The 4 Axis CNC Machining Center

Intro
I picked up this Intelitek Expert Mill VMC-0600 with 4 axes, automatic tool changer, pneumatically actuated collet chuck, mister, touch probing, tool probing, mix and max limit switches on x, y, and z axes… and it runs a Beaglebones based Acorn board and CNC12 control software.
I have experience with 3 axis gantry lasers, 3D printers, Vinyl Cutters, Inkjet & Laser printers, etc… but i’m 3 days into machining, so cut me some slack LOL. Also please point out anything I messed up, missed, or could improve on. I appreciate all feedback. I’ll update this post as I move along.
