More Screw Mechanism Testing

 Now controlled over CAN and USB, using a gui based on the espresso machine software

The the USB communication plus Python GUI gives me nice live-plots and logs.  Here's a plot of the fast position steps:


  1. Huh. PSU showed up to 4.8xA for “unloaded" movement. What kind of power do you think you'll need, instantaneous and/or continuous?

  2. I wouldn't call it "unloaded", most of the energy goes into the rotor at the beginning of the stroke.

    The transmission ratio was optimized around a ~1kw motor output power constraint. The duty cycle will be very low though.

  3. Yooooooo. This is starting to look very interesting!
