havent got laser power meter , but the driver is calibrated to provide 4.5A to the diode ( I dont need to run it at 100% though ) this laser driver has a meter output .
didnt realize how easy it is to build my own, too bad i burned cash on that chinese fake one...

Cheers all, bought dummy load board of eBay and verified correct load , also bought diode, LD and heatsink (nubm44) and built my own full laser module
Burns amazingly well and all parts were less than 200usd off eBay incl shipping to Tokyo

thank you, would the best location be to tap into the LD with multimeter or should I build a dummy load to test this ?

thank you, sorry I am a bit confused ,... Shouldn't it be closer to 5a? And do you have any pointers or links that could let me figure if I could do it with laser connected or I have to build a matching test load

Hi guys, sorry if I am not in correct board but looking for some help..

I have one of those 5.5W Chinese lasers with a separate 5a Current Driver ,
Original driver was DOA so they sent me a replacement but I suspect its not calibrated and not outputting the right amount of power.
I would probably say its comparable to 2.5W right now ( I can cut paper on multiple passes at 200/100% and I get very very precise focus and very thin lines , but its nowhere near the expected cutting power of 5.5w)

Focus and TTL was all measured and working correctly on my Mana as well ( I have eleksmaker ttl to pwm as well but tested directly with psu to laser driver too ) , so the last thing to test is the driver board..

It has a potentiometer but I am not entirely sure what would be the adjustment procedure / expectation ... does anyone here have any insight into these ( they seem to come with many of the cheaper diodes ) ...

Is there an easy way way to test it with multimeter and what should I be expecting to make sure my diode gets enough juice.
I have been reading about test load assembly but not sure which one I would need to test a 5.5w laser load.

If that too fails, I would need to get new ( hopefully higher quality ) module ... but rather make sure I tick all boxes before doing that.
the final goal is to cut some 2-3mm plywood and cardboard for my art projects with a bit of engraving on the side.
