I'm using the Console app with my Printrbot Metal Simple. The gcode console echoes back the command I'm sending, but I don't see any output. Specifically, I'd like to run the M501 command to find out what my settings are.
If I run the G29 command, it does the Z-axis calibration. So I can tell that the commands are being received by the printer. The issue is just that the console doesn't show any of the gcode responses.
