-"k2scope"
-I've acquired 2 or 3 K2 IND systems and have mixed/matched parts to combine them into a working system.
-Basically what happened was I tried really hard to get one at local auction but kept getting outbid.  I found one at reasonable price on eBay (after some negotiation) and acquired it.  However, it didn't come with any objectives.  Somehow after this I managed to win a very nice system at industrial auction for pretty low price (lower than the objectives would have cost on eBay).  I ultimately had to mix/match parts from the two systems to get good optical quality.
-Nikon clamps are 8-32 (revolving nosepiece and such)
-====== Historical notes ======

-====== BOM ======
-Given the quality of this system and how much I bid to get other systems, this system has been surprisingly low cost to build.
-Combining parts into a working high quality system composed of:

-===== Motor details =====
-Motor: Harmonic Drive "HiT Drive SERVO ACTUATOR, RH-11-6001-E100DO5"
-    * Encoder (sold with motor): ENCODER-02A 1000P /R
-[[http://www.harmonicdrive.net/products/actuators/rh/|Website]] decoding of RH-11-6001-E100DO5:
-    * RH  Type: RH mini series
-    * 11  size 11
-    * 60  Output shaft rated rotational speed (r/min)  60 r/min
-    * 01  Rated output (W) x10  10 W
-    * E  incremental encoder
-    * 100  encoder resolution  1000p/r
-    * D  Encoder power supply 5-12
-      * Case says 5V
-    * O: open collector
-      * aha!
-    * 5: ?
-      * Not a special suffix
-      * indicates 5V operation?

-Glass rotary encoder with open drain outputs.
-I opened this up because I was having trouble getting signal (2014-09-29) and thought it might have been broken.  Now I know it was just an open drain vs actively driven issue.

-Above: troubleshooting encoder signals
-When I asked Gecko about my linear encoders they didn't seem that familiar with them (which seems a bit odd but w/e).  In any case, they recommended the follow qudrature encoders:
-    * CUI AMT102-V
-    * US Digital quadrature encoder

-====== Driver box ======
-Had a driver box but it got lost in the move.
-Trying to troubleshoot why not moving.  Notes from a while back
-<code>
-mA drive required
-"TTL level"
-ohm resistor + diode
-(3.3 V - 0.7V) / 100 = 0.026
-</code>
-Currently using 5V.  Is that somehow too much?
-Driver boxes are on: motors are locked in place.  Any chance the shutdown input got triggered?
-Double checked pinout vs above and it sounds like its wired correctly with step/direction
-Maybe try switching them if its backwards somehow?
-Can't find the k2 stepper config.  How many steps per mm?
-M-Drive manual has note:
-<code>
-TTL Inputs: 3.5 to 6.0 V pulse height
-ns pulse width minimum
-mA minimum current
-MHz maximum pulse rate
-</code>
