#1 · September 22, 2021, 4:41 am

Hello. I just built myself a laser with k40 PSU, tube and Mini Gerbil. Contraction is wooden with 2040 extrusions. I am tfying to engrave some pictures on tiles. It works once before. And then it starts to disconnecting. I prepare picture and push start. 1 second after, it disconnects. Problem solved with moved jumper from psu to usb powering. But its disconnecting randomly. In the middle, on start of engraving.
When i move axis' it works. But with laser on, it drops

I have checked power saving of usb, power control, new driver, new cable (3m). Can you help me? Thank you
