I wonder if Russ at the New Yorkshire Workshop channel could be persuaded to have a go at cutting some stainless SMD stencils too. His cutter is much more conventional, but a pretty meaty affair, and it would be interesting to see what the spot size is.

I do copper PCB with a JPT 20W MOPA and it works just fine without burning the board. You do want to have the laser moving over the surface and not spending its time in one small spot all the time.

I’ve also been diving into the PCB laser space, but using a cheap 5W diode laser. In my case I’m using Lightburn’s offset fill to get good edges on my outlines, which seems to work quite well. At least, after I run the KiCAD SVG output through an extensive shell script to invert and flip it if necessary, flatten all the beziers, collapse the layers, and do laser beam width compensation while I’m at it. I use a black spray-lacquer as my etch resist, because it burns off easily but is easy to clean off with IPA. What I’m running into problems with now is the solder mask. I tried painting a full layer of (acetone thinned) UV-cure solder-mask to the board, curing it in the sun, and ablating the parts that I didn’t want, but the solder mask was proving difficult to burn away when over copper, and too easy to burn through when atop fibreglass, causing charring. Also it smells like 5 flavours of cancer. My next tests will involve using high-temperature spray paint as a solder mask, where hopefully the thinner layer will make it easier to burn though. Otherwise I can invert the mask layers and try using the blue laser to preferentially cure areas of the solder mask. Double sided alignment and automatic drilling have yet to be tackled, though both should be reasonably straightforward. My machine is just a modified Ender 3. FYI for those with resin printers, UVtools has a UV PCB exposure method that works decently. I found the contrast wasn’t good enough for my sub-par dry film photoresist, but I bet with a double LCD or a DLP it would definitely be good enough.

I have a similar setup, in my case it's a cheap 500mW purple laser module that i attached to my Ender 3, also using black spray paint. I am using FlatCAM to process gerber files from KiCAD, works pretty well. Layer alignment is a bit tricky, i printed out an end stop that allows me to fine tune the angle of the board so that it sits perpendicular to both axes. I measure the exact dimension of the board and offset the layers so that they sit on top of each other once i flipped the board around. Solder mask is something i've kinda given up on though.

Yes, the topic of boobs is not disclosed😐. As I thought so far, for prototyping it is better than an engraver like Bungard will not work. Etching is also, of course, good and fast enough, but this does not solve the problem with drilling. As for the solder mask, it is easier to remove it again with an engraver. The question is about prototyping, because if I need a lot of the same type of boards, I will order them in China.

@@DevilAgent ah yeah, the other option for solder mask is to use one of those spring-loaded engraving tips. They have low enough cutting forces that it’s probably fine to use on an Ender 3. Though without a dual-Z mod I’ll want to be a bit conservative with downward pressure. The other big bonus you get from Chinese boards is plated through-holes. There are homemade alternatives like electroless silver plating (fibre laser palladium nanoparticles being another), but they all look like a real pain. My thinking is to stick to China fab houses for complicated breakout boards and finished projects, while diy PCBs should be used to stick these breakout boards together in simple ways, and for making sufficiently simple boards.
