Hi All,
I have just finished building my touchprobe, and now I need to hook it up to my computer. I have a 3-axis xylotex control board, and Im running mach 2 (computer to slow for mach 3).
My probe is wired NC (normally closed) this being said, in mach 2 under ports and pins, I need to set the digitizing to "active low" is this right?
My second question is, how do I hook the probe up to my xylotex board. I have an idea that it goes in one of the unused pp pins and the other end goes to gnd? I read in another post that resistors need to be installed to prevent the computer from being fried. Would anyone know what size this resistor needs to be?
Is there anything else I should be aware of before hooking up the probe?
thanks for your help,
Mike Grobowsky
