Would be nice to add the ability to enable air assist when producing a material test grid. The only way I have found to do it is to manually force the pump on before generating the test grid, sending the M8 command to the machine before starting, and an M9 once done. A simple on/off button in the settings would be nice.

And along similar lines, is there a reason why air assist is not on by default anyway? It wouldn't hurt IMO if it's always enabled (and you have to disable it if needed) for most operations.
