Help with Ruida 8445 controller
Posted: Wed Jan 21, 2026
I bought a laser and it was reset to factory original with Chinese as the only language selection. For many reasons I decided to just replace the Topwisdom TLA1 with a Ruida 8445 which I found a deal on.
I have it running and burning, but a couple problems remain and not all features are working. Rather than making a laundry list here I am hoping to solve them one at a time.
My first problem is on startup, X, Y, and Z values are all 99999. I've done what I could find, checking X&Y limit switch function, and setting machine homing to the correct upper right corner to no avail. I can reset the values to zero after startup and the machine functions, but I can't get the startup to act normally. any ideas or help is appreciated.
I will tag these questions China-Ruida because there are more to come. Thanks
