I'm having great success with Eagle 9.2.2. I make small boards for through-hole components and, so far have been able to get everything on a single layer without jumpers but next project will require them.

I do an outline on the Milling layer and the router4 cuts out the board.

I have NOT been able to get a 1/4 inch hole recognized and cut however.? It doesn't get picked up by PCB-GCODE and doesn't get cut.? I use the Circle command in Draw to make the hole. I've put it on the milling layer and alternatively on the Dimensions layer, but no-joy.

It possible that I don't have Eagle set up right?

What would you look at if this was your problem?

You may remember a struggle I was having with some traces shorting out.? As it turns out, I had converted a library file for a 28 pin DIP from having little round pads to the elongated type which I find easier to solder.? And of course somehow when I loaded it, Eagle thought it still had the smaller pads and although the traces cleared them, some of them ran right through the pads.

I'm not sure how, but this doesn't seem to happen anymore and I can pretty much etch a board without any manual trace adjustments.

I am puzzled by another effect I'm getting. I like to spot drill pads and set the spot-drill depth to .011, but they get spot-drilled to .075 which is where I have the drill depth set. What am I missing here.

I am after the development of my own economic ATC, so it is also a solution that interests me. With hole diameter and milling data, it is feasible to make larger diameter holes than the tool. I have made a complement for helical descent in BCNC, with help I think it can be implemented directly in Pcbgcode

I John, here I show you what I have done using 3 bits: 0.10 - 0.7 - 3.0 and here I have implemented: I have run pcb gcode 3 times, changing the dimension of the tool to 0.10, 0.8 (0.7 + 0.1) and 3.0.

In BCNC I have enlarged the traces of 0.1 in +0.7. Intersect between traces of 0.7. Then I made a difference with the traces of 0.10. To the result perform pocket operation with 0.10

Between 0.7 and 3.0 the algorithm would have to be repeated (I have done it manually)

Perform a pocket operation on the dimensions of the board for bit 3.0, subtract the traces of 3.0 so that they do not enter it

This is good. I think a good option is to choose one (or more than one) tool diameter to drill, and generate a helical descent of the target radius

Or,
Skip the, 'remove all the copper mentality'!
With completely uncoated boards you only need 50mil spacing for 300V.?
If the board is coated with about anything you need even less - only 16mil.

John & Bruce:

On which layer should I draw my polygon?

Bruce:

If you say I should name my design xxx than you think the file name should be the xxx name?

I'm don't really understand this:

Delete from xxx -

Milling Polygons (except ground plain)

Milling Boundaries

From which xxx should I delete?

From the xxx or xxx-cutout?

Thanks.

You could look into doing a polygon with a crosshatch fill pattern, with the pattern spacing smaller than your endmill size. Been a while, so I’m a bit rusty on the details.

Thank's guys!

One of these solutions will solve my problem.

I think also does engraving a large area of copper with a V carve bit will take too much time.
I will use an endmill?bit 2-3mm.

This situation is not a common?situation so a bit coding in gcode?would be fine I assume.

Thank's all of you.
My best regards.

I thought of that, great if you're having boards made professionally, but if you're using cnc isolation milling it's a very tedious and time-consuming process to remove large areas of copper with a V bit.

One thing you can do is to define the class of the signal as
(arbitrary name) "high power" then define the trace width and minimum
spacing. (then route...)

If PCBGCODE pays attention to that, then you're fine. The traces will
be autorouted far enough away, and if you're hand routing the board,
the DRC check will whine at you.


If not, then just draw the ground plane to exclude the area, or check
how eagle does "keep outs and restricts". That might help.

I’ve had the same problem before, solved it by adding my own gcode at the end of the milling process – used a 2mm carbide end mill to do the milling, removes large areas quickly.

Subject: [pcbgcode] How to etch a powerplane with pcb-gcode? #etch



Hi!

I have to make a pcb where are power traces also beside signal traces.
The power traces are for the main AC/230v which are going into a relay then out on two outputs.

Everything is fine, but! I wish to mill all the copper around the power traces so I can get a copper less clear distance between
the traces so it could not happen does a spark is jumping over the traces.

When we mill our pcb with cnc, we can setup the clearance between the traces, but I don't have to remove the whole
copper from the pcb, just in the area where the power traces are.

I don't know if I explained enough correct but here is a simple picture about my problem:



The N$9, N$10 and N$12 are the power traces.
I wish to remove the copper area what I marked with some green drawings.

Any idea how to achieve this with the pcb-gcode plugin for Eagle?

Thank you.

Hi!

Thanks for the advice,
I'm new in this stuff and I'm relaying to software created/converted gcode sources.
Can you pls send me some example? how you managed the problem?

You don't need to make a complex think just a few steps of code so I can figure out what is doing.

Actually, I like your idea how you solved the problem.

My best regards.
