I actually read that last night and it did help a lot. And I’ve researched “specs” and read the marketing, and then I read forum posts or other reviews that completely contradict the marketing. And sometimes even the marketing doesn’t seem to indicate any difference.
For instance, the L-Cheapo lasers are available at Account Suspended. Both the 10w and the 5w are described as “It can cut 3/16” wood and plastic, and engrave most nonmetallic materials." So what’s the difference other than price?
At J Tech Photonics, both the 2w and 7w kits say:
Engrave on wood, leather, acrylics, and many other materials! Cut thin and non dense woods like Balsa, Basswood, and thin plywood! Cut many types other materials like foam and acrylics!So what makes the 7w cost $400 more than the $2w? What is the real world differences in capabilities? Does it just come down to speed and number of passes? Because I'm just fine slowing down and taking more passes to save $400.
I understand installation, safety, gcode, and all of that. I just don’t feel like I understand the real functional differences between different power ratings. What can I do with a 7w that I can’t do with a 5w? And what can I do with a 5w that I can’t do with a 2w? Etc.
