      I’m picking up some steppers for Morgan and figured I’d use a double shaft for the Z motor. I plan on putting a printed knob on the shaft opposite the lead screw coupling for a sort of “manual override” of the Z axis without having to reach under the machine to turn the lead screw by hand to raise/lower the build plate. Seems like it could come in handy.

      Figured I’d throw this idea out there…

      With my drill bit lead screw I can move the bed by hand if the motors are not engaged.

      As it would be with the threadless-ball-screw-solution we’ve discussed already.

      In that case go or it! I am also quite used to just pushing the bed where I need it when the motors are turned off, and I would miss it if gone…

      Seems good. Just be careful that the arms do not collide with the knob.

      With my drill bit lead screw I can move the bed by hand if the motors are not engaged.

      I have the threadless deal on my machine and moving the table by hand won’t turn it. It’ll bind like any other thread. I have to reach under the machine and turn the screw to raise/lower the bed.

      Not a big deal but one of the things I like about the rostock is the easy ability to move the effector around by hand making fiddling easier when the machine is powered off. Just something I’m used to.

      Fiddling is a way of life with reprap \o/

      I can see how the drill bit lead wouldn’t bind which is actually pretty cool!
