In part 2, I show the gantry and beginning stages of the frame build, mill some custom servo motor mounts, attach the homing switches, and share some updates on the feedback from my last video.
I've been working on building this DIY 1000W fiber laser cutter for the past 6 months and I've finally reached the stage where I've begun successfully making test cuts with the machine. Because I could not find any guides on the internet to help me with the build, I am going to create a series of videos sharing what I've learned during the process. Please understand that I am a novice on the subject, and that fiber lasers can be very dangerous, if you are going to build or use a laser, please do your own research and understand the safety risks!

Just got showered after a good long hard day of work and I see this posted 4 minutes ago, nice!!
1:19 plus minus 18cm but nice! Awesome project :)
What I'm really excited about is part 3 which is hopefully about the laser :)
Pew Pew [mandatory laser sounds]. Yes, part 3 will hopefully have lots of useful tidbits...
before he did have a list on all the parts
the laser source can be sourced from alibaba for around 6k€ i think
So excited to see this build come together! good work and keep it up.
Man this series is badass.
I own a machine shop in Largo FL. I was quoted 120k for a 4000 kw laser. Your telling me for less than 20k I can have a 2k laser? madness!!!
I'm digging this series! Keep up the great work!
Been super excited for this part 2, I almost started on a project like this a few years ago and it is really cool to see what might have been.
Another amazing video. Thank you for discussing the gantry setup that you purchased and your opinion on its performance. I had not thought about a pre-built system to start with. Great ideas! Looking forward to seeing more on the driver boards and software in future videos. Thank you for sharing with the community.
Please keep them coming. Some day I will be living your reality with one of these.
Awesome Project. You have reached where no maker has ever dared to go.
My favorite project out there right now.
Really Incredibility, More detail in Next Parts Please!
So Amazing Project
Travis, I've been looking for several years for someone else to do this too. I've been wanting to build one and now I think I will. Already built CNC router, Plasma table, and retrofitted an older CNC milling machine with new controls. Keep it up!
Awesome! Can’t wait for the next video.
Absolutely brilliant!
If you keep having wobble trouble, i can reccomend some triangles in the frame design, just a few should do.
Good call on swapping those casters. You're making me want to get a laser head for my router.
Thanks for video. I'm waiting part 3.
I'm looking forward to the other parts.
When the project videos are fully uploaded, maybe it will be a guide for the laser I will make for my own workshop.
I found yoir channel becsuse i jusy watched a guy who built his fiber laser from a plasma cutter.
I am impressed with your work 👌
Watching from South Africa 🌍
Thanks for the video. Enjoyed it
well i have to throw a quick thx your way , the minilathe and mill upgreade and this build pushed me anlong with 2 friends to build a diy 5 axis cnc mill as my grad-project for highschool, we're aiming around 6k (since i wasnt going to pay that for the pocket nc) in cost and hopefully will use the masso g3 touch (sice i heard only good stuff) hgr 20 rails, sfu1605 ballscrews etc , you got me hyped🤣
Finally someone is doing a laser fiber.. Been looking for this for the last 3yrs..i really dint Want dive in such a project without prior knowledge and make mistakes with such an expensive hardware..
Thanks again for the second video. It's very tempting. Maybe if I can get out of Kalifornia..... lol I was thinking this might be a good add-on to a CNC I have for additional work. I have a 5'x10' AVID CNC. It only has 8 inch clearance from the gantry to top of the work piece, but could make some room to go below the frame.
All I can say is OUTSTANDING 😎
Good job Man, greetings from poland!
Congratulations awesome machine and tech
Please keep up with posting on the project😀
Holy moly this is Awesome!!
Acompanhando atentantamente. Obrigado pelas informações.
FWIW, it's much stronger to ditch the puny cast angle brackets and just use core screws - it's cheaper too - you do need to drill and tap of course and drill through the outer extrusions, but you end up with a much more professional and infinitely stronger job - and no brackets in your way if you need to fit infill panels. The downside is that you don't get the Meccano effect - you can't move the parts without re-drilling the outers :-) Great project BTW !!
i'm sure you're aware, but you can calculate the critical speed of a ballscrew (at which it will start whipping). for my cnc machine i had to go with 25 and 32 mm diameter ballscrews because of the length and bearing arrangement
I import and build Chinese fiber lasers. 200psi air is good, just increase your volume with a second accumulator tank to increase run times. Chinese machines typically use 1.6Mpa which is 236psi. Then a dryer which is just as important as the air flow. Oxygen uses a dual nozzle 1.5-2.0mm air is single 1.5mm Nitrogen/oxygen vs air is slowing down for air same focus/power. Your Coro and wood is going to burn when you have a failure to pierce. You need a enclosure when you have people without safety glasses on in the same room. You alone will only have to deal with burning slag hitting you. With manual height you can cut wood, opaque plexiglass no problem. Fiber is metal only because the auto height is capacitive/induction based. Get auto focus height bm120? Has nice interface. Nitrogen is $40/hr oxygen is 0.60/hr Air is 0.40/hr We cut 3/16" carbon steel all day long with air with no burr at 236psi. I have some tube cutter video on my page 2" 4" 3/16 square air 1.5mm single nozzle, 0 focus height. Put a piece of aluminum in your tray bottom to be a sacrificial material and absorb heat.
good job
If you have a welder, it's much cheaper to make the basic frame out of 1" steel square tubing instead of extruded aluminum.
That part doesn't have to be perfectly square like the gantry frame.
Use the expensive extrusions where you need the slots for re-fitting or making precise adjustments.
Use steel tubing for cheaper framing that needs to be rigid, but can be less precise.
People over-use aluminum extrusions. It's great stuff to work with, but sucks to fork out the money for it when you don't have to.
Check out the RatRig Stronghold pro sounds like it has what you need
00:04 Using 16 gauge carbon steel, created brackets for enclosure.
02:04 Use of supplementary videos and discourse forum for additional information and assistance
03:12 Considered bulkman 3D ultimate B kit for the laser cutter but realized its limitations
04:22 Assembling the gantry and frame
05:27 Custom adapter plates and motor modifications.
06:48 Upgraded z-axis motor and designed mounts for homing switches
07:52 Wiring up switches and mounting the laser head.
08:56 Purchasing high purity gases and cutting parameters
Crafted by Merlin AI.
Freaking awesome!!!
8:55 we buy N50 (same as yours) purity nitrogen for about 30 €, Ar and oxygen for a bit more, 40-60 €, even N60 Ar costs less than you paid for N50 nitrogen. That prices are rip off.
Or sales person was not interested in selling a single cylinder so he just told you the price that make this sale reasonable for the supplier. And I understand them too.
For better speeds, I would recommend a rack and pinion drive.
Suggestion: You should replace the couplings with zero-backlash ones. Quite the standard for servo-motors. I'm also not a big fan of the standoff mounting. Any industrial application would have an adaptor with a housing. With all your equipment it should be easy to make. Acceleration is where the servo shines due to it's very low inertia. I suspect the standoff bends under peak load. The tube adaptor also provides a centering shoulder guaranteeing concentricity. Must have.
these types of couplers _are_ zero backlash. acceleration is not where a servo shines; it shines in constant torque over a large rpm range. low inertia does not inherently mean good acceleration; it's a function of inertia, torque, and power
@@ikbendusan What is used is a curved jaw coupling which is different from a zero backlash type. The zero backlash type is more suited to servos due to its high torsional stiffness.
You do not need a servo for constant torque. Any AC motor with an encoder in closed-loop is really good at keeping constant torque.
It is true the servo has a great RPM range.
Compared to an AC motor, the servo has a much smaller inertia therefore can get faster at the desired speed.
Holy crap that thing you built in a home work shop can cut 12mm 👏👏👏👏👍, I would love to build a 1m sq rig, will be interesting to see what the diy costs will be.
Have a look at the first video in the series, I give a price breakdown there
great video, i want use fiber laser 300w for cardboard project i want to know if i need gas also
Respect!
What controller are you using to drive the table?
Great videos! Thanks! btw it is 20 millimeters :)
Cool!
If you want speed. Just use belts insted for ballscrews. Will also save you some money.
Lasers dont need the rigidity like CNC milling machines.
Just an FYI: centimeters ≠ millimetres 😉
Are you confident in manufacturing small shop laser CNC. I tried to buy one with a small footprint, but it is just as expensive as a larger one. I been looking for one that will just hold my welder/cutter
Ah yes, either buy the ultra high purity or if that's too expensive just use oily wet air from a small DIY type of compressor. Somehow that does not look to be a proper alternative.
What would the "LaserPlus" type of gas cost instead of the UHP ? It looks like this type of gas was specifically made for a laser thingy, possibly even a laser cutter. By the way, it might be an idea to go shopping at different companies for gas. We used to pay almost 3 times as much for a cylinder with regular Argon as we do right now for Premiun Argon.
I love these machine casters by the way. Wheels on a machine are great for moving it around but it should be placed on steady feet when being used. These machine casters have built in feet that you should use to get the weight off of the wheels. This not only makes the machine more stable but also prevents flat spots on the wheels, which makes them quite unusable (don't ask me how I know ...)
Haha, that’s a good point! … actually the compressed air went through 4 filters and 2 air dryers, so hopefully it was pretty clean. I tried to purchase the LaserPlus variants, but apparently they don’t make it anymore. I’m definitely going to shop around next time!
@@diyfiberlaser Ah yes - now I do remember that you showed this (I think that was in part 1). Having clean and dry air without particles will at least save your equipment, prevent corrosion and clogging of internal filters and valves.
Whatever type of oxygen and nitrogen you get, most likely any of the industrial bottles gasses are better filtered than your own shop compressor air.
The reason for the high purity variants is to get the best results without any slack or contamination on the edges that were cut. You will see an improvement when going from shop air to the industrial gas but then going to UHP gas will only give a small improvement that you most likely will never notice using standard sheet metal.
@@Rob_65 yeah, I don't have experience of laser cutting, but I believe that N40 or N60 will make no difference at all in this case. Because it's not closed system and supplied gas mixes with ambient gas, I'm very sceptical about the idea that even N50 purity could be preserved in just a jet of gas.
I need to cut 1/8" Aluminum. What do you think about building one?
Is this laser cutter useful for PCB stencil making?
What is the total estimate of the build just, will like to start this project.
This is going to be my very first every patreon. Great Work.
He gave the cost in his first video, iirc it was about $15K.
He overspent by a huge margin on a lot of stuff that only aerospace would normally use.
His rig is small enough that it could probably be belt driven since it does not need the rigidity of a mill or router.
Even with premium motors and drivers, you should be able to build the entire motion control system for under $5K
Woop woop !
I've successfully cut 0.7mm think stainless steel with my 50W Raycus galvo fiber laser engraver with a 150mm lens.
With your 1000 watt fiber laser what thickness of metal can you cut/
Nice build, especially when you dont know the difference between millimeters and centimeters
Have you found a solution to not using nitrogen at all? Is their a way.
Do you still have a day time job? I am in the process of building a co2 laser but with work and family and the cost factor there is only slow progress 😀
Yeah, tell me about it. I'm working on fixing up a huge CNC mill I hauled into my garage (or more accurately paid too much for someone to forklift into my garage). It's been VERY slow progress...
What's with the "20 centimeters" thing, again? Wasn't it 20mm ??
Why did you use servo motors? Wouldn't it be cheaper to use steeper motors (and drivers)?
Servos are known to be fast and precise than steppers
Also stepper tend to loose steps in high speeds so it is not practical for such project
💪
How much would cost for all the parts needed ? DIY
See video #1 for cost info: ua-cam.com/video/o-eVTnO0tFM/v-deo.html
What’s the cost?
Fill your aluminum extrusions epoxy granite ...you machine is shaky
THC in bottled nitrogen? Who knew? Where can I buy the high THC stuff? LOL!
Travis ok?
1:16 That's not 20cm... That's 20mm or 2cm. 20cm is 7.9 inches. :-)
L I K E 👍👍👍👍👍💯💫💥💯 💥💫💥💯💥💫
1:19 20mm not 20cm
Sir I'm from India I need fibre laser cutting machine
millimeters
you seam to confuse mm and cm
For your enclosure i think you should build it out of welding screen it would be dirt cheap. That way its more protection for your eyes and you can still see through it. With laser glasses too of course
Great project but please stop saying centimetres when it’s millimeters.
ummm.... that was 20mm not 20cm
20milimeter😂
Holy f... Another dude who dont know the Differenzen between centimeter and a mill of a meter ... 1:17
Too much Chinese stuff. It is sad that All these youtubers do based on what was shipped from China. A true DIY is made from locally available products. What a shame.
Man i really dislike aluminum extrusions, even if theyre used widely.
Being a welder, i think id make a steel frame lol. Warping is always an issue, unless your prepared for it properly. Guess aluminum is lighter, and does have those t slots after all.
