Hi All, I hope somebody can help. I have a Aeon Pure Laser 1400x800 bed. A few days ago I was running the machine. The fume extractor (Big industrial thing) vibrated against the water chiller and knocked out the chillers mains lead, this led to the tube going pop with water everywhere. New tube purchased and fitted. However when I turn the machine on the head goes to the home position and that s it. Even though the controller is lit you cannot do anything with the controller, but using lightburn on the laptop you can toggle arounf the bed.and send the head to origin position. I am unable to use any of the functions of the control panel so cannot reset the Ruida 6442S. On the Ruida itself, lights 3 & 9 are permanently on. Light 15 is perm on and light 14 flashes which I think is normal. Can anybody help.
LED’s 3 and 9 is the home switch Y (LmtY-) and 9 is water protect.
I don’t follow how you lost a tube, but if water went everywhere it’s likely it damaged something else.
Replacing a tube doesn’t have any effect on the controller as they are separated by the lps. Not knowing where all the water went may be your issue.
Since it homes properly, I’d say you’ve lost the controller or it wouldn’t home. What I mean is that all the electronics need to work for it to home. If it homes and then you have no control over the Ruida, first suspect is the controller itself.
Could the water have gotten to the controller?
Betcha it doesn’t, because the LmtY- LED should not be on after it’s homed.
If the machine display shows both X and Y as 0.0 after homing, then it’s good to go. If the Y axis shows 3000 (or something huge), then I suspect that switch has some flood damage.
Now, if it’s properly homed and the LmtY= indicator remains on regardless of where the gantry moves, that’s another issue.
Just going by what he’s told me. Can’t read their mind.
I think when mines at the X- 0 point, I get a illuminated X axes indicator. Never tried the Y???
Next time I fire it up, I’ll have to check these.
Shouldn’t be lit, because the backoff after homing deactivates the switch: fast seek / backoff / slow seek / backoff.
Well, that’s on this machine. We’ve already established yours is different. 
thanks for the reply. the led 3 light no longer stays on, sits just led 9. The tube blew at the firing end so not near the ruida. When i switch on the machine it automatically homes. The controller screen says x axis 0.0, y axis 0.0 but z axis 3000. The screen then goes blank but still lit.
That’s good: X & Y both homed properly, Z axis does not home automatically.
That seems like the screen has a heart attack after homing: the controller can still accept commands from LightBurn, but the display / keypad (known as a “Human-Machine Interface” = HMI) is defunct.
I’d start by unplugging & replugging both ends of the HMI cable (between the display and the controller), even though the initial startup looks good.
Beyond that, perhaps electrical transients during the tube failure killed either the HMI or the controller. Sounds like handwaving to me, too, but there’s not much debugging to do other than replace possibly failed parts.
