Re: [CAD_CAM_EDM_DRO] Re: Eagle drill-files (was: faster steppers)

Alan,

> Stepster understands .DRD (Excellon?) files?

No, not direct. You have to edit the .drd the way I wrote in my last
message. That is adding the G81 command. Then you have to setup Stepster (or
whatever program you like, KellyCAM, EMC, etc etc)so it reads the file in
mils and not in inches (or mm in my case) OR you could convert the .drd file
so that the X&Y cordinates reads in inches.

This is the beginning of a .drd file that I ran i Stepster yesterday, works
perfect.
The only thing I do is add the G81 with its Z, R & F commands.

G81 X385 Y488 Z-130 R30 F75

X385Y588
X385Y688

X185Y688
X185Y788

As you can see, the X&Y cordinates are not in inches thats why you have to
edit either the the .drd file itself or the movement-per-step-setting in
your controler.
I don't know about EMC but atleast in Stepster you dont need any
linenumbers. It's pretty easy to generate the .drd file and make the changes
and it goes a heck of a lot faster to drill it with CNC than to do it by
hand. I haven't tried to get the data out to mill the traces. It would be
nice to be able to do it, but I don't think my machine is up to it (I need
to build a floating engraving head) so I stick with etching and just do the
drilling with CNC.

I'm not even near knowing all the functions in Eagle but I know some. So if
you have any questions I'll be glad to help, if I can.
