Overview
The CNC Torch Table is a table capable of cutting designs out of metal with a 2-axis torch controlled by computer.
The CNC Torch Table provides a quicker solution for cutting sheet metal, especially into intricate patterns that are difficult to cut by hand.

Prototype I Currently being used in experimental production runs. Tighter integration of Digital Fabrication is being researched as is the software toolchain (which is a current bottleneck).
Prototype II
- First step: perfection of mechanical design for replicability to 1/32" over 4x8' area
- Need open source controller, end stops, and z height automation/detection.
- We could use existing structure, with modifications. Right now we use gear rack. We can simplify the carriage structure.
- If we want to go all out - we could use full gas flow control - but that is probably beyond the scope of the present program - as it would require expensive parts until we can manufacture them ourselves.
- Open source stepper motors would be a good addition - if we could find somebody to design/fab them - that would be great.
- Computer vision for fully automated cutting would be the last step.
- Next steps: stiffening frame design to accommodate router heads
- Interview with owner of Ben's excellent DIY table setup in Smithville, TX:
Suggested steps from Luke Iseman
video of ben's setup:http://opensourceecology.org/wiki/CNC_Torch_Table photos of OSE's current table, including measurements: http://opensourceecology.org/wiki/Torch_Table_Build DIY standalone sensor ideas: http://opensourceecology.org/wiki/Sensing_Distance_from_Work_Piece . note particularly the circuit i found for an independent z-axis control CNC circuit mills: http://opensourceecology.org/wiki/CNC_Circuit_Mill . comparison of existing kits, and updated parts list on mantis 9 ( http://opensourceecology.org/wiki/Mantis_9 )
recommended next steps: 1. get the candcnc.com 's dragon-cut 620-4 and implement on the current table. utilize your same bearing setup for the z-axis. 2. build the mantis 9 , but use the snaplock electronics.
