Assembly instructions & Laser Template
Updatd to use the GM3 gearbox instead of the GM4 - March 24, 2011
First of all, be aware this file is 24" x 18". It's the template we use for lasering out the Useless machines, so
the documentation is also on this size format. Print at your own risk!
The heart of this design is the clever use of a "double-pole, double-throw" and limit switch. These two switches
route to the motor in a way that ... well, make it want to turn itself off!
