Added timeout to output buffers destined for USB Fixed bugs in thermocouple code Reallocated thermocouple pin numbers Made Roland mill and inkjet support conditional and normally disabled Fixed issue with thermocouple code messing up the timekeeping system, which was suspected of causing the network to be unreliable Added support for M577 (thanks chrishamm)
