Hello,


I’ve recently been tasked with finding information to fix a Chinese Laser Engraving Machine. It has a Ruida RDC6442S-B (EC) Controller.

The exact Laser can be found at the following link (The Laser I’m working on wasn’t bought from this site though).

Essentially, the company that I do work for purchased this machine from a third party a few months ago. The only instructions we got from the Supplier was a USB with an arbitrary driver and a half chinese video showing how to install the software (which was quite unhelpful).


When they first got the machine, it worked perfectly. We use Lightburn. The machine has two unlabelled USB ports on the side. We first sent jobs to the Engraver by plugging in a USB drive into one of the ports. The Engraver would detect the drive and the job would commence.

However, the USB port on the machine broke off after a month. The side of the Engraver was opened and the USB drive was connected directly to the Ruida Controller via an extension cable and it worked.
However, we directly connected the Ruida Controller to the PC via the PC-USB port. With this, we could send jobs directly to the Engraver from Lightburn/RDWorks. This worked for 2 months.

Then, the Laser tube stopped working for some reason. A new laser was purchased and installed. The machine worked for 1 week.
Fast Forward to today, nothing is working. Connecting the Ruida Controller directly to the PC does nothing. Connecting drives to the U-Drive Port on the controller does nothing. I’ve connected a ethernet cable into the Ruida Ethernet Port, configured a static IP on the device for the network. The Ruida Controller comes up on the network, however Lightburn nor RDworks detect the laser at the IP. I want to reiterate the if you ping the IP or scan the network, the Ruida’s IP is detected.


I am at my wits end with this machine and need some assistance.


I’ve included the following links with pictures which should assist.
