engraved pcb and holes test 2

IMAG0322.jpg, originally uploaded by Roboteernat.

so here we have some holes and engraved tracks. as you can see i nudged it accidently, however they do line up... have a look at the flickr pic to see the notes.

s i was unsure of theoriginal settings, i didnt have the drill bit down far enough to drill some holes, howeveri manually moved it down whil;st building, therefore not all are there.

tomorrow i recieve my etchant, and also 3 router bits, so i can have a play. My v shapped cutters i ordered from an ebay seller in hong kong - carbide v bits, are due t arrive soon, well a week minimum :( but i hope the drill bits i have (100 (well 90 now as i snapped a few) - good thing i bought 100 for £12.50 (regrinds)) and the routers, i should be able to play and have a good try at making it make. I also want to design some nut holders to fit on the z plate, so that it doesnt play or have the change to nut go into the board when the z plate moves down, as it is currently relying on gravity as apposded to making it drill through the board.

Also i need to secure a scrap piece onto the build base (and possibly make it so that i can screw it onto the y carriage so it is secured firmer, and that i can drill al the way through the pcb without ruining or catching on the magnets in the build base.

then i will make a firmer fixing for the dremil into the z stages, as appsed to my (although working) scrap plastic sheet with 3 holes...

anyways, let me know what you think, as your input is helpful

Well, its been a while as i have not had the internet, but i managed to get it printing, i had a new barrel ordered from and also a new ptfe barrel - i got acetone and sorted it all.

i also bult a small heated builkd base, detials to come, but my new experiment is mamkeing pcb's with the makerbot...

results seem to be great so far, however i am using a snapped 1mm carbide driull bit., not an engraving bit as i shopuld be using.
i have bought some, and they will be with me shortly, however i shall put more pics on short;y. i got v shaped bits, and reouting bits... results are shown below.

i wpould write more, but i havnt had any dinner yet, and im suffering from a small hangover from my birthday outing last night!

this is drilling just around holes - no tracks. the width of the drill bit and the offset angle of the base meant it was not just scraping the tiop but going into the fibreglass below. results showed god, but needs new bits!

second test was with tracks...

this again is a rought output, it is using the broken 1mm drill bit, so its not good outoput - just bought these... so results will be
these aare all 10 degree bits, but i have bought 10, 20, 30 and 60 degree bits, also 4 routing bits... this is how hopefiull i am inn this!
