Tom,

I'm not sure what it's really there for, but I find it handy as I litter my code with prompts, to tell me what to do (put in a new piece of stock, re-zero, Z, etc.). This makes running a program for the first time in a while fairly idiot-proof. But, when I'm making many copies of the same part, as I often do, the prompts are really only necessary the first time or two through. After that, I like to be able to turn most of them off. Block Delete makes it easy to do this.

If you can come up with a way to enable/disable that could be controlled either by the app or by the G-code itself, it would make my day.

Regards,
Ray L.

There should be a flag that can be set to enable/disable (I would love it if this could be done through an M code or a parameter so it could be changed on-the-fly in the G-code....). There is code already in there that detects the slash, and sets a different return code which appears *should* make it ignore that line, but instead seems to cause an abort. Search rs274ngc.cpp for "RS274NGC_EXECUTE_FINISH".
