Really satisfied! It's very powerful. Just a quick note: If you want to connect it to your 3d printer, in my case at least, the ttl and gnd wires in the board are reversed. I couldn't get it to work. I switched the cables around and now it works perfectly. I cut these just by holding the laser in my hand and moving it across the surface
I took the laser to make a plane. I'll cut it. I tried it with the test circuit. I haven't installed it yet. I'll set it up when it's missing a card. I bought it on December 19 and December 28
Well, my 20w laser worked well but constantly adjusting everything. So I need a more powerful laser and go to the higher range for PCBs. It's done and here is the monster! 30W delivered complete with the obligatory glasses, the 220v adapter delivered with its EU converter, the little touch of perfection from Banggood. I will have to test it quickly but not in the apartment, The radiation is so intense and the release of smoke from the machined part will force me to go through the workshop with all windows open and strongly ventilated, so that the smoke from the machining does not reduce the laser radiation by blocking the beam. At this power, the environment and the working method must be reviewed and adapted. I will need to install an additional fan on the CNC mobile equipment to cool the laser heat sink. 30W, it heats up hard!
Qualität und Preis in Ordnung.
Very good.
Fast delivery (12 days), strong enough, easy to install
pretty good for its price
Excellent part completely meets my expectations. Works precisely.
Good
a bit of a learning curve but what isn't. It all worked properly and was able to do engraving and cutting with it .
