RDWorks Learning Lab 102 Laser Beam Diameter

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

Better than a Cadbury Egg in my Easter basket.  Thanks Russ for a very informative and professional video.  Perfect timing for me to tune up the Chinese dragon.

are the mirrors in these lasers under sized. what is the diameter? If the mirror housings can be changed or adapted would bigger mirrors be an advantage in using the far extreme of the beam.

Good evening! First of all congratulations for your videos. My name is Nick and I am from Greece. And I recently bought a Chinese laser. Your videos have helped me a lot but I have some questions. 1. I try to connect the machine to a tablet which runs windows 10 but do not recognize. 2. When cut a piece of wood or acrylic, on two of four sides are side cut and there can align the laser. 3. When sever few stencil paper at a speed of 400mm / s when the head rises TO TOP does something zigzag. Can you tell me what can I do; thank you very much!!!

Explain to me, if you can because I don't know the answer, but I have a laser pointer (5mw) and when I pointed it outside my window to an object 50m away the dot had grown pretty large. Is this because it is only 5mw or what is going on? No mirrors for distortion so stumped I am.

Russ. have you ever tested the divergence of the beam from the output lens. I believe the standard tubes are actually divergent. I noticed this when testing a tube with a target 3ft from the tube the burn was much bigger than at 4" I currently run my machines with the exit windows around 30mm from the first mirror to minimise any divergence but I've not actually measured the difference between 30mm and say 60mm in relation to beam width.

Been following your vids for a you comment, maybe in a future video, regarding laser safety. I don't see you wearing any goggles or taking any special precautions against stray reflection and your eyes. I'm just looking for info to assist the use of my own 40W laser. Thanks, Ian.

Hi Russ. Over the last few months I have spent many hours watching your videos, I owe you a huge thank you. I finally received a squashed Chinese laser printer. I know this is off topic but the chassis is twisted about 10mm. Looking from the front, the black chassis rail and the laser head bearing rail have a 10mm twist. The seller assures me this can be fixed. I disagree and demand a full replacement or refund. Am I being fair? I can email a photo if it helps you understand what I'm trying to explain.
