The hand function looks great. It looks like you scaled up a decent amount (1.4 or 1.5 maybe?) which results in a little bit more side-to-side play in the snap-together parts. There is definitely some ringing and the fingertips do need some cleanup. I suspect speed is the issue. I see the rough fingers when cooling is inadequate, which speed can definitely contribute to. I've been able to fix the issue by reorienting the fingertips on the build plate so the slanted portion is directed right at the cooling fan. I've got no experience with Delta's so can't offer much advice there, but slowing down should help with the ringing. I know Delta's are known for high speeds, so perhaps dialing that down just a little can help, as you said.

Thanks for joining up with the group and let us know if you have any questions!

Thanks for the approval!

You are correct, I scaled to 1.7 for 2 reasons: 1) give me a better demo device using my own hand 2) test the largest size my print bed can handle. i know my bounds. 1.7 is as large as a gauntlet can get before i'll have to get a friend to print that piece (and likely the palm). :)

I'll definitely give your suggestions a go - i just finished a new effector and am re-tuning. it was stock and was the piece that was able to wiggle the most. I think this is going to help big time. I will also play with speed and temp. Also, great tip on finger orientation - brilliant - i'll give that a try too.

Looking forward to being an active member!
thanks again!
