Thing-O-Matic: Multiple Bunnies vs Print Speed

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:

Small bunnies - ragged edges - 50-100
Small bunnies - ragged edges - 50-100

Another litter at 20 mms/s had better ear overhangs and much smoother coats with less overall jitter:

Small bunnies - ragged ears - 20-100
Small bunnies - ragged ears - 20-100

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:

Small bunnies - droopy tails - 20-100
Small bunnies - droopy tails - 20-100

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.

    1. 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.
