Hi all,
I'm a completely newby with Linuxcnc but was able to get the basics working.
But sorry for the maybe beginners question.
I use a Mesa 7i76e and my xyz steppers are working perfect.

I created a simple macro file which is also working fine when I execute it with the mouse click in MDI mode.

I connected a physical switch on input-00 which is also working as I can see in "auto mode" (the "Load a new program" h-button.button-0 is executed when I press the external button)

But in MDI mode, the first macro is not getting triggered.

My custom_postgui.hal is:

net macro-switch1 gmoccapy.h-button.button-0 <= hm2_7i76e.0.7i76.0.0.input-00

After searching all docus I understand that a macro can only triggerd by external button by going through the virtuell h-buttons. Is this correct?

Any idea what I can try to get macros triggered by a physical button?

Many thanks & best Regards,
Joerg

I don't know any other method to run a macro by a hardware pin other than via the h-button.button-0.
What is the problem doing it via this pin?

Maybe you can add a VCP and express that what you want to do in a little python script.
What does your macro do?

Thanks Hans,
when I run Linuxcnc from the terminal, the output shows me that the "Button macro_0 has been clicked".
But the macro_0 is not running and nothing happening.
When I click the same macro_0 with the mouse, the macro_0 is executed and runs his gcode.

The macro_0 is a very simple gcode as attached.

I'm running Linuxcnc version 2.8.1 and gmoccapy 3.0.9.1. (not sure if it's worth downgrading ..)

On the end of the day, I try to get a machine working like a "Rose Engine" for engravings ;-)

You are running a fairly old version of Gmoccapy. 3.1.3.8 is the version in current 2.8.3 release. Maybe it's worth upgrading ;-).

However, your file needs and M2 command at the end. Then it works for me also with gmoccapy.h-button.button-0. (only tried with 3.1.3.10)

It is working now perfectly after upgrading Lcnc to 2.8.3 with Gmoccapy 3.1.3.8! 

I insert the M2 command before, but it was not solving the issue.

Thanks so much Hans! highly appreciate you help!
