This weekend I finished hooking up my MakerBot Cupcake CNC to use Bluetooth. This has been done before. However, I've not found any instructions for setting up ReplicatorG (aka RepG) to use a Bluetooth serial connection under Ubuntu. I'm using a BlueSMiRF from SparkFun and hooking it up to a Gen3 RepRap motherboard. This is slightly more complicated to use than using a Bluetooth Mate because the pin-out does not match the TTL serial header on the RepRap motherboard. Paeae Technologies has a nice tutorial for using a BlueSMiRF . There's also a nice tutorial for using a Bluetooth Mate on the MakerBot wiki. If you use a BlueSMiRF like me, I recommend using short pieces of wire to attach the BlueSMiRF to the female header. It's easier to do than bending the pins like Paeae Technologies suggests. Also, you can see that I have the RTS-O pin disconnected. Although I didn't experience any problems, the Paeae Technologies tutorial reports that leaving it connected c
