CR-10 mini Z dual axis upgrade
thingiverse
This was entirely inspired by Myfordboy's Z axis idea, https://www.thingiverse.com/thing:2569379. Full explanation in the TXT file of what each part is and why. Links to all parts are in the TXT file. Basically the same principle but I changed the position of the second Z screw to place it behind the upright. This meant I needed a tensioning mechanism, so I used the 3 idlers you see in the photo. Sliding the end ones in tensions the belt, worked better than expected, all 3 parts the same so easy to print. All for a CR-10 Mini but just increase screw lengths for CR-10. I used a new 500mm screw (T8*8) but re-using the original I needed to add a bit to get full travel, see TXT file. May be worth buying 2 new screws to save messing about. My basic premise is that everything 'floats' so is infinitely adjustable. Includes a new Z motor holder to make adjustment easier. Top bearings are large and the bearing holders can move around so no precision drilling. One other reason I deviated from Myfordboy's version as I don't have his engineering facilities/skills. Only needed to drill a bit of aluminum angle, which also allows some 'floating'. Links to parts here (not as links in TXT file).
