newbe needs help with china laser

[LandorKippi]

I just purchased the ENGRAVER MACHINE 60W it took me all day to figure out how to get my computer to find It when I finally got it working the laser seemed weak I put it up to 90% and it wouldn't cut through 1/4 in acrylic it would jus barely break the surface. well I was trying to make a few things to try it out and it just shut off and hasn't turned back on since. I tried to see if any wires were off or burnt on the inside and it all looks normal. what can try? the manual has nothing like a troubleshooting guide in it

There is a fuse in the back by the power cord, its inside a plastic holder, try checking that it may have blown.

[Haroldabag]

You should check if mirrors and lens are clean and also the light path

[RodolfoWen]

You can loose 90% of the laser's power if the light path is not correct !

if it was the tube wouldn't the whole machine at least start up it is completely dead I was making something and I thought it blew a fuse because it completely shut off but the fuse wasn't blown I tried other things in that outlet and they were ok

You checked the fuse in the power socket on the machine? Mine has a fuse in the socket.
Any power board/strips in use with over load protection in them?

i have that machine, plugged all the accessories into the back, it burned up the main switch, so i put everything on a power strip, and jumpered the main switch, it was only rated to 10 amps.
have since replaced the main switch.
now i want the password for it to check it hasnt been derated
