[mrorange26]

I have just added a heated bed to my delta printer and I don't know how to enable it.On my lcd I only see the hotend temp.is there a way with gcode commands to turn it on.

M190 S60
will set the bed temp to 60 celcius and wait for the bed to reach that temperature.

M140 S55
will set the bed temp to 55 and return immediately (it won't wait).
