About this model

This is my massive CNC capable of cutting a full 4x8 sheet of plywood with room to spare! This is optimized specifically for cutting plywood, and I believe this is probably the least expensive way to build a CNC capable of accurately cutting plywood in a reasonable amount of time. There are other designs out there, but I've yet to see another one that maintains performance and accuracy while keeping the overall price below $1000 for a 4x8' cutting area. I really enjoyed designing and building this, and I hope it can help lower the barrier of entry for makers looking to build the kind of things you see on OpenDesk or WikiHouse.
