3 circles close in size as a cut line (no hatch). air blowing on the circle to remove soot. we've cut through 2mm steel in half an hour with a 50 watt with a 50mm circle. The key is air though, you quickly build up a soot layer at the bottom without it and you rapidly get diminishing returns. More air, more better. Also, magnets (I'll let you figure the magnets part out, the other part is a freebie
interestingly. I have a 60W mopa m7 laser and a 6 cm circle in a 1mm steel sheet that burned it for me in about half an hour .. the power consumption was around 235W
Just as others have said. THANK YOU! You just saved me from making a purchase of one tech over another. This video was great because it show what it could do and what it couldn't but in a positive way. I was gifted a D1 PRO 20w, by a friend who bought it but just couldn't get it to do what the ads said. So it sits about 10 feet behind me waiting for my next project. I watch every promotion from laser suppliers and manufacturers trying to absorb everything I can before making the jump into my first laser purchase. Rumor of today is Xtool going to jump into the MOPA laser market. Your willingness to make a vid like this is the reason for my thumbs up and subscribed.
@@flortristanwyes of course it does because the 1kW Fiberlaser is not pulsed it has 1kW CW (continous Wave) 😉 I have a JPT Mopa M7 Fiberlaser with 100W. It Cuts through a 1mm stainless steel in 10min with a 110 x 110mm Lens. Now i bought more Lenses, 50, 70, 150, 175 and 200mm. The reason is if you have the half Spot diameter the power density increases 4 numbers. With the 110mm Lens the spot diameter is 0.04mm and the Power density is 1.2GW/cm2. With the 50mm Lens the power density is round about 6GW/cm2
The wobble settings was made for cutting metal. And you have to set the focus halfway through into your part. Because the beam Focus point gets Smaller and loses power at the focus point the deeper you go.
You're videos are great and very informative. One question, does it significantly shorten the life of the fiber laser to run it at 90-100% power? Thanks!
Thank you very much for your videos, can you please post a video cutting settings of 0.7mm silver on a 50w fiber....I see you use hatch and not wobble, why is that?
hey...so you would have gotten through it faster with a focused fan blowing directly on it to remove the soot. Tested. no fan took 2.5 hours to get through some sheet metal (Forgot the thickness), or 30 minutes with a small desk fan pointing directly on the hole
I was wondering what was the easiest metal to cut /engrave with a fibre. If a 1mm thick engrave was needed ie for a leather stamp or possibly branding iron what would be the best metal to use?
As one other comment said, the focus is only optimal for a very limited z height. At some point it will simply stop cutting. Try to move the laser down in some increment - maybe 0.3mm, since that is what was advertised....
Yep that's what I thought too and I tried to play with focus during this experiment but it didn't have a major impact. Since making this video, I've learned about the wobble setting which helps achieve depth for something like this. Really, a 20w just isn't a good tool for this kind of depth.
What lens was this done with? I have a 50W on order with the 70mm x 70mm lens. I've heard with the small working area it gives even more power to the spot but can actually be worse for cutting because of the focal length? Any details on that?
Hi, your videos you have made on the Chinese laser have helped me decide to buy one, currently on its and expect in late January. One question you might be able to answer for me! I I would like to cut gold and silver 0.15mm thick , I have ordered a 20w fiber laser with a 110x110 lens do you think it will cut ok or will I need a 70x70 lens / more power? Thanks in advance..and a happy Xmas to you, regards Ed👍
This is very helpful! Is it possible to upload the programs that you are using? So we can test them correctlly. I have access to a 50 Watt machine and I am trying to make some tests
Im planing to get a 20W fiber laser as well. a 40x40mm lens on it. i wonder if i could cut through 1mm efficiently . what are your thoughts? The energy density of the laser would increase compared to 110x110 setup
Hello Jeffery, I tried to deep engrave a 1mm stainless steel plate (50mm text height) but the plate is bend from the heat of the laser. Is there anything I can do to make it not bend? or should I harden the plate first?
It will do 3 thou, but if you're going for depth in production quantity or over a large area, I would probably get a 30 or 50W laser as it will be a lot faster.
@@MrKillerdead Could you please tell me what kind of parameters (offset, hatch, different pens, simply whatever parameters you find useful in this process) do you use to cut through 2mm stainless steel ?

My 1kW fiber laser cutter takes about a second to cut that. I'm just ordered a 50W engraver though and I find your videos very helpful :-)
Glad to help!
I have a 50w laser. Did you use these same settings to cut?
1kW? Dang …does that make it 20x more powerful than a 50W?
@@flortristanwyes of course it does because the 1kW Fiberlaser is not pulsed it has 1kW CW (continous Wave) 😉

if you use air to blast the particles away it will cut much deeper
This is where you would use your wobble settings
@JefferyJ try using the wobble setting in advance... by the Audi logo (freq)... game-changer when cutting
Thanks, I'll give it a try!
The wobble settings was made for cutting metal. And you have to set the focus halfway through into your part. Because the beam Focus point gets Smaller and loses power at the focus point the deeper you go.
I heard wobble option is bad for your laser?
@@EJSVARZ Absolutely wrong.
how about 1mm silver or gold? i think those 2 are softer than steel.
I'm learning how to use a fiber laser. Why not use the wobble setting?
Thank you! This was very helpful!

Yes

Hey Jeffery, what size laser do you reckon a person would need to do this in under 30 secs?
This is where wobble settings are useful. Also a telecentric lens.
I was wondering what was the easiest metal to cut /engrave with a fibre. If a 1mm thick engrave was needed ie for a leather stamp or possibly branding iron what would be the best metal to use?
Hi, it possible deep engraving (cutting), with 50w raycus fiber laser to 1.2mm stainless steel sheet?
As one other comment said, the focus is only optimal for a very limited z height. At some point it will simply stop cutting. Try to move the laser down in some increment - maybe 0.3mm, since that is what was advertised....

I'm new here. I just got a 60w Fiber laser. I want to engrave and cut out image on 1mm metal. How can i outline the image to cut.
Use the 'offset' function in ezcad in the 'edit' menu.
what function of frequency and start TC ?
What lens was this done with? I have a 50W on order with the 70mm x 70mm lens. I've heard with the small working area it gives even more power to the spot but can actually be worse for cutting because of the focal length? Any details on that?
Hey jeff, using 30w what setting do I use to cut through 1.5mm stainless and how long do you think it will take?
thank you

I don't do much (or any really) cutting so I'd only be guessing. I'd start with your 110 and go from there. Lenses aren't a big deal to order later.
This is very helpful!

Not much of a "program" - It's exactly what you see on the screen.
You an try a 50*50 lens! :)
how much time took to cut one round sheet
Im planing to get a 20W fiber laser as well. a 40x40mm lens on it. i wonder if i could cut through 1mm efficiently . what are your thoughts? The energy density of the laser would increase compared to 110x110 setup
@zomgthisisawesomelol Engraving Dials and watch parts :)
@zomgthisisawesomelol good news! i shall get my laser delivered in about 2 weeks. with a 50x50mm lens installed. i can then record my tests :)
So.. have u tried with 0.3mm?
I'm thinking about the 30W for cutting 0.3mm - 0.5mm.. not sure yet
I haven't, but you should be able to get through that.

You could try to cool it while you're marking.
@@jefferyj Wise choice.
@@jefferyj which settings of wobble did you use
What settings do you use ?
He states the setting in the video.
Google thank you for spying on me 😃 now can you tell me please with what to color the engraved metal and leather?
Any plans on getting the rotary attachment?
I've thought about it, but it would be just for fun as I can't really justify it any other way. I think they run $400 or so...I'm undecided.
@@jefferyj The rotary we only charge 102USD EXW. :)
I need an engraver that will engrave to a depth of .003” in gun metal steel. Do you recommend this device.
It will do 3 thou, but if you're going for depth in production quantity or over a large area, I would probably get a 30 or 50W laser as it will be a lot faster.
... What model is your laser ?.
It's a raycus 20w. Check out the first video I ever made for more details.
What about 1mm aluminum?
Unfortunately, no. Thin stuff will cut, but about the max thickness with multiple passes is 0.3mm.
@@jefferyj yes 20w fiber can, i cut 2mm stainless steel with high dopped carboneum, 20х25mm cutting little bit 1 hour, clear alum more faster
@@MrKillerdead Could you please tell me what kind of parameters (offset, hatch, different pens, simply whatever parameters you find useful in this process) do you use to cut through 2mm stainless steel ?
Daniil Gorid-Lanier yes I’d love to see a post of the setting. Plz do!!!
Cut 1mm of metal in under a minute with our 50 watt laser machine
Seriously ? What are you using?
Is this capable of cutting a hairline?
Not the right technik and settings
can you share right settings and techniq?
