How to send g-code to printer using Host

I am trying to calibrate my X and Y axes, and need to send the M503 command to the printer to see what the current values are. 

But when I use the Manual Control section of the GUI to send "M503" I get a "Unknown Command: Nxxxx M503".  So what is the correct incantation to send a command to the printer.  It's not obvious from the documentation.

  • You are doing it correct. The unknown command message comes from the printer so the printer does nut support that command I'd say. Send e.g. M114 and you would see position in response.
