form 1+
AnyCubic Photon, Shining 3D EinScan-S & Atlas 3D scanners...
...and too much time on my hands.

Re: 1 print working assembly

I don't think that is stringing from retract settings.... looks more like a bonding issue where certain extrusions get pulled away from where they were laid... this can happen depending on the design and is amplified if your layer/extrusion settings aren't' perfect.
