Hi. Does anyone know how to use the "Gantry Blueprint" and the "Track gantry set blueprint"/"Track gantry set blueprint 2". I've tried and still hasn't worked. I've searched for tutorials but can't find any. I've read the Dev Docs (i have attached a file below, on page 5) but it wasn't helpful. It doesn't describe what to put where. Is there anyone who knows how to use this ? Thanks in advance
