What’s more fun than one Stanford Bunny? A few litters!
These at 50 mm/s feed came out a bit jittery. The ear overhangs were particularly messy:
Another litter at 20 mms/s had better ear overhangs and much smoother coats with less overall jitter:
The obvious shear line across their tummies came from my messing around with the HBP cabling, jerking the X stage while preventing the cables from snagging on the Y stage. Moral of the story: don’t mess around with anything inside the box while it’s printing!
They have little droopy tails:
I think 25 or 30 mm/s would be better all around, as it’d move the extruder away from the Z stage’s mechanical resonance at 1.10 rpm.

Ed, what are the warts?
As nearly as I can tell, it’s a Reversal problem: there’s a small lump of plastic left at the end of each thread, even with enough Reversal action to completely prevent drooling while moving to the start of the next thread.
I tried cranking up Clip a bit, but that left gaps with zits.
I’ve been gently fiddling with Reversal settings and not seeing much progress, so it’s time for some concerted experimentation.
[…] the process of tracking down the source of those Reversal zits, I noticed the motor mount flexed slightly as it reversed. That could produce a bit of backlash, so […]
