Parallel Port breakout boards, motherboards, and dedicated accessories / Re: touch plate

Thank you for your really complete answer. My pmdx 122 is configure to have j1 to j4 as input. The connector j5 is fully loaded with limit switches. I do not have any issue to use to use the same input for the touch probe and the touch plate. My main concern is to confirm if it is possible to connect com to the machine frame to get connection on the tool mounted on the machine

Hi,

I would like to add a fix touch plate to my CNC to do tool measuring operation. I would like to generate probe event with this touch plate. I already have a touch probe and I just want to add the touch plate. I would like to connect the touch plate on the PMDX-122 on J3. The PMDX is set to have COM at ground (J1 at 2-3). I would like to generate probe event by putting pin 2 of J3 at the ground. I would like to connect J3 pin 2 to the copper plate (touch plate) and connect J3 COM to the tool. My question is : is it correct to connect J3 COM to the machine frame to get connection to the tool?

Thank you
