Chinese Laser engraver for marking and engraving

[Corn]

Dear All,

I’m tempted in buying 50W fiber laser engraving machine and would like to hear some thoughts about them. I’ve particularly interested on Chinese table top, non closure with JPT LP E-50W laser emitter and around $5000 price range. I’ve watched few review videos from YT and they seem to get mostly positive feedback. Are these generally how long lasting devices? Also I’m concerned about the safety and have few doubts. I’m not sure is it even allowed to sell any non enclosed laser engravers/markers in EU. With the enclosure it would be easier to extract the fumes. How bad are the fumes when engraving AL, ST/ST or some plastics which can be engraved by fiber laser or is it the same than welding them? PVC at least is big no no. Is it enough to vent the fumes through HEPA filter or must vent them outside? For eyes, is it enough to wear the laser safety goggles?

JPT seem to have frequency range from 1-600kHz. Others ~20-60kHz. Does wider frequency range allow more material variety?

Thank you in advance

I have a 50w jpt open machine w/rotory .
Used for aluminums. Steels and stainless steels.
Also cut cardboard with it. Not supposed to work but it does.

50w is nice for deep engraving. Or for large work areal 10x10”
Otherwise save some bucks and go 20-30. Most people do not need 50w

Chinese lasers are cheap and easy to buy. Software is so so. And expect little to no customer support or warranty. YouTube laser master academy. Alex is a big help over there.

If you got time to F around. Chinese is not a bad route.
If you want any support at all your gonna need a much more $$$ vendor. But the major brands will have your back,

Ventilation is a must your vaporizing or ablading materials into a micro fine dust.
Hepa should be fine. I vent it outside after a filter just to be safe.
As an example the dust from ablading aluminum is as fine as talcum powder.
Vision. They say the shields or glasses are fine. Personally if I have a lot of engraving to do I toss a physical barrier in the way.

Frequency’s. It depends on what you wanna do. 20-80k variations are perfect for metals/engraving.
The jpt 2-600 will open up engraving some plastics. 400-600 let me cut cardboard. 300-400/defocus did a nice aneel on stainless.

Overall very happy. Quality of engraving is great. Speed is great.
Setup/learning curve sucked.
Got maybe 300hours laser on time. No problems at all.
Great for blasting my logo all over everything.

Light burn for galvo is out of beta now?
I’ll have to look into it,
Anything particularly better?
That burn looks fantastic, how deep is it? Mind sharing your settings?

That was .07 deep about 8 hours burn time run on max than 45 percent 45 freq and 1000 mm-s to clean the floors up. Then surface grind the top about .002. They are for a hot stamp die for oil filler caps

How do you get lightburn to talk to the machine?

I bought a 100w Chinese fiber laser a few years ago before the huge price hikes and have used it for some markings and logo engraving, but its painful to learn. Haven't had much time to play with it but would love something easier to program it with.

Look up “laser everything” on YouTube. Fella names Alex is putting out great content for these fiber lasers
How much was your 100W
I got my 50 2 years ago I thing? Was 5500cdn with the rotory incl. if I remember correct

100 would be sick!

I paid the same $5500 all in with 2 lenses, a rotary and shipping/taxes Canadian for the 100W I think maybe 3.5 years ago or so, before Covid messed things up. Bought it off Alibaba. Its a JW JingWei Laser. Looks like all the other Silver and blue anodized machines

Looking back.
I paid 4300 in March 2021. That includes shipping
50w jpt Laser was 3620 before shipping

Man a 100w for 5500 woulda been sweet. Looking around $9000 now

Well I just bought a JPT 50 watt 300mmx300mm engraver for $2500 on AliExpress (I prefer express over baba whenever possible due to seller being responsible for shipping on express). Hopefully it works well. I'll know in a month.
