Homebrew PCBs

"Have to be careful with this though, four coils on instead of two, so you 
have to make sure your motors are designed to run that way as well.  More
than a 
few will overheat if you use full power in all four coils.  Definite
improvement 
for the ones that can run this way though."  - Alan


Nah, gonna go with the herd  :D  and stick with unipolar steppers for this
first machine.  I'll probably move up to bipolar for the CNC version.  Right
now with the 'discovery' of the UCN5804, things seem to be a breeze to get
going, economical to start up and difficult to screw up.

This drilling station is to help me save time when I fabricate PCBs.  It was
not meant to be a project to take my attention for several weeks.  Yeah
right, famous last words...
