Ruida644XS - Lightburn

Hello everybody,

I lasered normally today, now suddenly Lightburn or RDworks can no longer connect to the laser ?!

After reading what I could find here, I have already plugged in the LAN / USB cable directly below, but also no connection.

Reset, restart etc. also do not help.

The display without power supply is dark, with a USB cable connecting to controller appears, it appears as if the connection is being established.

Where can the spontaneous error still lie?

Does somebody still have an idea?


This is not normal. When you power your machine on, the display should light up. If it lights up only when you connect USB, it’s because the USB is supplying power to the panel.

Check your power connections to the controller.
