Difference between revisions of "Nema23 integrated Prusa Z with Vertex and rod clamp (Q53232)"

Nema23 Z axis for regular Prusa Mendel. 2 required Integrated Vertex and rod Clamp I have some surplus/salvage Nema23 steppers that are a little too underpowered for CNC but should work fine for Prusa. I can replace 2 Nema17 steppers on my Prusa freeing them up for extruder and x-carriage on a new one. The motor should not be bolted down hard as this would cause more problems if the toolhead impacts the print(or the bed!) and allows for a little wiggle just like Prusa's original design. I used the vertex profile, so measuring and tightening the frame remains the same. Edit your frame-vertex.scad file so it doesn't produce a shape by default. I include the one I use, so edited, it's from the Prusa Felt Branch. Notice that the motor does cross the top of the z-smooth-rod. Position the smooth rod so that it doesn't quite touch the motor. This was a compromise so that spacing between the motor shaft and the smooth rod is "Standard" -- the same as with a nema 17 design. Still working on a printed coupler. But any Nema23 to 8mm coupler should work.
