I just went through that myself. I redid the flash drive, either let the node sync or shut the node off, then power it down, start both standards, then power on the full node miner, and make sure the node is either fully synced or shut down. You should be able to punch in the IP of it to get to the UI start up or shut down the node, and start the miner, with all three showing up. My issue was either it would mine, or the other two would mine, not all three at once, reflashed, did the methodology stated and they all work again.
