Hi, We have been trying to use an Xpro V3 with a WorkBee CNC with our own custom modifications to utilise a handheld plasma cutter. However... Triggering the cutter causes a High Frequncy Pulse that radiates out and seems to knock out the USB connection to the Xpro. This was tried with a Raspberry Pi (Moderate success) and a laptop (Very fussy). After doing a lot of earthing the problem is still occuring. Anyway, I came up with the idea of using a TOSLINK cable to provide an alternative interfacing method, after some initial testing with a DIY FTDI and sending UART Data down the TOSLINK on a loopback I can Tx/Rx data, though after increasing the BaudRate to 115200 the data starts to corrupt. Frankly I think this is something I can work through by using the correct Capacitor values and Inverting the signal more efficiently. Anyway, my basic question is... can I reduce the Baudrate upon which the Xpro Firmware is expecting? 9600 is working well on my tests so far.
