Machine: Garden variety K40
Board: old = M2Nano, New = C3D Laserboard (G code)
Firmware: As configured from C3D
Problem/ Question: My issue is almost identical to Is my C3D LaserBoard a DOA? but everything functions normally.
If I plug in a energized PSU as supplied with the Laserboard there is a quick shower of sparks but unlike the reference post, the machine is functioning properly. I have not read any voltages but the lights are behaving as expected and the machine is running well.
From the “if it ain’t broke’ don’t fix it department”, should I be concerned? I typically leave the C3D board plugged in at the board and just energize the PSU at the AC plug.
Thanks to all in advance.
