Ganged axis does not work if defined in my_machine.h

[muhammadelmogy]

I want to enable Ganged Y axis but when I define this in my_machine.h it doe not work

#define Y_GANGED            1
#define Y_AUTO_SQUARE       1

In fact when I check the associated bins with the oscilloscope it seems like it is floating! But when I copy those definitions to the map file it would work! and of course when I build the project it gives me warnings about definition duplications !

I have my whole project in the attachments Mlabs-Controller.zip

At a guess, are you building with PlatformIO?

https://github.com/grblHAL/STM32F4xx/blob/2074a0efa842ced8a239888e47c9ddd4dd648f8c/platformio.ini#L19-L22

Yes you are right , but in that case what is the point of using my_machine.h Also, when I disable the override I get a lot of redefine warnings of the values in my_machine.h!

If building with PlatformIO, the idea would be to define the settings in the .ini file instead of editing my_machine.h

Makes it much easier to support multiple configurations for different boards without any code changes. Typically you would create a new [env:] section for your board with the required definitions in it.

Perhaps an additional platformio.ini file that do not override _mymachine.h should be added? Or the current one should be modified to allow that?

From memory, it's not consistent across the drivers (i.e. F1 & F4 override my_machine.h, but iMXRT does not).

Personally, I prefer the override if building with PlatformIO, keeps all the configuration in one place..

So in that case I need to add to the .ini file what ever I would like to have in my_machine.h file?

[muhammadelmogy]

If I override my_machine.h, how do I set ganged Y axis in platform.ini file? is there a parameters list to be used in the platform.ini file?

You would just add the extra definitions to your existing [env:mlabs_controller] section, they're the exact same symbols as in my_machine.h, but get passed into the build via the command line when building for that board..

  -D Y_GANGED=1
  -D Y_AUTO_SQUARE=1

Great, I prefer this way instead of modifying the source code. I will try it later and give a feedback after that if something goes wrong!
