Laser turning on but not making a dent on anything
« on: January 05, 2017, 03:41:20 PM »
I looked through the trouble shooting and haven't found another post about this particular issue, but maybe it's because I unknowingly burnt out my laser when I first tested it out. :-\

My problem is that while everything else seems to be working fine, my laser is turning on but not burning through anything, not even making a dent when I put the power to 100%. (I recently purchased the 5.5w Eleks laser machine.) I installed the BenCutLaser and T2 software, and used the line tests and nothing works. I'm suspecting my laser might be defective, when I focus the laser there is a circular lens flare around the laser beam, so maybe it's not focusing as much as it should be. Any suggestions at this point would be greatly appreciated!

Does it have a focus lens or is that a fixed focus laser?

It's worth removing and replacing the lens, it may not be installed correctly.

My 5.5W unit has a weak laser button to the circuit board mounted on the heat sink.

^ this... if the switch is pressed it attenuates the output.

It has a focus lens. I will see if I can remove the lens, I'm afraid of taking it apart but I think that's how it's going to go.

I tried putting it in the 12v fan and it does turn on but same problem as before, it's not strong enough. Would that be because of the Mosfet? (What exactly is the mosfet by the way? ???)

Are you referring to the weak laser button next to the power button for the motors? If so I have it switched off.

OHH okay, that button was turned on. I turned it off, and it appears to be working now! Thank you so much! ;D

Glad it was something simple, ggallant571 gets the credit.
