Title: Laser engravers
Post by: Shaggy45 on October 03, 2018, 06:54:27 PM
Could one of you fine folks point me in the direction of a laser engraver that will get through powder coating cleanly?  Is this a possibility with out spending thousands? Or would I be better off with a desktop cnc?

Tried to use the search function but it was down.

Thanks

Just to get you started on the topic. I've bought the Elekslaser A3 with 2.something W and it's not enough to go through a Tayda powder coat in one go at full power. you could use slower feed, but the detail you can achieve really suffers... I'm not sure if there's an affordable solution for DIYers for this.

Unfortunately, we had to spend a boatload of money to get a good one.  Iíve not come across a DIY one that was great, although I believe Culturejam finally got his setup to the point that it mostly worked.

Thanks for the links, Iíll check them out.

Which laser did yíall end up with pickdropper? Just in case I fall into a large sum of money one day.

An Epilog Mini 1812.  Itís basically an entry level production laser.  I think MSRP is $15k, but you can get them in the $10-12k range if you get them when thereís a trade show special.  I would never be able to justify one for DIY builds; they are just too expensive.

If you get an engraver and you are planning on cutting anything with it, make sure you setup proper ventilation.  The fumes can be nasty and some materials (such as acrylic) will burst into open flame if there isnít a vent fan pulling air across the cut.

Check out the Emblaser from Darkly Labs.

The Emblaser 1 comes as a DIY kit.. It's pretty expensive compared to a chinese laser, but the support, community and software is worth the extra imo.
I had the Emblaser 1 (still have unused it in a box actually... anyone wants it? :P) but upgraded to Emblaser Two which is improved in every way.

Asgeir who ran Pedal Projects used a Emblaser 1 to engrave his pedals. It's very slow... but the results can be nice.
He powder coated the pedals himself in different layers to make different color combinations.

Jimmie who runs Reaper Pedals also used an Emblaser 1, but he made faceplates like me.

That looks pretty good.  Iíll gave to check that out.

Thanks Freppo, that looks sweet. Still pretty expensive for the v2  :o

Is there a specific wattage i should be looking for to know that the laser will do the job?

Perhaps cnc would be a cheaper option. Is it correct to understand that cnc won't be as detailed as a laser engraver? at least with the size of pedals?

Yeah, the V2 is expensive, but I got it for a 50% pre-order deal. :)

However.. I was very tempted to get an EleksMaker laser from Banggood, since they are very cheap.
They actually look very sturdy and a much better build than the Emblaser 1, which is mostly made out of cut acrylic and 3D printed parts.
With some mods, I think they can be a very good option. https://www.youtube.com/watch?v=ZzO9skEYqwY (https://www.youtube.com/watch?v=ZzO9skEYqwY)

I think that might be the model that Culturejam and Madbean have.

I'm curious too.  FYI: if you live near Anaheim, these are available on CL for $100, same seller presumably.

I actually saw a 10W diode laser in a partially assembled kit and it's about $400. I don't want the hassle of water cooling a CO2 laser and the other accessory needs (ventilation to outside, etc). So I like the diode lasers, even though they are usually under powered for all but minimal powdercoat etching. But 10W ought to be able to do a lot more than the <3W diode lasers I've been mucking around with.

I just worked out a new process last night/today that seems to work adequately well, assuming you are okay with not actually cutting all the way down to the metal. I'm going to be posting notes in another thread with all the details, but here's my first test box (below). I need to adjust the artwork a bit to allow for the laser bleed, but the process works.

That looks good culturejam.

Lasers already seem like you have to fiddle with them a lot. In the end I at least want a good amount of power. Iím on a bad shift right now to do research ,so that will have to wait. At this point I know absolutely nothing about them. If I do end up getting one I will share my experience in this thread. And if anyone else has some info please feel free  :D

Hi,

That looks pretty cool!
How do you align the pedal under the laser. Is there a 0,0 coordinate?

Thanks
