Unfortunately, the f-theta lens that you get with it is optimized for the near infrared wavelength the laser printers operate at and uses a lot of energy when used with a 405nm laser. So direct mirror might still be the best option (but I have never myself tried the f-theta lenses in these equipments with 405nm, maybe it still is viable enough?) I am currently experimenting with bending mirrors to get a cone mirror ( https://github.com/hzeller/ldgraphy/blob/master/design.md#cone-mirror-arc-e… ), but these experiments were not that successful yet (but this project is only one of many, so things are slower than they could be). I am currently working on a cape for the pocket beagle for LDGraphy. which will be nice and compact and also cheaper as the PocketBeagle is only $25. https://plus.google.com/u/0/+HennerZeller/posts/SnVTjc24AbJ Goal here is to actually make double sided boards with two lasers from two sides. Anyway, I will probably only have more time on this more later this year or January to finish up things. -h > I’m not inclined to work on this alone, but if other people have a > burning > need for something like this, then I would certainly like to > collaborate! > > -Cere > > > > On Sat, Dec 2, 2017 at 11:53 AM, Adam <me(a)adammunich.com> wrote: >> >> Wrong wavelength, resolution. >> >> >> On Dec 2, 2017 11:04 AM, "Cere Davis" <ceremona(a)gmail.com> wrote: >>> >>> I mean cool, but why not just use a laser cutter on low power? >>> >>> ...emailing on the go... >>> @ceremona >>> http://ceredavis.com >>> >>> On Dec 1, 2017 5:23 PM, "Jake" <jake(a)spaz.org> wrote: >>>> >>>> Henner made an open-hardware system for UV curing photoresist, and >>>> it >>>> works: >>>> >>>> https://github.com/hzeller/ldgraphy >>>> >>>> On Fri, 1 Dec 2017, Cere Davis wrote: >>>> >>>>> I mean if it could be UV laser cured with just a laser cutter on >>>>> low >>>>> power >>>>> etch mode, that would be ideal. > > > > > -- > Cere Davis > > Science-Art | Kinetic Sculpture > CereDavis.com > @ceremona
