House Printer

Intro

Read the Inspiration below. Next step is to start in FreeCAD and we can add to it.

They show the gantry. That is a basic space frame structure.

If we use hydraulic motors with encoders and chain instead of the belt, we can do this readily using a Universal Axis style system. Perfect applications.

Steel is a dollar per pound, and hydraulic motors that we would want to use are $300 each. This would make about $10k in steel, and $1800 in motors. Solenoid valves would be $200 each, need 12 total. We can use the same controller as the 3D printer for the brain.
