I'm using a RPi 3 with the latest stable build. When I try to print to my Replicator 2, I get the following results:

[15:43 15.07.2016] This printing job failed due to errors above.
Please try printing agan (depending on the error please power cycle the printer, 3DPrinterOS software and check that USB cable is <1.5m length and has screening and filters), if still does not work please contact 3DPrinterOS support team.
I'm currently hooked directly to the RPi 3 from my Rep 2 with a USB cable that is about 0.5m in length.
Any thoughts on what's going on and how to fix? I have six MakerBot Replicator 2's that I would very much like to use with 3DPrinterOS.
