Driver Board 6560 no free inputs!???/

[TheProCreator]

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.

nice!

I'll try that!

TheProCreator,

You may need to add a pull up resistor from +5 volts to pin 15 on the DB25
4.7K should be ok.

I am assuming you want to set the probe active low.

Here's the thread I'm following:

XYZ Probe modification

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?
