Control Gcode program loaded into Axis

Hi!

I'm wondering is there any way to control Gcode that is loaded from ngc file.

We want to create some small "CAM buttons" for simple procedures like rectangle pocketing, array drilling, bed cutting, and etc directly from EMC2 without any external CAM.

So what do we need:
1. A way to create Buttons which will start external script. (it can be done with PyVCP or Glade VCP)
2. A way to post Gcode to running AXIS. Here's where we've stopped.

So is it possible to change gcode in the AXIS?

PS sorry for my English

Thanks a lot! I'll take a look!

Hi Nick

Just a hint
Don't go pyvcp and M1xx commands, and or phyton. You will not be happy.

That's nice, but we wanted to make more complicated gui.

For example, we want to have buttons with images describing their behavior instead of using usual text buttons.
Or place text entries on the image to reach mutual understanding.

Is it able to do it using ngcgui?

Do you know is there any way to change Gcode in Axis using python / gladevcp, or not?
And about mdi commands, can they be multi line or not?

Here something to test:

If you comment the o<p103> sub and the o<p103> endsub lines
you can start them as M1xx via pyvcp

If you put ( all including ) in a file p103.ngc you can start as phyton.

Via phyton you will get what you expect, including preview.
Started via M1xx and pyvcp button you will see nothing on axis and program starts direct execution ( I dislike that )

That's why you have recommended to avoid it.
I do not like it too .
