Hello everyone. I stupidly and accidentally plugged my 50w blue and Gray laser into an outlet with reversed polarity and burned something up after about 60 seconds after turning it on.
I have replaced the switch power supply and the ruida controller/lcd screen but still not fixed.
Observations:
LED on new power supply still doesn’t light
LED on laser power supply doesn’t light
Ruida LCD doesn’t turn on or BEEP
Air pump works with switch
Water pump worked after initial issue but no longer works with switch (not necessarily worried about this one)
I have tested the E stop, water flow switch, all fuses I can find, checked for ground, and ensured I am now using a properly wired outlet
The quick check that stand out to me in this situation are:
If you have mains power to the inlet of your machine, do you get it also on the connections at the back of this. I believe there is a fuse built into that just under where it plugs in.
Do you have main power on the connectors from where the power comes in?
If yes, does that mains power get as far as the e-stop?
If yes, is your key switch turned off?
If no, do you get mains power to your power supplies?
For the LPSU the mains power passes through the Laser switch on its way. If this is OK, is the mains power reaching the LPSU
If the mains power is reaching the machines PSU are you getting the 24V output that supplies your controller?
Update: I have replaced the laser PSU, the controller PSU, and the ruida LCD and controller and some progress was made but still not fixed
I have noticed that when the ruida is plugged into the X and Y axis control modules that the led status light in the controller PSU does not light up. My thought is there is a short or something inside the x and y axis modules.
Searching the net and I can’t find anyone that has had issues with their x and y axis modules and I also can’t seem to source them for replacement. Any thoughts?
You just google laser stepper motor drives. Should be 2 phase drives…I think dc input but you have to .
Probably a bunch on eBay and amazon find out what type of nema stepper it is nema 19 etc…should say on the motor. They’re easily available
I’d disconnect them one at a time at the driver to see if it’s just one or both. Then I’d disconnect just the stepper motor to see if its the driver or motor.
Yes there are two steppers and it does not matter if I plug in one or both, as soon as they are connected I no longer have power at the controller PSU.
