 This page is about a reference DIY microscpoe control system similar to those used by John McMaster. Its intended to be a good starting place for what options might be for adding automated image capture to a microscope.

 If you know how many steps per mm, edit my_config/axis.ini to set SCALE. For example, if you have:
 * 1.8 degree / step motor
-* 16 pulse / step microstepping
+*1.8 degree / step motor
-* 2 rev / mm
+*16 pulse / step microstepping
 You will need to set SCALE to 360/1.8 * 16 * 2 = 6400. In any case, after you edit SCALE, launch the GUI and try moving against a known size object and see if it looks about right. You may want to also just other parameters like MAX_VELOCITY and MAX_ACCELERATION. Its easiest to copy repo to BBB using scp. Consider adding a script to the BBB named run.sh like:

 *b3i default configuration is to power I/O buffers from "SYS_5V", which means external power is required. The easiest way to do this is to supply 5V to the barrel jack using a second USB to barrel jack cable
