- 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
Nice to see you back. Very interesting looking forward to the next one 🥃🥃👍
Very interesting presentation and observations. Look forward to watching all your past and future work!
Thanks for all you do Ross. The knowledge you are spreading is invaluable.
What an outstanding tests and anaysis!? :) Very fun to learn from you. You put a lot of work and effort into the creation of presentation of all these discoveries that we might take for granted. It amazes me that you do all the work yourself. Thanks a lot! Looking forward to another series.
Hi I think effort you put into the labs is excellent this has helped me tremendously and saved me time in my own projects.
Sir i appreciate the way you explained and your patience to make hard heads like me to understand how this actually works.
Very nice. I enjoy your clear, explicit and “common man” quality of your explanations. That makes this highly technical stuff far more accessible to everyone.
Russ, your videos are like a warm, familiar blanket. Thanks for being you. It's not a given. Thankfully you've chosen to be who you are.
Hi Russ... Thanks again for another awesome video...
Great explanation. Your much appreciated by the laser community !
Wow. I have to contradict you. You are a natural instructor . As a technical director at a high school for many years I can say your lecture , drawings and charts were captivating and many teachers would love to have your skill. Thank you as I learned a lot about the optics.
Have a 50W (china watts at least) 4060 Ruida System laser being shipped from Shenzen China as we speak! Thank you for this, great information. Keep it up :)
What an outstanding tests, Thanks for all you do sir.
Great Work.
Very interesting video! Will have to design a jig at some point to do similar tests. Very very cool! Thanks!
Let the adventure begin!
I am very happy to see you
When I bought a 2nd hand Chinese laser with no data on the supplied lenses, I performed a similar test but instead of attempting a narrow beam, I used the manual power to engrave a rectangle on sloped wood. Turned the power down as far as possible while still getting a mark. The theory is when out of focus and at low power the power density is too low to mark the wood. Therefore at very low power, only the area in sharp focus had enough power density to produce a mark. This is how I found the focal lengths of my 2nd hand lenses. I just made focus spacers for the nozzle to work space for the two lenses.
Great video. Thank you.
there are plenty information about cleaning mirrors and focusing lenses. What about cleaning tube output beam lense? (Output coupler) how to do it? Would you do it?
