Mesa 7i96 and LinuxCNC 2.8 PnCConf

Why oh why is linuxcnc so picky?

Because if it was not picky/precise about pin names you could not trust its behavior.

Its easy to get pin/parameter/signal names right, just use the available tools to list the actual pin/parameter names.

For example to list all pins/parameters and functions, you can runs this command:

halcmd show all

to show just 7I96 pins/parameters you could type

halcmd show all | grep 7i96

You can also re-direct the output of these commands to a "donor" file to copypast from, so you never need to actually type pin/parameter names:

halcmd show pin | grep 7i96 > 7i96pins.txt

Or halcmd show all *7i86* (halcmd accepts wildcards)

Unfortunately that does not always work, not sure why

Pulled up halshow, put pins 34-39 on "watch" and actuated the limit; no indication of anything happening. I can run 24v into TB3 1-11 to switch low right? Just asking because there doesn't seem to be much of a reason for the limits to not work.

hm2_7i96.0.gpio.034.in_not is the proper way to wire the pin to switch low in mesa, yes?

7I96 inputs are on GPIO 0..10

Got it. I'm getting the "limit on error" again and it resolves after removing the "_not" and halshow still isn't showing the limits trip.

Just to confirm, my x-min-home is "hm2_7i96.0.gpio.000.in"
