Now I use dremel but I leave the brushless option behind because now I made my pcb's using the spray paint and laser technique, its very accurate with a 0.2mm laser dot, It uses a 2w 445nm laser on a cnc to burn the black paint of the pcb surface and then etch with the sponge etching metodth.
"Be Anal" I believe that you're talking something like analogic right?, but if you do speed reading and appears "Be anal" that make me laugh :P
Judging for the pictures of the cad model, I believed you used SW right? Awesome Build I loved it :D
Step 6 LOL
This is very a PRO design , great job :D
Turn Drawings into Laser Cut Fabric
Very clever the way you made the solder mask, I didn't know comex sell acid, Maybe you should try to make this instructables in both languages, A hole new way to make pcb´s, I like it.
Hi Hawk you need at least 2w but real watts not chinese watts I know thats sounds weird but the chinese or the cheap "very cheap" laser modules are less power than rated, with 2w and just 1 pass at 180mm/min to 200mm/min "Feedrate" you can burn black mate coat on a PCB surface and works very great. I´m making an instructable of that process here's an advance
I meant WITH but I don't know why I can't edit the comment :P
Whit a laser CO2 Up to 4mm using 40w for 5mm to 10mm thicknes you need like 60w-80w, 10mm-20mm can be made with 80w-120w Co2 laser tube, and of course with cnc any dremel can cut up to 5mm-6mm, a router like 6A to 15A with a good cutter bit can cut 20mm.
Hi jlcdi , if your plastic sheets are transparent or white you can no cut either with visible lasers. You need to use a setup or build a machine with a Co2 laser instead, you can cut black or dark plastics with 4w-6w using visible lasers but is only recomended to cut 3-4mm thick. These 5-6w lasers must be a good quality laser not cheap chinese laser because they are annunced as 5w but they can only pull 2.5w-3w.
You need to use YAG laser to engrave metal :), even a Co2 laser need at least 300w-400w to make a scrath on metal surfaces.
Or use 60w-100w CO2 to engrave with special coats to make an engrave on metal surfaces but they are no everlasting like YAG engraves, an engrave made with yag laser are for lifetime.
This instructable is great to all who wants this duality on his 3D printer. And for those who wants to buy a laser buy a 2w or powerfull laser, try to buy the diode in ebay from DTR's shop (US), is way cheaper and better quality compared to the chinese all in one modules. With a 2w laser the things get usefull an you can get profit with that. I hope the author don't get mad with me to posting a link to my instructable here but may help to some one. one: http://www.instructables.com/id/Heatsink-for-Diy-Laser-Engraver/

Wow I love it , really awesome :)
Maggot Infested Skin (Trypophobia) Doctor Costume
You guys don't peel the tomatoes, leave that burned skin of the tomatoes, that's the main and the original special taste of this type of salsa. I'm from Mexico and this recipe is almost authentic :p , try this salsa with the burned skin of the tomatoes and taste the difference. I really love this salsa is easy to make.

Yeah, is better to have 2 options available of laser , visible lasers are good for engraving and 8-bit shade of gray photo engrave and Co2 are better for cutting any material (almost). I don't like to cut with visible laser either engrave wood with co2, because I think is better to engrave with a diode to reduce the cost per minute of the diode and don´t waste the hours of life of the co2 laser. Both are good and I use blue laser to engrave and Co2 to cut, if you keep this way to implement laser machines in your project or business, you can save money, co2 tubes are expensive :(.
Saul and Blanche both are complete right, to wear inapropiate cloths and gloves becomes very dangerous things to wear when working with drills, milling, lathe, they are very powerful and dangerous machines, I indeed used a vise to make all the holes, like the picture from the step 9. And yes blanchae, I used like 12 or 15 diferent drill bits to get to the desired size, to mantain the original center and to avoid unexpected results like a hole bigger than the drill bit, that happens when you swap from a little drill bit to a bigger. So the photo with the gloves shows the last drill bit drilling and cleaning the chips, the gloves are for protect from the heat because the piece was very hot, but I think I should write: do not attempt to hold the piece by hand :)
Yeah they are very useful machines or toys, don't be offended, I often call them toys because I love to play with those machines and I don't feel like I'm working
Sergey I was tried to talk about to build a machine, to buy a Co2 laser cnc is way too expensive, very expensive, but build one is not so expensive, check the Lasersaur project to get an idea. I'm building one and it's cost me like $1.3k-$1.5k usd it's a real deal.
Yeah K40's cutter sucks LOL, It's better make your own machine, you can change the control hardware and use an appropiate software CAM, there is a lot of improvements that can be made on that machine.The 445nm laser type are better for wood and more cheaper. If you already have a K40 you can attach a laser diode like showed in this instructable and control with arduino grbl or ramps with 3d printer firmware and you will have 2 laser machines :).The chinese machines are very low cost, so is normal to they come with very low quality parts.

Thanks Simon, I hope you liked. This project took me like 3 hrs to make but like 1 week to keep it short and easy to follow.
According to the Grbl version could be in pin 12 , make sure to read the grbl wiki to know more about the pwm spindle control and the non pwm firmware
Thanks Sanjaykray, I'm preparing another to explain the cam process for diy laser cnc.

How to calibrate the Extruder on your 3d Printer
There is no virus, is because a chinese software always will be like a tread for any browser, antivirus, it seems to work with an arduino clone and grbl 8 because interfacing with serial speed of 115200 b/s gets error and the program crashes, I'm pretty sure it will work with 9600 b/s
The software is free? I'm using: Inksacpe with a plugin works well but I need something better or with more options to engrave, I made my own machine with 445nm laser (blue laser) ,The hex key you mentioned is to have access to the software?
