Hi everyone. I just finished my build I am using the set up I got from this site and connected to laptop. Every thing was working good just cutting just mirrored. Checked the form today and found a post to check axis direction so connected every thing and checked axis all good. I started up a cut and was going to do some more testing set the 660 where I wanted it and restarted repetier to set home to give it a shot. It started to cut then the laptop shut down so I shut every thing down thought the battery had went dead checked that all good 100% thought that was odd. Went back for another try connected every thing back up did not connect to laptop when I plugged it back in to the same usb didn’t think much about powered the cnc back up and nothing switched to another usb and the laptop shut down again this time I know battery is good thought not good. Since then I have tried my mouse and those two usb and nothing back to the one it was in and all good. So could some thing be wrong with the board or has some thing got crossed some where some how. Any help would greatly appreciated.
