CNC Flame cutting preheat time and pierce time on screen

[bdrotaru]

Is there any way to read values of preheat time and pierce time for flame cutting from UCCNC screen?
To avoid somehow editing program in Sheetcam just to change time!
Thanks

What I did was to add fields on screen to enter both pierce height and pierce delay.

Then the post processor that I wrote calls those values and adds them to the gcode.

However I do not use sheetcam so can not describe how to achieve that with that program.

Can you please share screen, post and a cutting gcode?? I would like to have a starting point.

This is my modified screenset showing the relevant fields that I use.

So to achieve touch off (plasma not oxy) the code includes macro calls that read the pierce height and delay.

Again I do not use sheetcam so I don't know how much of this can be done within sheetcam.

Then the post processor that I wrote calls those values and adds them to the gcode.

This line was incorrect.
The post processor puts the appropriate macro call in the gcode.
Then that macro calls the values.
