This is my take on a precision test for the [Shaper Origin handheld CNC](https://www.shapertools.com/) that fits many items on a 6"x6"x1/2" piece of wood or MDF, with ideas from "Cut Test Samples" by Philip1 on ShaperHub. This shape was made by my personal SVG making library at https://github.com/ChrisLomont/SimpleShapes, a C# library for making 2D shapes with simple code in C#. This shape is now one of the demo files there.

I used 1/2" thick MDF. It would work nicely with various hardwoods too.
Shaper Origin
Router bits are the default 1/8", 1/4", and engraving.
1. Tape down wood with 2 sided tape, since you will be cutting out shapes. 2. Place the image, ensure everything fits and the Origin can move over all of it. 3. Install the 1/8" bit, make sure to tighten the collet and the screw for the router, and do the z-test, and set the cutting size on the Shaper to 1/8" 4. Set to cut 1/4" deep with 0.01 offset (we will make two passes on cuts at 0.01 and 0.00 offsets to get nicer edges) . 5. Cut the three 1/8" bit paths: 2 marked "Inside" in the image and 1 marked "Outside". 6. Do the four corner holes at this setting 7. Do the two pocket sets marked "Depth" for depths 1/2" and 1/4". (You may be unable to do the thin slots with the offset at the moment.) 8. Set the offset to 0.00, and repeat steps 5-7. 9. Set depth to 1/2", offset 0.01, and do only two of the holes marked "Inside" and "1/8" and do the 4 corner holes. Do the one depth that is that deep. 10. Repeat step 9 on offset 0.01. 11. Changing the depth for each Depth marked pocket, do them all with each at the correct depth. Use the 0.01 and 0.00 offset method. 12. Switch to the engraving bit, ensure everything tightened down, do the z-test, and set the Origin to the engraver bit. 13. For each text piece, you must select it, change to On-line cuts (Not Inside or Outside). I hope to fix this later. 14. Do the 8 sets of engraving depth items (just the numbers such as 0.010"). Be sure to change depths for each one. 15. Pick the depth you think looks best. I chose 0.015". Set your value. 16. Cut rest of the text with that value. Cut the diagram if you want it. 17. Switch to the 1/4" bit. Tighten, do z-depth, set Origin. 18. Set to 1/4" depth, 0.01 offset. 19. Cut the 3 holes for the 1/4" bit line. Trim around the outside of the 6x6" shape to prepare freeing it. 20. Set offset to 0.00, repeat step 19. 21. Set the depth to 1/2", offset 0.01. Cut TWO of the 1/4" holes marked as "Inside". 22. Cut around the outside, leaving a little bit near opposite corners to hold the piece stable while you finish it. 23. Set offset to 0.00, and repeat steps 21-22. 24. Finalize the part by carefully cutting the two last bits holding the piece to the surrounding board. 25. Gently sand to smooth edges. Be careful not to remove from the edges so you can measure them carefully. 26. (Optional) Measure things with a micrometer, write results on front or back, date it, so you can check Shaper precision later if you need to compare. Note: during cutting, one of the little pegs popped off and blocked the Shaper airflow, and I didn't notice. Sawdust backed up in the cuts and caught on fire. Be careful and watch your cuts!
