Made a Lego brick Christmas ornament on 770mx

Milled a Lego brick Christmas ornament on my 770mx. I started from Customizable LEGO compatible Text Bricks by Lyl3 - Thingiverse

Here’s the Fusion 360 with the CAM (and notes) that I used:

Here are pictures of the brick up close: (note: I engraved too deep on the “K”):


Turned out pretty neat. Always learn something doing a project.

If you attempt, be sure to change the first setup’s stock size. I used a piece that I had, so it is a non-standard size.

Re-did the ornament. Changed a few things. The engraving is still a bit too deep, but it looks ok.

The neat thing is that they stack ok.

Steps:

  1. Rough cut the stock (update the Fusion for the stock size)
  2. Probe (and set Z to top of stock)
  3. Run first setup
  4. Flip stock
  5. Probe (and set Z to top of parallel)
  6. Run setup2a.
  7. Re-probe (keeping Z to top of parallel)
  8. Run Setup2b
  9. Flip stock
  10. Probe and set Z to top of stock (although it might make sense to make it +0.05")
  11. Run Setup 3

There are notes on some of the steps in the Fusion file. You will need to have a tall 1/4" end mill (as noted in Fusion)
