Well, I was getting tired of having to load my prints onto an SD card by formatting, loading the file, and inserting into the MakerBot because when a print fails, I have to repeat the process. So, I finally decided to swap the FTDI USB to Serial cable for hardware serial cable. Now, I can print from the computer directly without worrying about slowdowns. It's faster because instead of relying on a driver to convert the data and push it over the USB where it is then converted into serial, it just uses the hardware serial controller, which uses a whole lot less processing power than USB does.

Here's a video showing my MakerBot workstation:

I also have it on YouTube, but YouTube makes my videos all jittery when it transcodes them. I only really use YouTube when I need to use the annotations.
