Has anyone had success printing the Zortrax ball bearing model at 50% scale, .19mm layer height? About half way through the print one of the balls will come loose and get hit by the print head. Everything falls apart after that. I think machine vibration, particularly during the tight circular paths, is causing the failure. I was able to print it with a .29mm layer. Not sure if that was a fluke or if the larger layers give a stronger bond between the balls and the raft. I have the machine on a very rigid base and the platform is level. Any ideas?
I had the same result when I first got mine. I never tried again though. I did print a very nice gear bearing though.Has anyone had success printing the Zortrax ball bearing model at 50% scale, .19mm layer height?

Dhatw.
More support angle to have more contact surface with the ball?

The balls will still come loose with the 80 degree support setting.

I've printed several of the bearings at full scale with no problem, but the one I tried at 50% failed the same as yours. I just assumed the reduction in scale caused the contact area between support and ball to get too small to fix the ball.

Ok, Thanks for trying. Hopefully they'll figure out a way to minimize vibration on rapid direction changes in a future update.
