[mention:1fea68f71fde47f2beff1fc2c7890056:e9ed411860ed4f2ba0265705b8793d05] Nice job! I like the pencil CAD. I am working out the plans for my CNC with an 18" sq bed. The bed stays still and the gantry travels front to back, and up and down. The tool head(s) move side to side. I plan on having multiple heads; Router, 3d print head, and laser engraver. Since the bed never moves calibration is easier. about 2 years ago I when to the Large Adivtive Show (here in Fort Worth) where I saw an air-operated tool changer. This is one example, another would be the pull stud which most CNC tooling uses. but it's not really what I want. Think of this you have a plate (male) with two dowels pins and two more bolts another plate with the same geometry, with holes (female or receiver) with the tool mounted to it. Now If the bolts are replaced with an air-operated retention mechanism, tool changes will be a simple thing unplug the tool head, turn off the air and just pull the tool off. Side on the new tool turns on the air and reconnect the cables.

and this is one way without the air

Nicely done with great documentation. I use Fusion 360 too but really enjoyed your hand drawn illustrations.
