I have an Lead 1010 with V3 Sparks controller and have been using it for quite some time with no problems. I just purchased a 4.2 Jtech laser and set it up to use on my 1010. Now I can't connect via USP to my Lead or Jtech. Below is a screen shot of my controller. Any help would be greatly appreciated. Thanks.
Disconnect the new wiring you added and try again, probably while wiring the laser you made a short or miswiring mistake somewhere preventing the board from booting.
Possible you miswired something and damaged the board? 1) If it was all working up to then, the question "what happened" points to adding wiring 2) As it was all working up to then, the PC, software, drivers etc are unlikely to be the issue 3) check Device manager > Ports while plugging and unplugging the device for clues 4) take it one step further, disconnect everything except USB and test then 5) Try a different PC just in case
