This thing lets you use thinner z rod with your current m8 carriage ends.
This is a test part that I printed but didn't end up testing. The theory is that a thinner z rod would be less likely to cause wobbles in the print if it was non-straight. This piece is the id of a 10-20 coupling nut (yes, I'm american... I know... It's what they have in stores here, so It's what I designed for...) and the od of an 8mm nut. You should be able to
1- print this,
2- press in a 10-20 coupling nut whilst still hot
3- swap out your flexible coupling for something that will grab the smaller 10-24 rod
4- use the same x-carriage and print with fewer wobbles!
For this to work you will need:
~26in of 10-20 rod.
4 10-20 coupling nuts. (these are longer than usual. Mine are 3/4" long)
your existing x axis, untouched.
your spring (if you use one) from between your m8 nuts.
something to couple your threaded rod to your motor shaft.
There is an openscad and an stl, feel free to make a metric version if you live in the 21st century.
NOTE: I designed this piece thinking that my z wobble was caused by my 8mm rods being bent. The real fix ended up being that my rods were constrained at the top and bottom. I used flexible tubing as a top coupler and got rid of the bottom bearing. I would recommend that fix first to anyone who is following down my same path. If that fails, try this part out and report back!
