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

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
    • https://reprap.org/wiki/Choosing_Belts_and_Pulleys
• Perhaps a wider belt should be investigated for higher torque
