wow, it was all about the type of paper!?This looks exactly like the photos in the blog I followed. The gray colour is because there are paper fibers and chalk stuck to the toner.The big question is, how will this etch?

i dont have high hopes for this one but it's a new technique and it needs to be explored

@piggo wait, is *this* off a Brother laser?! old internet lore said it wouldn't work well with those and so I never even bothered trying — that looks nice 🤩

@natevw it's difficult, the printer doesn't want to deposit a thick enough layer of toner, even with +6 density. It also can't properly print on transparencies or the chinese glossy paper. This is semi-glossy magazine paper and I had to use a print pattern like this, with more copies it got smeared. I'm yet to see if it works (the new technique here is acetone-based cold transfer) - I expect over-etching and holes in traces

@piggo ok, yeah that's basically the rationale I found online but seems like it's not a total showstopper, best of luck!

@natevw i have done some boards with it before, with the yellow paper and a laminator. If you have many copies, usually one is almost OK and the rest is fixed with a sharpie. Not good but you get the job done.I'm now also looking into trying UV resist with it, but I have to wait for mr chinaman to send the material

@natevw here's the patterns btw, you can see it's not fully opaque (but still better than with other papers I tried).One trick I used is to layer multiple bad transfers, it's doable but arduous.

@piggo you could open a new YouTube channel; name it “Will it etch?”:blobeyes:

It's bad, but I think I can salvage it with tin coating. The holes are small enough. I really don't want to redo the board after spending all day playing with toner transfer

@piggo Hmm, did you also try with FeCl3? I never tried other things, but I remember some opinions that since it's less aggressive etchant, it is more tolerant to imperfect masks.

@anymouse_404 i didn't and won't, it's disgusting and you get chemical waste from it.There's some other etching salts though

@piggo How does it differ from chemical waste you get from whatever you are using?

@anymouse_404 there's no waste from cucl2. It's self-regenerating, you just leave it in a large bottle and it oxidizes back from black to green.

@piggo Also, disgusting how, it doesn't smell and other than being dangerously brown-staining, it's pretty mild

@anymouse_404 mostly the stains. I can't say anything about smell, my solution also has chlorine in it
