To All Who Might Know::

I have one of the Hobby CNC Micro Stepping boards; revision #1, copywrite 2006. The problem is that I cannot set the amperage ratings for “Z” and “X”. I have measured the reference 5 volts on the board; it is 5 volts. The input supply voltage is 19. The maximum reference voltage on “X” is 2.7. The maximum reference voltage on “Z” is 2.7. “Y” maximum is 4. 7.
Obviously there is a problem with the “X” and “Z” adjustment in order to set the proper amperage ratings. PLEASE HELP.
BTW:: Does anyone know how to contract these people directly? Please advise.

Cordially,
Richard A. Sales
