Review on 🌩️ Cloudray Ruida RDC6445G CNC Laser Controller for Laser Engraver and Cutter Machine - RDC DSP 6445G by Morgan Gilmore

I've only used the 6445G for a month, it shows a fatal error, I've used all branded devices, tubes, coolers, power supplies, etc. I have used mechanical limit switches it worked for a month then lights up when Y+ is always activated on the main board and when Y+ is activated it also always activates Y- so the Y axis can't move and I checked the ground connection to each Y-, Y+, X-X+ and Y-left without answering. waste of money. I'm not new to this, tried to fix it with the help of many pros, but it's a technical error, this motherboard should have better safety strings.
