When I connect it to the breakout board, the Probe XYZ and Probe Z button in the GUI are always lit up green and the standard touch plate no longer works.
Since this is a normally close tool setter, I have set the following config:
IO → I/O Configuration → Switches
→ probe: normally-closed
The TLS is connected to pin 15 (red) and 7 (GND).
This seems to make the TLS work but the touch plate not longer works.
The question are:
Is there a way to make the touch plate work on the Normally-closed" setting?
Would getting a normally-open TLS work in the same config?
I think the issue here is that the controller only has one logical probe interface, so configuring it to be normally closed renders the normally open touch plate undetectable once the tool setter is installed. The easiest solution is converting the tool setter from normally closed to normally open with a transistor/NOT gate.
Checking my BB controller configuration document I find that pin 22 on the I/O is labelled “Probe”. My controller is set to “Normally Open” on that pin, which is also labelled “Probe”. If you’re not using both of your devices together, connect the new probe’s positive to pin 22 and leave the negative connected to ground, then change the pin 22 active state in the configuration to “Normally Closed”. That might be the easiest solution to your problem.
Well, it depends…If you need to use both of them before running one job, it would be sort of awkward. You could wire a switch that would connect one or the other, then change the settings in the configuration when you switched; that might work. I think that the simplest option would be to buy a normally-open setter; then you could wire it and the probe (also NO) in parallel, and either one would work. You could build a simple inverter circuit as described above, but I’d be very averse to doing so, as a small error might damage the controller.
