-Mitutoyo / Micromanipulator probe station with EZLAZE laser
-====== Condition ======
-The following issues have been noted:
-    * EZLAZE: PS missing
-    * XY stage: missing X motor and maybe some related brackets
-    * FS-60: possibly missing part…fine focusing knob?
-    * FS-60: focusing knob fell off (during shipping I think)
-    * Broken e-stop wire (from dissassembly?)
-    * Misc rusted screws.  Rust has not been found on anything critical

-    * water cooling is for chuck

-      * From move?
-    * CPC for thermal chuck (not motors)

-Open question: do I need the programming cable?
-    * I think I have one
-Initial current draw 50 mA.  Holding torque is not very good; slightly above off level.  Spikes to around 80 mA at startup
-BBB: mk-test.  Verified powers up
-changes 10 mA (min PS resolution) when try to move.  Time to play with settings cable
-Cable: MD-CC4 USB to RS422 Comm Converter
-Unfortunately:
-<code>
-The MDrive microstepping integrated motor and driver use the Serial
-Peripheral Interface (SPI) to configure the setup parameters.
-</code>
-Use bus pirate or beagle
-====== 2015-08-17 ======
-Decided to try one last time to see if I could move motors before messing with programming cables.
-Hooked up a test motor without any shaft load.  Spins fine and has reasonable torque.
-Hooked Y2 axis back up and was able to move it just fine.  Issues yesterday evidently were just due to shoddy wiring
-Conclusion: don't need programming cable.  Default settings seem to be good enough for now
-Also validates that motors are good enough.  Need to get 1-2 more for XY1.  Wait until I take it apart to verify clearances etc?
-X2 motor won't fit:
-    * original: 2.0"
-    * max: 2.2"
-    * mine: 2.7" (official IMS docs list Lmax: 2.65")
-Looked around and it looks like its going to be difficult to find any motors with integrated drivers at this constrained size.  Min length from vendors:
-    * IMS: 2.65"
-    * linengineering: 2.69"
-    * anaheimautomation: 2.98"
-Time to see if I can make these motors work.  I have some reasonably compact standalone IMS drivers (by coincidence also IMS) I can try to use

-====== 2015-08-20 ======
-Briefly poked at things.  Current plan:
-    * Try to use original motors.  This is combination of tight clearance in X2 combined with advantages of using existing wiring harness in X1/Y1
-    * See if I can get INT-481 to work with the slo-syn motors?
-      * A fourth INT-481 may cost $100
-    * This makes OEM650 more attractive since I have more of them
-      * They are slightly bigger but also easier to mount
-    * Z1 axis is a NEMA 34 motor.  Does not appear to be a slo-syn.  Maybe compumotor
-      * Low priority
-    * Make a schematic
-    * Fix e-stop loose wire (after schematic to better understand where it should go)
