    Good evening
    My robo 3d r1+ bed is not heating up, I have replaced the green connectors, they were fine but I thought I would eliminate that issue just in-case. Using my multi-meter on resistance I am getting 2.1 ohms, which I think is in the good range (I have compared it to my other robo 3d) Also the bed light in R23 is not coming on like it does on my other printer
    Any suggestions of what I should try?

    Sounds like a possible bad MOSFET on your R1+ mainboard. Since Robo doesn't have spare parts (or doesn't really care about servicing a discontinued printer) take a look at a thread by @Geof where he shows how to replace the R1+ board for a generic and cheap standard RAMPS Arduino combo. Nothing about the R1+ mainboard is special, it is just a RAMPS/Arduino clone that happens to be a single board.

    Actually the R1+ still has a two-board "stack" but they used a slightly custom RAMPS clone that is now unavailable.
    There is a thread to do the swap to a standard RAMPS board (<20$ on Amazon) and it is not hard. If you want to go that route let us know.
