Damn, i would’ve never thought about that. Went to check the speed in prusa, would you look at that…

Perfectly corresponds to the bulges.

Thank you, Detective Carighan!

It took some time to find the culprit.

It’s under:

Filament settings -> Cooling -> Cooling thresholds -> Slow down if layer print time is below: # - and - Min print speed: #

I am running a bit hot, yes, 215, and the extruder is bowden feed. It does tend to ooze a bit like all bowdens do, that’s why i have to get my speeds and accelerations on point, because the “dynamic” speed/extrusion settings never provide good results for this printer and i don’t know how to account for the oozing on speed changes.

I’d love to upgrade to a direct extruder, i’m currently using e3d v6 hot end. Do you have any suggestions?

According to JerryRigEverything, they actually run you through a mac mini on their server farm. He said he has info about that confirmed by the devs. Not sure what’s true, but i usually trust him, seems like a good guy.
