I bought their 5.6 Watt laser and laser lens pack. If I could go back I would have avoided buying from them. For different reasons than what Teaching tech described.
What I liked
- Good documentation. If anything they have too much documentation. They have a lot of knowledge and a lot of options. But it got to be a little overwhelming. I ended up just going with an Extrememly simple wiring setup that I love.
- How it was wired. The laser positive power and Signal wires are both connected to + end of a heater mosfet on my control board. Then the laser ground goes to the - pin of the same heater mosfet. I LOVE THIS!!! It is super simple. Makes it so the heater mosfet powers the entire laser.
What I don’t like
- The laser looks like something I could make in my garage. The laser diode doesn’t even aim straight out of build. It points about 2 degrees to one side.
- Their customer service said it’s within “Spec” end of discussion.
- Not all of the mounting screw holes where correctly located and tapped. Again it looked like it was built by a drunk.
- The heat sink for the diode is oriented 90 degrees in the wrong direction. It blocks air flow instead of using it to cool the fins. Instead they want you to mount your own second fan that is supposed to blow across the path of the main fan’s flow.
In Conclusion. I should have either built my own laser using instructions Ryan has provided or just paid my big $$$ for an American made laser. Lots of other good brands out there.
EDIT: Hey I found the image I sent to their Customer service.
You can see the diode points off to the side and That black thing it is mounted to is the “Cooling” fins. So the fan on the end blows air through that square aluminum and around those fins. They recommend that you mount fans on the sides that blow across the black fins. Bad design and poor workmanship.
