Tool height setter and 3d probe inputs

More
17 Mar 2024 19:07 #296149 by natholego11
Hi,
ive got a 3 axis probe (NC) and a tool height setter(NO), im trying to put them into the same pin so I can use the same motion.probe-input.
I was following this example, but I keep getting an error that my tool_probe.in0 (and I assume in.1) are not defined

forum.linuxcnc.org/10-advanced-configura...nsor?start=10#233776

here is my current HAL. what am I missing here?

ok, got that working, new problem, when I unplug my touch probe the pin for it (since its NC) goes low. so when I probe with my tool height setter linux thinks the probe signal is high. is there a way to distinguish between which pin to use for what action in the controller? or do I have to leave my probe plugged in all the time?

just to close the loop on this. I ended up using a NAND 7400 chipset and flipped the signal going into the 7i96 board. seems to work pretty well.

In my config, I have a gcode-controlled "pin" that chooses which of the two probes are active, and the routines that do toolsetting switch probes during those.  I tried a dumb "or"ing of the probes but the toolsetter was too sensitive to vibration when the machine was running full out, so I had to disable it somehow anyway.
