    Robo R1 Plus. Extruder heats up, build plate does not. First time having this issue. Printed PLA for a year now.
    Help?

    You will need to do some testing.

    The RAMPS board (top one on the electronics when you look from bottom of printer) has an output to drive the heated bed.
    You need to see if it has voltage going to the heated bed when you are commanding the bed to heat. Put a meter (set to read 12v DC) across the terminal marked Heat Bed Power in this pic. See that you have 12v.

    This will only be the case if you have the printer turned on and your software set to heat the bed (or you can do all of this with an LCD controller if you have one and do not need the PC attached in that case)

    The bed was heating to 50 degrees with no problem. When I attempted to increase bed temp to 60...it stopped responding. Could this have anything to do with it?

    Not likely. Even when Robo had the limit on the bed heaters (some R1 models) the limit was 85c.
