I have a Monoprice Maker Select v2, and the default for the bed temp is 30 C. I always have to reprogram it to 50 C every print after the print start, and AFAIK there is no way of programming the default to 50 C.

I use CURA and I don't see a bed temperature setting in the file settings or profile.

Is there a way to set the bed temp within the GCODE, and if so, what is the line I need to put into the GCODE file?
