Hi Dave,
Sorry forgot to mention I have a shenhui G460 machine with CW-3000 water chiller.
Don't know where this is.Flow switch?
No Door switchDoor switch?
Don't know which specific wires. Please see pictures below.Trigger wire to the tube PSU?
Could be as this is where the problem started as I said above (was able to cut several acrylics - turned off key switch - changed acrylic sheet - turned on key switch - pressed Laser button - suddenly wont fire). But I checked and wires are properly connected.Key switch now faulty?
When I fire the laser before, I can see magenta colored beam but now nothing.It's unlikely to be a tube fault (there are other symptoms when a tube fails) but could be one of the above.
- not sure which of the images below is the mainboard but as for the laser tube power supply, I am trying to open it (stripped the last screw, still trying to open it), and check if the fuse is blown. The fuse for the two 220v plugs are fine.Check every screw lock that holds a wire on both the mainboard and power supplies to ensure they are clamping the wires correctly.
I am not sure if my machine has a door switch.Place a strong magnet (NdFeB if possible) on the door switch (if it has one) BE AWARE this will bypass the door safety lock, KEEP ANYTHING and EVERYTHING out of the machine working area when you test fire it.
- I believe my machine does not have a water flow sensor. I checked and the water is clean.Locate the water flow sensor in the machine (if it has one) tap it lightly a couple of times to ensure the flow bobble isn't sticking. (also check your water supply for signs of dirt or junk, this can make the flow switch block up and cease working)
Thanks Dave!If these don't work drop back and we can go into a few more things
Did I mention:
Leave the machine OFF for 6 hours first
Keep anything you don't want destroyed OUT of the working area of the machine.
cheers
Dave
