Block Delete enabled or disable during program was created by Diederik
l'd like to enable or disable the block delete while running a program. I connected Halui.program.block-delete-on to a button to try and achieve it, but no success. Whatever state it is in by the time I start the program, that it stays in. I write my program in a way so that I can clear long shavings if necessary, then I stop the spindle in the program. Sometimes it is not necessary, then I prefer to continue with the program. And not stop the spindle. On fanuc system, I'd normally do like this :
/m5
/m00
/m3
This allows me to stop spindle when required, and I can enable and disable block-delete while program runs.
Kind regards
Diekie

IIRC the halui block delete request is active only when program is paused, so you also need a run/resume and prog pause halui buttons.
That said, it would be far more useful to also have spindle control and coolant halui buttons, you can then pause the program, stop coolant and spindle at any time during a program.

Thank you for your input. I did try to pause program, and then to enable/disable /Block delete function, but doesn't seem to work. Any other advice?

There is no work around - it is a short coming of linuxcnc.
adding a bug report or feature request will help to get it changed.

There is already a bug report for this. A note on the maillist may bring the subject up again.

To achieve the same thing you could write a G-code sub that tests an external pin and stops the spindle, retracts, etc only if the pin is set.
So, perhaps your main G-code could include
And then a subroutine in a file called "clear.ngc"
