Cura 3.4.1 will not show "build plate temperature"

[donsenior 0]

I installed Cura 3.4.1 and I am unable to go into the settings under materials and click on the option "build plate temperature".  The pop up note says it is hidden and I will need to go into G code to tell Cura my printer has a heated build plate.  I have already told Cura that I have an Anycubic i3 Mega, what else do I need to do?

It doesn't think you have a heated bed.  Try going into machine settings and I think you can tell it there that you *do* have a heated bed.
