CNC etching is just as OT as laser printer toner transfer and
printer/toner/inkjet/film discussions. Printers are CNC machines
too.

The similar interests are to achieve the ∗end∗ result. I'd rather
see CNC discussions here than boring old laser printer crap which
i know is inconsistant between models and toner brands anyway. However,
i don't bitch about it OT.

PCB making crosses as many fields as you want. The list members come
from many fields. A mech.eng that wants to make PCBs might find
chemical etching OT just as much as i find laser printers OT.

But i know ∗everything∗ electronic and have been learning more
things mechanical.

That's too restrictive. Discussions on lightbox design is just
as relevant.

Everything. PCBs are ∗mechanical∗.
