Plugged it in, got a flashing led on motherboard, I assume this is correct. I successfully updated the firmware on both the motherboard and the extruder driver board. but ReplicatorG still says…
"Extruder board: Null version reported! Make sure the extruder is connected and the power is on"
I also read on the wiki that you should always turn off the extruder when done printing… (http://wiki.makerbot.com/plastruder-mk4) The extruder has a power switch? Confusing.
So two questions…
1) why the "Null version"
2) is there some way to turn off the extruder, or did they mean turn of the MakerBot when done printing.
