Yay! I sorted it out.
I went back to an older config file I had saved and just started changing blocks of code one at a time until i figured out what was messing up.
I guess I hadn't paid attention after getting the bed probe set up. I had the bed probe on pins shared by the heater. Its all working, for now.
I edited my config file to change tool offsets since I've changed extruders. After resetting Heater 1 no longer shows up. I tried reverting to a saved config file and it didn't help.
