Machine: _it will be a full spectrum laser_
Board: Cohesion3d LaserBoard v1.0
Firmware: _ "I have a new board and I’m using whatever it came with!_
Problem/ Question: _After getting my new board everything seemed to be working great on my bench with only the power supply and usb plugged in., and it appeared to be getting a signal from light burn (I had a port and lights blinked on the board ).
Then I realized I needed different connectors for my external stepper drivers in the FullSpectrum laser.
After getting the cables from cohesion 3d I tried again on my bench with one cable plugged in so I could probe voltages, I got the sparks coming from the power supply connector which sounds like a known issue, then all of a sudden everything went black and after cycling the power all I get is a single red led in the led stack, and I no longer get a USB connection. The board never left my bench.
Also, the strip of bare copper on the backside is pretty hot to the touch.
Any ideas on how to fix it? I can do some rework if that’s the fastest way to get it fixed.
Thanks for any help and advice
