Re: Turns out Helical Beam Couplers aren't meant to handle that much stress . . .
I know you can't see it in the video but your coupler got into a resonant mode where the parts were vibrating independent of the lead screw. When the resonance hit the right part of the coupler, the stresses increase significantly. That is why you had parts of the coupler deform more than other parts.
