I have just set up my used red and black 60W laser.
The person who owned this machine gave me a demonstration of function before taking possession then removing laser tube for transport.

The laser tube has been reinstalled, chiller set?, exhaust installed.
I have not tweaked the mirror alignment yet.

The problem... The pulse function works fine on low or high power but when I run a program I can see the laser tube firing but nothing comes thru the mirrors or lens or no marking.
I have placed paper in front of the mirrors and they mark with the pulse function but do not mark when job is running no matter the power setting.
