G-Code and Feed Rates question

Hey All,

I’m just getting started with my x-carve and v-carving. Currently using vcarve desktop and UGS.
My question is regarding adjusting feed rates in the middle of a run.

Basically, after all the big tough cuts have been made, and it’s working through taking much smaller cuts, or doing cleanup, is it possible to send a command and adjust the feed rate on the fly? I don’t know anything about actual g-code yet. If you can do this, what would the command look like? Is this just a plain bad idea?


It’s a frequent request, and apparently Grbl 1.1 will allow support for it.
