When looking at G-code RepRapWiki [
reprap.org] I see that these commands have partial support in dc42's fork. However when I try to execute them I get invalid code message. There is also no mention of these codes in source code. I have installed out of filament sensors on extruder's endstops but cannot see any other way of using them to pause print when filament runs out. Any idea what is going on?
Reality is in fact virtual.
