If you own a Chinese laser cutter this little series of videos about me learning how to use the free software provided, may solve the problem of trying to learn from a virtually unreadable manual.
I am nothing to do with RD Works, I am not an instructor and I am no expert. This series will document the essential bits of many hours of trial and error

To access the drawings and purchasing data mentioned in this video you will need to visit rdworkslab.com or 3dpassion.com where they are free to download. there is also a pdf document of useful information that you should read. There is a ready to run .rd file for Z axis targets if you have a Ruida controller or a DXF for those that want to adapt this for another machine.

$RDWorks Learning Lab 246 SPHERICAL ABERRATION. Our New Best Friend I have made several videos documenting my discoveries about the relationship that laser beams and lenses enjoy. Normal optics is well established for telecopes , cameras and microscopes etc These products use glass lenses to focus regular light images. Laser light obeys all the same laws of refraction that govern lens design but the non-uniform intensity profile within a laser beam sets it apart from normal light and the age-old predictions of lens theory about what happens after a focal point are no longer valid. For laser cutting, the beam stops at the surface of the material (usually the focal point) and light energy transforms to molecular kinetic enegy to effect material damage. There is no after the focal point as described by normal lens theory because we are not transmitting IMAGES. I have spent several years experimenting with lenses and laser beams in an attempt to understand the mechanism that allows cutting to happen below the focal point when conventional logic predicts otherwise. I reached an understanding of the basic cutting mechanism several months ago, but recent research into spherical aberration has allowed me to fully understand the many damage profiles and unanswered details I have obseved during my test work. I feel I have now fully masterered the many interwoven factors that allow this cutting miracle we all take for granted. I have created a PDF document called The Dark side of Lenses that is the basis of this video. it is a synopsis of my 3 year journey searching for this mechanism of cutting that I was unable to find described elsewhere. Hopefully it explains and demonstrates the many jigsaw pieces that build to a final picture.
