The purpose of this project is to enrich both the participant and the Factor e Farm project. The scope of this specific project is to build the seeds for a MegaRap, which is a modification of the origional Torch Table designed to expand the range of build materials and capabilities. This is in the spirit of the RepRap project, but at a larger scale and lower precision. The initial goal is to design and build a torch table that can be added on to in the future but is still functional in its own right.
 
=Design Rationale=
 
*Rack for x motion - cheapest, most robust solution for precise motion
*Spring-loaded x and y motors

=Torch vs. Plasma Cutter=
*Comes down to initial cost versus long-term cost
*Plasma cutters - consumables cost $20 for 5 new electrodes and nozzle heads
**Electrodes are rated for 45 minutes to 60 minutes for 1/2" steel
**More expensive versions state they last 4 times longer - are heavier and have better temperature control
**For anything above 1 inch, torch is better
