The loss of a hard drive, and source code prompted a reprogramming of the CNC microcontroller.
Features:
     
     1.   24 bit words.
     2.   48 bit multiply subroutine.
     3.   48 bit divide subroutine
     4.   Subroutine calls from interrupt
     5.   A 20 iteration Cordic resolver that supplies both sine and cosine. (Does not include Quadrant resolver, add two more bits of definition to your circle!)
     6.   Real time serial communications @38400.
     7.   3 Axis Cube root motion.
     8.   4000 pulses per inch. That's 4194.30375 inches @ 0.000250 resolution.
     9.   So far the program is up to $D01 leaving 766 bytes left. The program has plenty of room for compression.
     10. Gecko Drives with Automation Direct Stepper Motors are the primary movers this time.
SOON! Testing is almost complete. Source code to follow
