Machine Features: 
Same as last time except now it's on a 15 tick clock and can handle negative slopes, backwards lines, etc. (all 8 octants). Also, I made a better system for handling the octant determination that involves a single 1 bit multiplexor, not 2 4-bit multiplexors. The build is about 2/3 the total volume including air (with control room and display in the exact same place) and is significantly improved in terms of timing circuitry.
How To Use: 
Same as last time ;)
