qr code marking,recommend RFH 3w 5w 10w uv laser source with water cooled and power

customer reviews 

The laser marking qr code itself is of fairly high quality, you can see where they made compromises, and that in of itself is acceptable because a similar machine in North America goes for more than 20,000 USD. There is always a trade off, and knowing upfront that a compromise is made in one place or another upfront is important. The mechanicals, stepper motors, rails and drive systems all look great, I had my friends who are machinists go over the mechanicals of the machine top to bottom and they couldn't find a technical fault so far.
