Yes, if power goes out it may fall, sometimes the steppers appear to be shorted when off though so they turn only with effort, must be something about the smoothie clone board. I rarely have power outages, I usually just put a piece of foam or bubble wrap under the bed, in case it were to fall.

You could change the main gear on the stepper to say a 36 tooth and probably avoid that.

Steppers are supposed to be hard to turn when energized. Put small pulley on stepper and large pulley on driven shaft.

What happens if the power goes out? Does the bed come crashing down? Looks great!

Yes it does come crashing!
I am thinking of where to put a spring to solve this

It's very interesting, I had some problems with z wobble and basically fix it using bronze bushings instead of linear ball bearings. Could you make a video explaining your mod and the printer working?
