Linuxcnc 2.8, Mesa 7i76e and Rotary Switches

Hello -

I am setting up a new 7i76e to replace my 10-year old 5i20 setup and need some assistance

I used PNCCONF to generate the configuration and assigned input pins for Axis Select and Jog Increments because I wanted to use a simple 4 position rotary switch to select the axis and jog increments, I don't want to use an MPG to do this because I already have a USB Jog pendant (XHC-HB04) and don't need any additional MPGs.

When I send a signal to the pin in question either using GND or FIELD VOLTAGE the pin does not change value TRUE/FALSE. I am hoping its a simple case of not knowing how to wire a rotary switch correctly to the pin in question.

I am using AXIS for display but I am not opposed to switching to some other GUI to get this to work.

Any thoughts ? Thanks.

P.S. I have been using Linuxcnc since before 2008 - since pre-HAL EMC2 era, this just happens to be my first post to the forum. And now that I have finally joined the forum, I will post more details on my SX3 conversion. In the meantime you can see some content at the esarworks YouTube channel. esarworks CNC Conversion

Hi -

Its a 7i76e, and I am watching the Signal from Hal meter so I don't think the pin numbering is significant.

Here is an example screenshot from a Virtual Machine, since I am not near the real system.
