Display Clues for Cutting Block

I'm trying to run CNC plasma using linuxcnc and axis interface. While cutting a drawing we have multiple parts to be cut, and often times we don't need some parts not to be cut. Every section that will be cut starts with M03 and ends with M05. Can I not just display a section number for each section inside M03 and M05 on the drawing display area of the axis GUI. Actually, this is something I have seen in Chinese plasma CNC controllers, they call it pierce number, and when entered by the operator plasma directly cut that section. Those controllers also offer flexibility to cut from the current position or machines reference position, though this stuff can be done in linuxcnc with help of G-codes. Anyone's help will be greatly appreciated.

Thank You,

P.S.: In the image attached you can see cut number given at the start of each section, starting from number 1 and ending at number 4

You can do something similar with subroutines. This would cut O1, O2 and O5 bus skip O4 and O3


You can use descriptive names too, using <> as string delimiters

Thank you Andy for your response, but this will be in the G-code editor section I need to view the section number where the G-code is rendered.

I don't think you can do that with the current code. The G-code preview only displays G-code, not arbitrary graphics.

Not a issue. I figured another way out.

Thank you,
Andy.

If you don't mind asking me here in this same forum, out of context to the heading question, can you help me with external offsets.

External offsets are contained in an experimental branch so need to be compiled from source code
github.com/LinuxCNC/linuxcnc/tree/dgarr/external_offsets
It contains a large number of sims and examples for various applications demonstrating different applications.
