Archive of the former Yahoo!Groups mailing list: Homebrew PCBs

...

I personally do not care at all in which list the stuff is discussed,
as long as i am a member ;-).


I don't think that anyone tries to weaken the pcb list at all, it was more
an attempt to keep the list free of too OT things (and yes it can go OT
with cnc.).

I also agree the other popular cnc list (edm cnc i think) is very
intimidating, and
honestly i do not like it very much.

I don't think it is a bad idea to have the cnc list, but i also think it
was not OT here.

Damn i get a 50 or so spam mails a day, i do not care if i have to ignore
20 posts on a list
which have a topic that i find not interesting, and know nothing about.
That's what the subject line is for (SO PLEASE ALWAYS CHNANGE IT).

I strongly suggest to leave the decision about what it OT to the list
owner/moderator
(who does a magnificent job if i might say so).
I also suggest that if someone mentions there might be another list which
is even
closer to the topic that it is taken as what it was meant for, an attempt
to help.



I still have not worked out the cnc paste despensing stuff and i suggest
the discussion
going back there, or somewhere else. After all the CURRENT topic is
clearly OFF TOPIC.


I still do not understand where and how those macros, or whatever they are
called is inserted.
I mean i have a drawing of my solder paste layer, nothing more.
It contains short lines where the paste must go, that's it.
This file does know nothing about how deep the dispenser has to be
lowered, or anything.
It is like a plotter file, just 2 dimensional.
I have zero CNC knoweledge (ok that is not exactly true) and i don't know
how i come
from a 2D gerber file to the signals on the pc port that control the
motors.

Would be really, really helpful if someone could (maybe again) explain how
this is done.
Please assume a two-and-a-half D Milling project for explanation, as it
seems the same to me.
Assume one has a 2D gerber line-art and wants to mill it. how does he
process the 2D file
to get the machine to move.



Thanks a lot.
