Genmitsu Compressed Spot Laser Module with Air Assist Nozzle, 0.08mm*0.05mm Laser Spot, for Genmitsu 4040-PRO CNC Router, Jinsoku LE-1620 & LC-60A Laser Engraver

I had connected the wrong cord and couldn’t get it to work. Customer service told me to use the cordThat didn’t flip the wires and it worked great after that!

The first unit I've got didn't work properly. I think the nozzle (air assist) was not machined properly. See the comment from another user that had a similar issue and he solved the problem by enlarging the hole in the nozzle). The laser ray was hitting the nozzle and as a result it reflected the light randomly. Ultimately the laser was not focusing properly unless I took down the air assist.The second unit worked out of the box perfectly (with the air assist on). Although the first didn't work I gave it 5 stars because:1. Ultimately it worked as expected (errors happen sometimes but as long as the manufacturer fixes them, it's not a problem)2. Customer support was very responsive and offered to replace the unit right the way. I found them very professional3. The laser is well integrated with the 4040-PRO4. You can cut 11 mm plywood and 3mm acrylic (coloured) without a problem. For a diode laser you can do quite a lot. Don't expect high power and CO2 capabilities though5. Complements the entire ecosystem (4040-PRo CNC machine, 4th axis) quite nicelyOne observation, the support team said there is no pump for this laser offered by Sain Smart. That is very strange because I found that Genmitsu pump: https://www.amazon.ca/dp/B0BKGFSQC3 works just fine with it.

UPDATE: As I expected, the new replaced unit works great. I hope the defective on is recalled and not sold to anybody.---Spent the whole evening trying to make this one work but with no luck. Bought this as an upgrade for 5.5W module that worked great but I needed a more powerful laser now.The 3-pin connector and all the wiring is correct, I check the back of the PCB of the laser for 12V, GND, PWM pinout. Using a 12V 5A power supply. Fan is on and laser reacts to LightBurn. Yes, everything is set to "Laser MODE" with $30=1000, $32=1. PWM signal is also correct, that is 5V @ 1kHz. I can see that with the oscilloscope and the duty cycles changes accordingly with G-code commands.With G1M3S1000 I do get a solid +5V at PWM pin, with G1M3S500 around +2.7V that is ~50% duty cycles @ 1kHz.However at 100% power it is much much weaker than a 5.5W laser.At this point I believe I received a defective module and ordering a replacement (returning this one and buying the same).

this is updated review.I gave only 1 star in the beginning due to the power is very low. and Tech support did not responds for a week.After tech support reach me, explain they have trouble receive message in their system, the communication become much smooth. Joe suggested me to change the $30 = 1000. I am a beginner, I wont through the max spindle speed has anything to do with the laser power. And this is not motioned anywhere in the document.So, after change the $30=1000, $32=1, the laser is working perfectly.I now can cut 5mm pine plywood in 1 pass (speed = 300mm/s, power = 80%)
