====== Laser Cutter Maintenance ======
Richard and I performed some preventative maintenance on the laser cutter:

  * Used windex to clean all the viewing ports
  * Vacuumed all debris out of the bed
  * Tightened up the head assembly belt and the set screws on the pulleys
  * Cleaned the ways with WD-40, then lubricated with oil
  * Oiled all bearings and bushings
  * Removed broken key from front cabinet lock
  * Cleaned mirrors and focal lens with optical wipes and alcohol
  * Aligned mirrors
