Sadly that didn't work. I powered off the 2 add on units, and rebooted the full node, it came up but didn't enable the miner, I tried to start the miner, it flipped to the dashboard but then went back to miner offline.
Can't seem to start that as a miner just on it's own...
At a bit of a loss right now, any help most appreciated

Is the node fully synced? If not then don't run the devices past Eco until you have a fully synced node. It has been reported that the miner may stop if it is pushed beyond ECO when syncing up with the blockchain.
If that doesn't do it then I would consider re-flashing the sd card with Futurebit's newest image and see if that sorts things out.
