Russ every time I watch one of you videos is a journey Into another discovery. You have been a great inspiration to my involvement and encouragement to get my tools out and start making changes. Thank you for you inspirational drive and en less energy. TainoWorks Crafts, Springfield Virginal USA.
Hi Russ, Thanks for taking the time to make all these videos, they're so informative! I can't seem to find the files for your video on either website listed in the text. What post should I be looking under on the rdworkslab website, or what search term should I use on the 3dpassion website? Thanks.

Hello Russ!! I would like say thank you for all the videos and great information. I am in the process of getting my 80 watt China Laser,and I would like to ask if you would send me the information you have mentioned on your videos for the test programs and 254 Test Program. I would like to ask,if an 80 watt laser is to much for engraving on all the material you have been working on? Thank you Sir.
Hi John If this is an Ebay 80 watt machine, the chances are that in reality it will be a 60 watt tube. You need power for cutting but delicate control of power for engraving, especially dot engraving. You will lose that delicate control with more powerful tubes. 60 watts is the ideal compromise for an all round tube but if your tube turns out to be a real 80 watt tube then don't panic because you will still be able to do dot engraving but at really low power settings where the degree of control is a lot coarser. If you attach your email to another comment, I get auto copied to my gmail and will send the dot pattern. I will also delete your comment/email from public view. est wshes Russ
Hi Russ....Peaked my interest again, but probably not for what you think. Nosey me would like to ask, what is that above your head in the rafters, red bottom, and looks like it has rubber feet?

You mention the power supply not being the original one, did I misunderstand this or did you buy a better on, if yes, which one? Thanks btw for the long reply regarding protection and goggles, could not find the comment again though, was it removed? Best regards
He did not long after he had the machine. He made a video about it, and showed how to install it, because when he went to a 60 watt tube his blue turd of a power supply was the typical blue turd 40/50 watt that comes with the China blue machines. He was amazed when they sent him a 70 watt tube etc... He can post a link, if he wishes, to where he got them from but they came from an AliExpress store and is a good laser supplying company (not AliExpress the one he bought it from that starts with a M I believe).
Hi When I upgraded to a 70 watt tube I replaced the power supply also. I was very naive when I bought my machine and did not realize I was buying a reject tube and a B grade power supply. The first few months of my videos show me fighting with the obvious low power from my supposed 50 watt tube.. I replaced the tube from an Ebay source and again, in my naivety bought another B grade tube. It was shortly after that That I invested in a power meter, proved that I had been duped and then decided to upgrade to 60watts. That meant I automatically had to upgrade the power supply. I always had doubts about it and it was not until I started to get lots of correspondence from people around the world that I saw the pattern of C grade tubes and B grade power supplies from Ebay sellers. The usual problem with these power supplies is that they have a very poor response time. They work in general for cutting but this failure to make the promised specification causes them to be unwarrantable and therefore reject. This performance deficit causes a poor engraving characteristics. Yes I did delete your comment because i never feel it's wise to leave your email address in a public forum.. Best wishes Russ
btw, his power supply is the one I went to as I still use real 40w tubes but my power supply is for 60w. The MYJG-60 and it has an adjustment screw on the side so I made it that 100% power was 18ma which is the max a 40w tube likes and beyond that is over driving it. 50 is 20 and 60 is 22, etc... It made a HUGE difference and has one helluva fast response time that the blue turd could only dream about on its best day.
Yes the sharper looking picture on the right was dithered and done with the normal ON/OFF dot scanning method. The picture on the left was also dithered but done using the greyscale power variation method. The dot picture on the right would have truly popped if the original picture resolution had been higher. To get a good 254dpi resolution picture you need to start off with at least a 300ppi image. The fact that it was originally a 72ppi picture up-scaled to 254ppi meant a lot of information in the picture was "invented" . However it was adequate to compare systems. The 80% result was pretty good but when you watch the refinements in the footnote video you will see I got close to 90%. This is NOT a dead approach to photo engraving and I will be looking for ways to refine it in future. Best wishes Russ
@@thebeststooge Hi Yes your original wasn't an myjg..... but it could have been. The slow response time from a power supply means it cannot be sold with a warranty claiming it meets the less than 1ms response time. Hence it gets dumped on to the "repurposing" market and ends up in Ebay machine. They work ok for cutting where response time is not an issue. Best wishes Russ
Know what is funny? When I had a blue diode laser I was doing exactly the same as it was not ttl so if I could make it turn on it would have the speed I needed once on so I had a helluva deja-vu session this morning with this video. edit: btw did you change your internal settings as 600mm/s is over the max they set and to be honest I tried this and no difference in speed under the old belts when I adjusted it so I am not sure if we can really do 600mm/s or not on these machines.
This all goes back to my trip to Florida 18 months ago, when I met Chip Williams. I never forgot his words about "once the tube is ionized it has an almost instantaneous response time." It had no relevance then because that only applied to RF tubes. It's staggering how the brain works sometimes. I was explaining the stupidity of spending mega money on an Epilogue machine to a young lady here in the UK, listing the pros and cons when in a millisecond I saw what took me almost an hour to explain in my video. Out of nowhere all the pieces just lined up. After completing my email to her, I quickly rushed out to my workshop to prove the principle.......... and failed totally. What had I done wrong?.......the idea would not lay down and die. I an planning to do a session where I play with the tuning of my X axis now that I have removed a lot of head mass. I genuinely think I can double the original speed to 1000mm/s. Then we will see if this greyscale dithering technique holds up. 90% dotting quality at 5 times the speed must be attractive to those people in the "engraving while you wait" business. Best wishes Russ
I am just not sure we can get 1kmm/s out of these non servo motors. If we can I would be delighted as I have seen a real servo doing 1000mm/s and our machines are standing still in comparison.
@@thebeststooge Hi You are absolutely correct if I do manage to pass through the light barrier at that speed I wonder what the engraved finished result will look like???? However. I am seriously go to try for 1000mm/sec.in the X axis.
If you can achieve Warp 1 that you can verify is really Warp 1 please post any results you hit upon because just being able to actually hit 1000mm/s on a non servo system is a feat unto itself and the icing on that cake is if it can engrave as well. :)
