after working really well for the last couple of projects, the locking tab on my router did finally cam out and popped the notch while being under load from the bungee cord:
Went right into the most expensive piece of acacia I’d ever strapped to my Maslow …
I had planned to redesign the z-axis quite a while ago, based on The Meticulous Z-Axis, even bought the parts but for some reason I never really felt like starting the build… now the machine kinda forced me into it. Not my preferred way of motivating myself but hey, what can you do…
However, this will be the build log for all of those who may be interested.
I was able to get my hands on a couple of fancy-dancy parts for cheap; now I’d like to see how they are going to perform.
The main difference will be the linear rail - instead of having plain rods ‘flapping in the breeze’, I’ll use some sturdy 16mm supported rail with TBR16UU bearing blocks.
A 16mm ball screw plus SFU1605 ball screw nut will help to minimize backlash, so it’ll be goodbye bungee cord!
Everything will mount to 20x20mm aluminum extrusions I had left from an earlier project. They happen to be exactly the size I need for the linear rails!
I’ll keep the original motor - with a higher pitch than the thread on the router it’ll be a bit faster without having to change anything else (apart form the value in the SW, obviously).
