Mesa 7i96s to Gecko G540 with simple 3 axis Router

Hello Folks Newbe here.

I mistakenly though I could easily convert my Shark SD120 to a Linuxcnc setup using a Mesa 7i96s to a Gecko g540. After hours of fooling with it and being misled by AI I now realize there is no easy way to setup the HAL and INI configs. I purchased the hardware and would like to make it work so any help would be greatly appreciated.

Thanks,
Doug
 

How is the Mesa wired to G540?

If the G540 is connected to the 7I96S parallel expansion connector, you should use
7i96s_g540d.bin firmware, that configures the 7I96S's P2 expansion connector the G540
pinout, Then basic setup can be done with pncconf. No need for AI, that just a time sink here.

Thanks for the help, making much progress. New question:
What is the syntax to negate these inputs?

# external input signals

# --- MIN-X ---
net min-x     <=  [HMOT](CARD0).gpio.000.in

# --- MIN-Y ---
net min-y     <=  [HMOT](CARD0).gpio.001.in

# --- MIN-Z ---
net min-z     <=  [HMOT](CARD0).gpio.002.in

# ---setup home / limit switch signals---

net x-home-sw     =>  joint.0.home-sw-in
net min-x     =>  joint.0.neg-lim-sw-in
net x-pos-limit     =>  joint.0.pos-lim-sw-in
 

Thanks for the help. Sending this because I'm not sure I posted my next question in the right way..

[HMOT](CARD0).gpio.000.in-not

I tried that and get the following error:

Pin 'hm2_7i96s.0.gpio.000.in-not' does not exist

Works okay without the -not

weird but this works
{HMOT](CARD0).inm.00.input-00-not

Thanks

For GPIO it's in_not

INM is a better choice for inputs though  because it has built-in
debouncing if needed.
