I have this board and I am trying to hook up a Blue screen z finder probe in mach 3. According to the info I have, pin 15 is supposed to be free. Problem is, there is no screw terminal for it. How am I supposed to access other pin in/outputs if there are no terminals???  |

Get a little creative, Flip the board over and solder the wire directly to pad 15 of the DB25. Jeff...

| Here's the thread I'm following: http://www.cnczone.com/forums/mach_w...ification.html Nothing is mentioned about adding 5v for the probe lead, however he does set it at "Active Low" Let me see if I can get this to work. I will need to know how to solder up a resistor to the pin 15 lead if this doesn't work. Can you walk me through that? |
