sounds like the old shampoo ad. Cut, repeat.

While I'm at it i want to again thank you for your wonderful code.? As I wrote when I first surfaced the swarf problem, I've gotten my design and cut routine down cold - everything works.

best regards,

Yes, that’s the idea. I got tired of cleaning the grooves myself.

HI Dan,

I've been cutting my "grooves" in a single pass. I'm assuming
"steps" means offsets, maybe cutting a groove and then making
another pass .001 nearer the trace to clean it up. Is that it?

I had the idea of repeating the cuts assuming that the next pass
would throw the swarf out of the groove.

If I want to do steps, I assume I would need to increase trace
separation in Eagle and then set the step in pcbgcode.? If this is
approximately right, I'll go back to the manual and try it.

my boards, except for one, are single sided with no vias. they
have a number pf dip sockets and traces must pass between pins and
there isn't a lot of space there - .010 pin separation and I like
to use the long pads; tight.

what do you think?

What step size do you use and what cutter diameter?
I’ve found if I use a step of >=50% the cutter foam, I get
these “leftovers”, but, if I set a step of 30-40%, it tends to
be clean. Takes longer, of course.
