Let's see your lasers

[VA_XTC_Shooter]

Needs some special handling but I'm excited to be able to mark my barrel index jig things

more info on the rotary? is it purchased separately and programmed to match laser?

 

[LVLAaron]

They're pretty "standard" Every machine like this has a rotary port. It's just a servo. You have to configure it in ezcad or lightburn

Better software for laser cutters.

Acquaintance of mine made his own boring head and was looking for a way to finish the dial... Here are some mockups. Ignore my poor sanding and polishing skills.

Aaron,
That is so cool! Thanks for sharing.

Engraved the lower, then cerakoted burnt bronze with milspec OD green over the top. Then back to the laser to burn off the top layer of green.

It looks like the 30w is enough to mark barrels deep enough to cerakote over them and still see the engraving. Would you agree or do you think a guy needs to buy a 50w or 60w?

I am thinking about buying the same one you bought is why I am asking. Thanks.

 

[LVLAaron]

30 Watt is more than enough. You could cut the barrel in half, if you had enough time. Watts = how long it will take.

Also, smaller size lenses really change how fast it "cuts".

Thank you. What lens are you running the 110?

If I'm doing anything flat, yes.

If I'm doing a large logo on a barrel (I have some guys that want 1 inch round logo) - I need the 225 to get enough focal depth to wrap around the barrel

If you're looking for lighter work... Here's a review for a new 20 watt fiber, that's only 1,600 dollars right now.

Looks like a decent option for barrel marking, no? well, except for the software issue.... SO maybe not.

Buddy got a new 22 Creedmoor barrel and asked me if I could laser anything he wanted on the barrel. I reluctantly said yes. My friends, well…they’re my friends

I actually thought he did good:

I did talk him into letting me mark it correctly underneath. We did get a laugh over thinking about someone walking into a store asking for 22 Chingon ammo

Anyone running an exhaust fan system on their laser? If so what are you using?

Fume extractors can be had, but they're expensive. If you can vent out a window, many people just use an inline duct fan of some sort.

I do have access to vent it out a window. Thanks!

I recently bought one of the low end 20W ComMarker fiber lasers. They’ve dropped quite a bit in price (now $1499) so thought I’d try one. This one is not MOPA. I mainly want to mark metals and understood this is supposed to be capable of that.

I made a simple v-block cradle to screw to the relatively small platform, to support the barreled action out past its CG. I marked my first barrel today using the default laser settings of the EZCAD2 that came with the unit. The lower line of text was made with 75 passes (about 5mins)). The upper row (just my initials) was done with 25 passes. I haven’t done any cleaning of the marked area as of yet. Use 2000grit wet/dry maybe?

I’m open to any advice you more experienced laser folks can offer. The unit came with unmarked glasses. I read some people elect to buy certified ones. This laser‘s wavelength is 1064nm. Is there a specific protective set of glasses/goggles that you’ve found to be good?

 

[LVLAaron]

I saw someone review that laser after I bought mine. It looks like it does a fine job, no better than mine. I don't wear the glasses... I also don't stare into the laser.
