laser beam not burning 1st mirror

[Grimreaper831]

Hello all, I am a very new newbie and looking for help with my laser machine.

I have a LC9060 and had to replace the laser tube. Have followed everything but when I press laser, the laser tube fires up but does not burn a dot onto the 1st mirror reflector.

I have tried checking, feeling very frustrated :-(

I hope someone can help me.

Thanks,
Amanda
