• Get two Makelangelos. They come with everything you need.
• Assemble and mount each one in opposite corners of the room.

pen plotter:

• Print a plotter. It is printed upside down to avoid overhangs.
• put m3 screws through the side holes to tighten onto the pen.
• make a loop in the end of the threads.
• put a thread through an arm at the top of the pen holder and hook the loop over the screw near the bottom.
• Insert a pen and tighten the screws. You shouldn't need a death grip. If the pen can slip out the top of the holder, that makes it easy to recap/replace.

top/bottom (camera plotter):

• Put a 1/4-20 bolt through the center of the half with the grooves.
• Attach the 4 strings from the steppers to the bolt so that the grooves face down.
• Put the second half onto the bottom of the bolt.
• Add a 1/4-20 nut to keep the whole thing together.
• Add a camera to the bottom of the bolt.

Software instructions coming soon.
