Goals
- Torch table using standard flat bar and angle iron for structural support. borrowing electronics from D3D CNC Torch Table.
- Possibly use multiple ball bearing rollers with spring support to tolerate debris on bar surface
- 3D printed mounting points that minimize drilling/welding
BOM
- 1/4" x 6" x 9' Flat Bar - discount steel
- 1-1/2" x 1-1/2" x 1/8" x 9' Angle - discount steel
- R6 Ball Bearing - grainger
- Stepper motor NEMA 17 - reprap page
- Stepper Driver

Design
CAD
- Sketchup basic idea - github
Notes
- Mcmaster doesnt seem to carry GT belts? but the have other sizes.
- GT seems to be popular size with 3D printers for some reason
- Perhaps a wider belt should be investigated for higher torque
