Basic macro questions

Hello Community,

I have some basic questions on macro usage in linuxcnc.

Is it possible to execute gcode within self defined macros (e.g. M101)? All examples I found searching the web are executing hal_cmd or other bash code. But no example showing how to let's say move the cnc mill in a rectangle shape.

I found out, that I could do such using python and import linuxcnc module and execute a mdi command. But that does only work as a single G-code line in MDI mode and not when I use that M-code within a ngc file.

Can you give me a hint how to use macros properly?
Or maybe macros aren't the best way to do that?

Ubuntu 10 LTS version
with axis 2.5

Or just use gmoccapy, it support macros.

For details see the corresponding WIKI page.

Make a file called rect.ngc which contains something like

Then call it in your code with

o<rect> call

Thank you all for your help.

The subroutine solution (ngc o-code) worked for me.
... for now

Now I will dig a little bit deeper in python based subroutines (found some python code that looked like subs).

Hallo John,

you are right, but you can run a complete subroutine in gmoccapy or touchy by just pressing one button.
I thought, that is what he weant's.

And I have to to also some advertising for my GUI
