Test all CNC primitives CAD → CAM → CNC

[VillageHubertChen]

Tasks

• [x] HC, ML: Write to do list
• [x] ML: Do one primitive completely, then let HC review
• [x] HC: Write change list based on review
• [x] ML: Redo first one, let HC double check
• [x] ML: Redo all others. Trigger HC it is done in comment.
• [ ] HC: Move all this into one Article

  Procedure

  1. CAD
  2. Draw Primitive in SolidWorks
  3. Export to DXF and STL
  4. CAM
  5. Import to CAMBAM to Reference Layer
  6. Redraw in CAMBAM. Split into 4 layers: Drilling, Cut Out, Pockets, Tabs
     • snap back to grid
  7. Generate G-Code
     • manually check G-Code: a) No nonsense b) coordinates in Grid?
  8. Verification
  9. Import G-Code
  10. Simulate
  11. STL Compare
      1. Import STL file
      2. Run Compare
      3. Check if any red or yellow

         List of Primitives

  12. Drilling
      • 11 Drill Hole
      • 12 Drill Pattern (Not tested now)
  13. Cut Outline
      • 21 Cut Rectangle with sharp corners
      • 22 Cut Outline Rectangle Rounded Corners
  14. Cut Pocket Rounded Corners 31 Standard Pocket 32 Fast Pocket (Not tested now)
  15. Holding Tab (Not tested now

      Writing Procedure

  16. Write down all steps in a comment below
  17. Make Snap Shots.
      • Put into folder. Give Snapshot a good name. Refer to it in Article. Leader nn numbers in file
      • make rough cut of snapshot, save as png. use skitch, give file name as per below:
      • examples
      • 01-draw-primitive-sw.png
      • 02-export-dxf-settings.png
      • 03.export-stl-settings.png
      • optimize display width and layout to best use 853 px wide (give or take)
      • optimize height as little as possible

        What to save per Tested Primitive

        Items

  18. Snap Drawing SW
  19. Snap Import CamBam
  20. Snap Drawing CamBam
  21. g-code file
  22. Snapshot compare in CutViewer

      Managing Files

• File Name: Index No + Item No + PrimitiveName + ItemName
• Example: 11-1-DrillHole-DrawingSW.png

Verification Procedure

1. Draw Primitive in SolidWorks.
2. Export to DXF
3. Export to STL
4. Import the DXF to CamBam and rename the layer to Reference
5. Add new layer for Drawing and redraw the primitive to snap back to grid
6. Generate G-Code and manually check G-Code
7. Import G-Code to CutViewer
8. Simulate G-Code in CutViewer
9. Run STL compare

@VillageHubertChen When testing "22 Cut Outline Rectangle Rounded Corners" and "31 Standard Pocket". I have the same error message "Invalid floating point operation" when running STL compare

@VillageHubertChen The four Primitive tests is done
