Important is to read the pdf manual from Atomstack website. The installation of the USB driver is inside the free software, so a normal plug and play like plugging an USB stick does not auto install the device. However my first tries on wood were an success, so I am very satisfied. Anyhow, I will try also some other laser heads on the setup, which seems to be easy to be modified, so great buy.
Dear customer,
