See below for anyone who wants to take a look at the full assembly of @MrBeaver Z-Axis with some personal mods.
CAUTION - If you do decide to download and import this to Fusion 360, make sure to create a new folder and import into that. I make extensive use of sub-assemblies and parts folders. The Fusion 360 import brings these all into a single folder so it’s a bit of a mess. Also, if you want to delete you have to do it in the right order respecting dependencies. It’s a dose to do.
Other things to note
This is based extensively on Luke’s design but there are enough small deviations that the parts are unlikely to be interchangeable.
I’ve only copied over the work on the base plate needed to make the Z-Axis, I haven’t included Luke’s additional design work to allow this to be used for any other axis.
Unlike Luke’s original design, this is vapourware. I’m waiting for my ball screw before starting so this only exists as a design. Subsequent issues could arise when I go to build it.
This won’t work with the ball screw Luke gave dimensions for above, The required ball screw is included as one of the models.
Any feedback welcome. Happy to answer any questions on the Fusion 360 drawings.
