Basics

An Open Source Mid-High Budget CNC Router
As per their website "A Low cost, High-Performance Steel Frame, Ball Screw & Linear Rail CNC"
It seems to be a well built machine, and despite cost seems quite accessible (the use of Rectangular Steel Tubing instead of Aluminum Extrusions / Cast or Milled Pieces etc is especially smart)
3D Printed Drill Guides are also heavily used taking the possibility for measurement error / the frustration associated with all that out of the picture
