I went to LPKF school - it was instructive - a little obtuse due to the
software being a little that way.

We used mostly 7 and 10 mil 2 flute endmill and some stronger drill like tools
that were used to cut out slots and holes.

The pcb was mounted atop a special type of Masonite like board - flat on both
sides and dust free - more or less. Use a vac of some type - the fine fiber
can be harmful.

The board under the one we were drilling is there to protect drilling through
into the metal bed.

If you are in the Bay area - or a PCB area - go to a grinding shop.
You will find boxes of un-claimed drills and mills and other shaped cutters.



Unfortunately no. I live out in the sticks(relatively speaking).
There may be some companies around here that do this type of thing
though. I will have to do some calling and see what I can find out.

Sounds like these may be useful, but neccesarily everything I need.
Drilling PCBs is part of the goal, but still need a cutter for traces
and other modelling.


Do you have any documentation - ? Hope so - it helps.


Yes and no. I can't find a manual for my exact machine, but I have
found stuff for newer machines that is "close enough" to at least get
me somewhere. W/O that I probably would still be swearing at it.

FWIW - It is a CAMM3 PNC-3000 made by Roland. Mfg in the mid-80s.

Thanks
