Help develop MP3DP v5!?!

:hushed:

That is a pencil diameter hardened steel shaft, breaking that is insane.

THAT feels like an understatement :rofl:

Its also worth noting that we run the pullies all the way down on the shaft. If I remember right we use a piece of paper as a spacer for setting them. Unlike some situations where the pully is out towards the end of the shaft and has a lot more side load on the motor.

Yes, Yes it is. Funny thing is I did not think it was under that much tension at the time.

I feel like that contributed heavily to the situation I had. Was on the Y axis drive on a machine built out of 3/4 MDO board. Ended up designing a jack shaft for lack of a better definition.

I wonder if that motor had a defect/crack in the shaft? That seems way more plausible than over tightening the belt and breaking it.
