New GCodePrintr beta V2.10 introduces powerful macro keywords.
Macro keywords allow you to build macros with user input and more control.
It also comes with a predefined “Filament change macro” to make it very easy to change the filament even during print.

This is brilliant Mathias, this is what the 3d printing world needs! I’ve been using LCD interface for about a year now and gcodeprintr has taken a back seat but I may hook my tablet up just for this new feature - excellent work
