Simple command line tool to send gcode to serial 3D printer/CNC machine. Much thanks to the original author for this very useful tool. We can now support multiple machines from a single server. Unlike a certainly feature-ful popular multi-limbed package which openly refuses to support multiple machines per instance. ("Buy another Pi, they're cheap!" Grrr! That's not the point!)
quiet mode - very minimal output
verbose - much like it is now
debug - show everything, including comments, responses and the grimy undercarriage
bar graph progress - 0-100% bar graph, like wget-ish?
RESET action - send codes to printer to turn off heaters and park head. In case of unexpected stop of sending
maybe:
identify device on port? (If possible, M115 helps)
enable temperature display during printing (it's suppressed by default right now)
background mode? nohup style, start a print and go do something else
