    Can I substitute a B+ for the B version?

    I see no reason why not. I wouldn't swap the 3 for a 4 unless you are rebuilding the OS image for the Pi/OctoPrint from the ground up.

    I hope so, I have one coming in mid December.

    I bought it as an additional spare after replacing everything in the system. I thought I was constantly trashing the SD card. Turns out that if you rename the printer in Printer Profiles it will not boot past the initial Robo screen. It does not happen until your reboot after changing the Name. Damn, it took awhile to figure it out.

    The Raspberry Pi 3 B+ does NOT work.

    Works OK on my C2, but ... that proves nothing really :)

    I got a new 3B+ in a sealed box. Tried it on 2 R2's and it would not even go to the Robo boot screen. I suppose it could have been a bad unit. I bought at Amazon for $75 so back it goes. The two authorized distributors have the 3B for $41, but do not have stock. My guess is that chips are not available for manufacturers and those with stock can get high prices. Eventually the price should come back down.
