thats funny....
exactly this page i read some hours ago and thought it might be worth
posting it here.
but then i forgot...
this is also the reason why i asked for xaar heads.
they write it is in the Xerox Xpress which is a large format printer i
think.
so i wondered if there are also other printers with ths head (xerox or
others.).
the 300dpi is not too much, but the advantage would be that higher
resolution heads may clog more easily.
something in the hp head caused it not to work.
i think it is a bad idea at all to try this with a thermal inkjet.
but i didn't spend too much for this project and if i can get myself to
reassemble the second printer
i tried (after killing the hp550c) i will also still have one inkjet if i
ever need.
i had a quick look at ebay and there are still lots of inkjets.
but i don't want to buy some epson model if i can get maybe a better one
(maybe xaar head).
i also really like the plotting method. this closed drill holes in the pads
i still hate but i think
i can live with it (if i have a good drill press it will work also with no
center - punch).
no there is not much incentive to try the inkjet printing again (i will
leave that for you guys out there and then
buy exactly the right printer which you have figured out).
i look forward to reading of the first positive results.
by the way, there is a proxxon circular saw at ebay, the guy sayd 3 blades
included. i asked which blades.
he sayd one of them carbide (full material).
it auction is at 30eur now.
if it doesn't get much above 60eur i will buy it. so no further ambitions
to build my own one.
regards
stefan
