I purchased a new 150 Watt laser 3 months ago. (Chinese 37 X 48" bed, purchased through a U.S. Company. Tube says 160 watt) I have been very pleased with this machine (and the company I bought it from) as it did all that I had expected.
I really like this machine for what I bought it for (Cutting shapes into 1/16" rotary cut maple veneer) and all the other projects I have been thinking up. Amazing machine!
From day one the machine has reflected some of the tube energy off the splitter mirror, onto the back case when running. This easily burns through masking tape placed on the case. Company said this was OK.
Two weeks ago it stopped cutting properly at the speed and power I normally run it at, speed 80 and a power of 100. After testing I would say it is almost half as strong as when I bought the unit.
What I have done to try to solve the problems:
- Leveled the bed of the table. It was slightly out and now has a consistent level over its entire surface.
- Changed the lens at the cutter nozzle and made sure they were clean.
-Removed, tested and changed the splitter lens at the ruby red laser, just in front of the laser. (did not help the burning on the case)
-Aligned all the mirrors correctly and cleaned.
-Tested the power supply with the equipment and instructions provided when purchased. (big resistor n such) Lots of power.
The unit has a mA meter built into it. When I first bought the unit when running at 100% power it would read around 40 mA now it will not go over 10mA when running at the same settings but the power supply test seemed OK.
This week the tech told me I should never run the laser at 100%. This was news to me as it is not in any literature I have gotten from them and when I first was setting up the machine tech support said nothing about this. We have a similar sized machine where I teach and they always run their machine at 100% without ant problems.
I am confused by this.
My questions are;
Where did the mAmps go when the power supply test says it is OK?
Is it normal to have reflected energy from the beam splitter hitting the back of the unit?
Is it wrong to run it at 100% power? It does not run continuous during the day when in use.
Any insight on my next step from the form would be great as I am running out of Ideas.
Thanks for listening.

Laser burning a hole in the back of my case.
