It's alive!

While the original motor still worked somewhat, it's bearings were totally shot and it was a single-phase motor, which allowed for no easy method of speed control. I decided to replace the original motor with a new industrial 3-phase motor and variable-frequency drive to get even, easy speed control and reliability. Here's video of the first test run. Since this was shot we've run a two-pass print run in which the new setup worked beautifully!
