Is There Engraving Machine Anonymous?

@Golem Pens

Crappy but possible. This is a 5.5w diode laser. Need to fiddle around with speed and intensity to get that nice sharp deep engraving, and the wood dowel is much lighter than ebonite, so will not cut as evenly. The rough edges are a function of the wood grain, if you compare to the same engraving done on PVC you can see the laser moves nice and straight, it's just the woodgrain that mucks up the engraving edges, and I haven't dialled in intensity and speed for PVC. Ebonite probably won't bleed as much, if at all.

And I can't spell...

I wouldn't be laser engraving PVC! You may or may not already know but if not, engraving PVC is dangerous to both you and your machine. Hydrogen chloride, vinyl chloride and chlorine gas are just a few toxic gasses released during the process and not only dangerous to you but will corrode your machine in short order.

I'm wrong, should have looked it up before I posted. It's not PVC, it's ABS double color sheet,


I believe this is OK for laser work?

Well, it releases toxic fumes as well but at least it won't hurt your laser. If you have an exhaust system on your laser then ya go for it but I'd think twice about it indoors without an exterior extractor. I made a complete enclosure for my fiber laser with a strong extractor which works well.
 
if anyone else is looking for the dot peener ..... Amazon was messed. Vendor advertising on .ca so obviously expects to sell to Canada, contacts me right away and says their courier won't go to my address. wtf? then item is listed at a high price. Waste of time.... imo Amazon should try to clean up that crap as it damages their brand.

This would have been a great one to go to Vevor for, turns out its the only product under the sun they don't sell.

Ebay wth all the fees was 850 or so, aliexpres, high shipping. Went with alibaba - 462 US$ shipped. cheapest of all they've a good rep for buyer protection. We'll see 🙂

Which Hermes? I have the dragger that is kinda of neat and also the rotating spindle one. Yours look like spindle work vs the diamond dragger..... but since you say it's diamond maybe not? The spindle one I thought was primarily for use with the two colour plastic sheets like Gravoply or whatever .... never really use it and am wondering if its useful beyond plastic

ITX machine with regular bits, not carbide. Most of my d-bits are drastically in need of sharpening. I also have a Dalhgren 300 that's much more robust but not as much fun to use.

Samples on a chunk of aluminum scrap, results are iffy because I didn't spend any time making sure everything was flat and clean, and I just rushed through the process. If I'm doing something important there won't be as many divots.

Diamond drag bit
0.020" d-bit @ 8000 RPM
0.040' rotary diamond bit

The rotary bit leaves a rough bottom to the groove, but once it's filled in with paint results are acceptable, as shown on my CNC Controller front panel.

Diamond rotary works great on aluminum but only a fixed point diameter so can't scale to match the letter size, unlike the d-bits.

You know, this clueless n00b was having the hardest time parsing the subject line of this thread (you know, there are so many brand names I'm not familiar with (yet), etc.). But I finally got it, so I think my mind is beginning to sync with the general trend of things around here.
 
Don’t worry, when you start getting the hang of a post, it will take a swing at something else. Now if we can computerize the post with some programming and then get Linux involved, (who ever he is) or one of them others and start abreveate —ing some of the stuff, things get more interesting and brain freezing, LOL, LOL.

Sorry - being new here I don't know where you are. I'm rural, and three hours from the border. So I have a wide array of addresses: My Canada Post PO box, the street address, a Montana USPS box, and a freight warehouse just down the street from it. That gives me a lot of possibilities for: a) choosing an address that the seller will ship to, and b) minimizing shipping cost. Ridiculously, often amazon will ship to either my street address or my PO box, but not both (i.e. XOR). If speed is an issue, obviously I have to consider eating a shipping premium to get it here directly, but in most cases it can wait down in the US until enough accumulates for me to justify the day trip down to fetch it (which is almost the case now), or for the old friend with whom I share the box - and who lives between Milk River and the border - to come up to Lethbridge or Calgary for other stuff. (And yes, that's the Coutts border crossing where the "Freedom!" knuckleheads made a fuss a few years back - he watched that circus from his front yard.)

Incidentally, I hadn't heard from him for a couple of weeks - turns out that on Tuesday he was the passenger in his wife's new Subaru Crosstrek in Lethbridge when his side was T-boned by some big-ass farm truck that blew a light. Took firemen 45 minutes to cut him out of it. Banged up and sore as hell, but nothing broken, pretty impressive for an 80+ year old - who credits side air bags with saving his life.

Oh - and as for Bezos giving a toss about damage to amazon's brand? Honestly? And don't get me started on how bad a look being white, completely bald, and without any facial hair is. Black guys can pull that off, but whitey, grow a beard, okay?

(Now how's that for subject drift?)
