Webbing to use in a pulldown wench. break point 1250 lbs for a 1 inch wide webbing. We can spring load an arm then use a small winch with this webbing to pull the arm into position. Fast and easy. Accurate with an encoder on the winch.
Motor Controller from vexpro. This is the CAN interface controller with the ability to attach an encoder, POT, and/or limit switches directly to the motor controller. This controller would give us the ability to do direct PID control of a robot mechanism. Should simplify the software and should be very fast. It would also make the wiring much cleaner and easier to trouble shoot.

I like this system but during build season will need to be able to get ready for ordering quickly. Not sure we have funds to pre purchase any quantity of this based on the current funds available. Looks like a minimum of 5 days shipping unless we pay more.
Reference guide to using the CAN interface Jaguar motor controller to connect an encoder of pot to get speed or position control, PID, directly to the motor. This could greatly simplify PID controlled devices on the robot.
These guys have a pretty impressive review list of 3D printers. The makerbot was on their list but did not make the top. Have you checked into any of these others. Many I have never heard of before.
