Sir, respectfully, I have a technical question. A lot of the lasers light is waisted in an open beam. You can always see the beam, given proper optics. That light is wasted. Unless you focus the beam near infinity, then cram the beam into a fiber wire and take all the normally wasted light to increase the density of the beam. What happens without the seed lasers??? Think of it this way. Your holding a high-powered pointer thur a magnifying glass to its smallest point on to a glass top table. What do you see the laser looks like on the other side of the glass...Super diffused. That doesn't happen in the fiber. No room to diffuse. It harnesses the light that would normally be wasted, and it does that from 16 lasers. Not a capacitor, its a barrel. Could I be right?

Another vote for spindle turning counter-clockwise, he should check that! Also what about bad bearings in the spindle, could the shaft have excessive up/down play??

Are you able to thread on the cnc mini lathe? I would think in order to thread, your cnc control board would need to be able to read spindle rpm. And I don’t believe your mach 3 breakout board can.

Thank you Roger for the upload. I am going to buy one soon! 👍👍👍

Thank you for the upload Roger. You have saved me lots of cash!👍

Many thanks, was trying to figure where the Earth terminal was, you made it clear!!

Thanks for showing Roger People who have these type of machines with Nylon gears must understand that they have them as a safety for the Novice/beginners meaning if you get jammed up the gears or cogs can break instead of burning out the motor or circuit and so on for the more advanced user then you can buy metal gears and cogs to upgrade Also to say the Nylon parts cost almost the same as metal parts so its not about making cheap for production, but to help the armature be safe

Hello Roger, I di Not understand why the diodes have to fire in sequence. Couldn't they fire simultaneously? Thanks

Thanks Roger top work much appreciated 🤝🤝

G'day from Queensland, Roger you do agreat job in your in the videos I have many questions as I'm new at this kinder work. I have built a cnc router. Can you or any one else tell me where to obtain long lengths eg 1500mm lead screw. Keep up the great work

nice video. one question.... using windows 10 and db25 bob it is usable with a pcie to db25 adapter card? thank you in advance for your answer.

thank you this clears some stuff up. the one I am attempting to replace is for a vacuum. This would be my first vfd replacement ever. the VFD from the OEM already setup is $1500, but, I can get a new one not setup for 250. and there is an identical one next to the broken one and is working.

Good, I liked't

thanks!

Thanks for this, pretty important to have that earth if something goes wrong. Had a look at that shiny Sainsmart one thats around 159 and it does have an earth on the power connector. Also it uses er11 collets so should have more compatibility .

it's about oxide affect on surface of metal, and i have a question: what is the source of this engraving machine? is it Raycus?

👍

What effect does increase or decreasing do? Does more speed mean a smoother finish or just quicker material removal?

Love learning from the elders Never had a grandpa or dad to teach me any type of work men do Always self taught and learning from men like these and wishing to pass down to my son and daughter and future grandchildren

Were u able to make any improvement in the marking on wood .. with fiber laser

Very detailed and relaxing with the exception of the barnyard choir in the background.

I'm in the process of making a manual bridgeport style mill into a cnc. I'm almost into the wiring process. Have to order all of the electronics for it still. Thinking of mach 4 because in the future I will want to run 5 axis. My question is how bad are the glitches

Thank you Roger I look forward to watching the detailed video on Mach 3 and the Queenant Pro V2 🤝

I'm happy i solved the patron's issue 🙂

This was one of the best presented DIY videos I've seen on nearly any subject. I felt I was almost just learning it in person.

I agree with not running in the right direction..

Hi Roger I have bought a Queenant Pro V2 and have a Gecko G540 with Mach 3 could you help with the motor tuning with the 1610 ball screws and Nema 23 345Nm steppers. I am coming from a Open builds OX Belt drive ? Cheers Peter

Re: aluminium - the patron should check if it cuts with no lateral movement i.e. does it drill with the bit? Secret to aluminium: single flute, up cut, cutting fluid, ramping. I built a large CNC doing this on my Heiz S400, a great machine but nowhere near as beefy as the Queen ant

A stupid doubt. Is the patron's spindle running in the right direction (FWD and not REV) ??

Thank you Roger for your video. I've worked with HEL's since 1973. I even got to play with ones used in the "Star Wars" projects (ABL). But I never had a chance to do any design of a fiber laser system. Please answer me this. Is the fiber used in the amplifier doped, and if so with what? What are the amplifier's absorption and emission frequencies? The oscillator laser diode operates at what wavelenght? Do you have any energy level diagrams and the timing and energy levels that are involved. Thank you very much for your time and help. Mike J.

6-2024 funcionó perfecto

Video is great. Thank you. Could you explain a bit more how seed laser diode is initiating an laser beam to be released?

Do you have any experience with the newer k40+ OMTech lasers I am having issues with mine burning traversal moves as it moves shape to shape on the wood how can I fix this if you know how to

Do you know what the total price is for the parts? or do you have an rough estimate within a reasonable range? Because if it’s in my price range I will be getting it off your Patreon! Nice last name by the way!

good work and nice choice of your background music. ahead of 99% of youtubers out there.

I'm from India

Hi

Great! Speaking from personal experience, I've been utilizing the Monport laser machine for several months now, and it's been a game-changer for my projects. Its user-friendly interface and reliable performance have made laser engraving a breeze. If you're considering investing in a laser machine, I highly recommend giving Monport a try.

Hey, this is a great thorough walk through for wiring a steer driver/motor, would it be possible to use a mach 3 board and run duel motors on each axis?

Tungsten carbide drills?

Great explanation! What if you used 16 CO2 lasers to produce the pulses instead of the 16 diode lasers.

Hi, i had the best result of color marking on Steel and stainless Steel with my JPT Mopa M7 100W if i use the following parameters: Frequency 800kHz, Speed 2.000mm/s, Power 10 to 25%, Q-Puls 15ns, Hatch 0.0005 to 0.01mm. I use a 210mm Focus Lens. Color Marking into Focus.

What is hatch

Could a laser like this be used to deep engrave a hex shape in the head of a custom bolt to use a allen key in it?

Have you ever had a chisel take off like a bullet? I have a Norfolk Pine that we will be having cut down soon and I am thinking about buying a lathe and giving it a go, but I have already had a router bit from a router table whistle past my head so it is a concern. But apparently Norfolk Pine can make some awesome bowls and not a very common wood to find.

Very nicely done. Jope you didnt hurt yourself.Like you siad, that was a ricky one. beautiful piece for the house or a friend.

Very helpful. As always, thanks

I have a collection of focus T's cut on my 80W CO2, one for each lens 110, 175, 220, 300 for the Fiber and 110 & 220 for the UV. I have a couple of others for specific lenses for things like Z-Mark on stainless as well. The 300mm lens on the fiber is pretty darn long, but what I tend to do is cut them 5mm longer than I want, and then once I follow the same procedure as you did in this video,. I use my bench grinder to slowly shorten the focus stick to be the exact length needed - that way any errors in cutting, even by just a mm or two, is negated. Oh and then I can label them on the UV so they look nice and pretty too lol

I am really interested, but the music whining away in the background makes it impossible for me to stick with it.

Is there a supplier in Australia
