It says that: " If you combine this with a motor and a microcontroller, then you can build a closed-loop positioning system whose speed and position can be precisely determined and controlled, even if something unexpected happens."

Questions:
1. I need a Micro-controller board in between the Magnetic Linear Encoder, in this case Arduino Uno, and the makerbot controller board for translation, is this correct?

2. I have a cupcake the very 1st version, has anyone close the loop to this machine? How do you install the magnetic strip to the XY axes?

thanks,
