Title: Touch plate and Probotix PBX-RF board?
Post by: jeffmorris on July 16, 2012, 07:38:42 AM

My CNC router has Probotix PBX-RF board. Pins 10, 11, and 12 are for home switches. Pin 15 is for E-Stop switch. Is pin 13 free for touch plate?

10,11,12,13 and 15 are inputs to the parallel port so pin 13 should work fine for you.

I searched this forum for messages related to touch plates and found out that I have to write code that lowers the Z-Axis until the router bit touches the plate, raises the Z-Axis, tells me to remove the touch plate, and press a key to lower the Z-Axis to the workpiece. How can I write the code?

If you do a search for possibly tool setting  or toolset you should find code on the forum.

I tried to wire the touch plate to the PBX-RF board but when I plugged a stereo phone plug into a mono phone jack, the "Digitize" light in the "Diagnostics" window stays on. Do I need a mono phone plug or can I cut the tip off the stereo phone plug? In the "Input Signals" dialog box, I set the "Probe" to enabled, port 1, pin 13, and active low. I set the X, Y, and Z Home Switches to enabled, port 1, pins 10,11, and 12, and active high.

I got the touch plate working after using different phono plugs and jacks. I have USB numeric pad usually used for notebook computers. How do I assign a key stroke command to VB code to start the code running? I'm using the VB code from http://www.machsupport.com/forum/index.php/topic,10088.0.html

You  set up a hotkey for the VB button in one of the screen designers.

Is there a list of unused numeric pad keys? I tried a few screen designers and they confused me because of lack of good documentation.

Dont think there is such a thing as a list, personally I have all hotkeys disabled in screensets. I think MachScreen  may list all presently used but afraid where I dont know as I dont use it.
