I’m looking to slowly put together a custom build, and am currently laying out the mechanical components. I was wondering if the community has any preferences when it comes to securing guide rods and linear bearings, and why. The ones that come to mind are:

  1. Threaded End Internal/External Tap (It would be cool if they made bearings with an external thread)
  2. Simple Press Fit
  3. Perpendicular Pinning or Set Screws
  4. Retaining Ring Grooves
  5. Capping Flange

Press fit and a zip tie works for me on lm10uu. I also like the look of those with a flange though I have not tried them.

i dont prefer zipties, but they are ok, never had prblem with them.

I’m trying something new. I posted a simple diagram a few weeks ago if you care to check it out. The guide rods are in the core-xy style though.

I own a DaVinci 1.0, and know it uses internally threaded guide rods (which is probably a great way to go), and some odd clip like bearing holding surfaces (but I can’t stand their linear bearings or clip style).

My issue with pre-threaded rods I have found on the internet is that many are expensive and don’t generally have a finish (I was reading and watching videos that suggested a chrome coat helps considerably). I know it isn’t a requirement, but it sounds like it helps quite a bit.

Of course one may be able to simply tap the end of regular guide rods.
