ATOMSTACK A5 30W Test

[LaserJack]

Greetings Laser Masters,
I've been a diode fan for some 5 years now using ELEKSMAKER A3, A5 machines with the 2.5W Laser heads. I finally decided to upgrade? and took my chances buying a ATOMSTACK A5 30W (5.5W output they say) laser machine on Banggood. I know - you professionals always say DON'T TRUST THE CHINESE STUFF! I received the machine on 25 Feb. 21. I tested it today for the first time using T2Laser and Lightburn. To my sad surprise the suckin thing would not even cut black matt card stock or paper with three passes at 700mm speed and 100% power!! Boy was I am happy camper!
Of course the Manual that came with the machine is only for assembly. I downloaded the User Manual. And I watched DINGs YouTube Video

Also notice the attached photo: the laser light burns differently when it travels horizontally versus vertically. Hmmmm?

Nothing helps. I sent a complaint to Shenzhen ATOMSTACK Support today with pic and video. Let's see what happens!
Have a great weekend!  LaserJack Switzerland
