Hi Had a look on YouTube, but couldn't find anything related to the above question so I've come here where I bought the Xpro from several years ago. All the kit was boxed up as my heart wasn't working as it was supposed to and couldn't get a lot of stuff done at that time. Anyway now all set up and ready to roll once the newly ordered shed arrives. Because the shed is about 25ft away from the computer (Its an HP desktop in my sitting room) and I don't fancy shifting it out to accompany the CNC router in the shed. I was hoping someone could explain about the 'Bluetooth Module' that fits onto the Xpro board. How it connects to the board and can you send the same commands from GRBL as you would with a 'Data' cable. I've got a cable that will just reach the CNC, but in a straight line from my back window. I'd have to detach it every time I finished of an evening and set it up again the following day. I read somewhere you can't have a Data cable longer than 15ft as it diminishes the signal if its longer. (It wasn't on this forum). I'd be grateful for any info concerning this module and how its set up to work as well, please. Thanks a lot.
