Hi
I am newbie to the CNC world - I would like to start working on my DIY CNC router, I would like to get the same design and characteristics as the FireBall Meteor.
I am trying to make a list of the main components (mainly the drive system) to build the CNC , can you please help me understand what key components I am missing? also how to adjust this project fit my low budget?
I posted before and someone suggested the g540 board, so here is the current list I made:

I will probably need Some Aluminum Extrusion (still working on the SketchUp), connectors, bearings, bolts etc (I am fine with any of the items here until I finish the sketchup)
