-Sherline 2000 CNC info
-====== Spindle CNC ======
--11-26 project
-Problem: I got this system 8 or so years ago to learn machining and build robots.  At the time I was learning plenty with manual milling and didn't really step up to do real CNC machining until much later.  That's when I realized:
-  * Didn't come with spindle CNC instructions (encoder, driving)
-  * This is not a Sherline option
-    * Although the encoder does look like the [[http://www.sherline.com/8100pg.htm|Sherline one]]
-  * The company that did it went out of bussiness
-I could try poking around CNCZone and such (probably still should) its probably simple enough that some reasonably quick tinkering will get it working.  I tried guessing settings in the Axis GUI before without success.
-===== Overview =====
-Standard Sherline driver box has a mini-DIN connector on the side labeled "Spindle".  This goes to the spindle controller that has a matching plug as well as an RJ-11 for a tachometer.  The spindle controller also has a switch for "manual" or "CNC".  When flipped to CNC the spindle stops.
-===== Internals =====
-The driver box has a 26 pin header (J6) that is presumably for accessories.  An IDC cable runs to an IDC to mini-DIN converter board is mounted to the top of the driver box.  It has a few capacitors (PWM smoothing?) but is otherwise blank.  There are unused pads for some ICs and other components.  I suspect the mini-DIN is essentially directly connected to the DB-25.
