 Specifications:
   * Power output: 40 W (theoretically, anyway)
-  * Cutting area: Clamp area is 8"x4".
+  * Cutting area: Clamp area is a little less than 8"x4". 7" x 3.5 should easily fit inside
   * Coolant: currently a mix of distilled water and RV antifreeze (3:1 ratio), a few drops of algicide, and a few drops of dish soap.
   * Exhaust: Fume extraction via a BOFA AD-Access fume extractor/filter

   * Jumpered water break detection since detector is seemingly NFG.
     * Test again with new coolant pump to make sure it wasn't just low flow?
+    * Tested again. Maybe backwards? Maybe NFG.

   * How to format your SVG drawings for K40 Whisperer: https://www.youtube.com/watch?reload=9&v=9wYvbenigtk
   * Basic concept- using K40W, move the head over the upper left hand part of your work. maybe use the "laser test" button to make sure you're actually over the work. and then choose whichever of your engrave/cut options (do engraves first, and cut last).

 Power levels:
   * Wood (engraving) - 8% does a fine job on the random wood pieces we've tested with.
-  * Acrylic - 25% was great for engraving, but slightly insufficient for cutting (the cut edges did snap off easily, though)
+  * wood (cutting) - 11% was sufficient to cut 3mm baltic birch plywood?
+  * Acrylic - 25% was great for engraving, but slightly insufficient for cutting (the cut edges did snap off easily, though). 33-35% should be good for cutting at 10mm/s.
