An arduino uno and for the controlling I use  processing program

Which "processing program"??

Need to know what it wants to be fed.

This one  https://processing.org/download/
For Windows 64bit
And I send  Gcode files(with .Gcode extension from Inkspace, I was exporting my pcb layout as an image and converting it in Inkspace to gcode) but i heard that eagle can make gcode for plotters and couldnt find its way

I'm using the autoleveler for Grbl control units built into Chilipeppr with wonderful results.  The second etching (the etching on top) was when I tried to reduce the size of the min/max and step size.  I didn't alter the drill size, so I thought, it would allow it to cut between the pads properly without reducing the milling of the traces.

 

The traces is what I'm having trouble preserving.  I really don't understand why, if I don't change the drill bit size, it get's into the traces.

That looks beautiful.  What settings are you using for your min/max and step size?  Also, when you use a 30 degree V bit, what size do you enter for your drill bit size.  Also, what unit size are you using (inches, mm, or mils)?

Many thanks for the help, Y?es the problem was the interface from my chair to the PC.

After resetting the zero all worked on.

Again thanks for putting u[p with my incompetence.

OK, have been away from the house most of the afternoon, but will look into it this evening and get back to you.

I spent a while looking at the site you linked to and have come to the conclusion that it is a programing language system.

Pcb-gcode is designed only to output gcode and as such is not compatible with your system. I do not know how to covert gcode to your input requirements either.

Sorry for the bad news.

You will need a controller like Mach3/4, Linuxcnc, Turbocnc, Grbl, etc.
The first three are computer based, and Grbl is Ardinuo based.

There is an extension for controlling https://www.google.com.tr/amp/www.instructables.com/id/CNC-Gcode-Sender/%3famp_page=true  
Arent they for the milling cnc machine, but i have a plotter.
And what do you mean by arduino based? Should i setup it on arduino or i should make some changes with arduino programming

Looks like you have found a way to "plot" using gcode with your existing system. As stated before, I am not familiar with this so any advice I might have wouldn't be worth the electrons to send it.

From a quick glance, it should be able to do what you want, but I am not the person that has the knowledge to help you.

My comment regarding using an Ardunio, was based on other things that I have seen. But then again, I am not familiar with their workings either.

I think what they mean by, 'arduino based', is that, like most diy machines used for milling, the code is sent to the arduino, from a PC/Laptop,, which then drives the 3 stepper motors and milling motor.

More professional machines have a purpose built board and so is not arduimo based.

They need to know if you have an arduino driver board or if not what type you do have.

Hope thiws helps a little

Thanks 
I'm using arduino nano to control the plotter 

Re: mill layer #mill

Hi, I too am having problems with text.

I have set the text to Vector, the other two options I have are, 'proportional' and 'fixed'.

I attach a screen-print of the properties I have chosen. Here the pour can be 'solid', 'hatch', or 'cut out'. Not sure which to choose here.

I do get an outline of the text box but nothing is filling inside.

Many thanks in advance for any help you can offer, I am using eagle 7.7 on win 10 with an arduino based home build cnc

Thanks again Vaughn

Laser etching #pcbgcode

bruce q
 

I have been using Eagle and PCB-Gcode for many years now with good results using a cutter to engrave the PCB traces.
For the past couple of days I have been trying a slightly different way of using PCB-Gcode to make these PCB tracings that I found
on another site (Hackaday or something like that) where a laser is used to cut thru a thin vinyl film to create a mask for etching.
I have done this twice now and the second time , learning from the first, came out much better even though it wasn't much in
traces and pads. I use a 2.3 watt solid state laser and the vinyl I bought from a sign making company. I use a Arduino UNO loaded with GRBL
for the controller and bCNC to send the Gcode to the controller.
I have had to modify the G-code generated to take advantage of the adaptive laser power depending on feedrate while it travels making
the outlines just as if you were using a cutter. So I guess this is a wish list item that perhaps someday can be added to PCB-Gcode for use
of a laser. One item in this case would be eliminate Z axis movement which isn't needed to using M4 rather than M3 to turn on the laser.
For now I guess I will start thinking about using a G-code editor to make the changes automatically if I can find one that will let me
do that sort of thing.
Thanks for reading,
Bruce

Can only get a single isolation pass around tracks #eagle #etch #pcbgcode

AlbertHall
 

I have ground planes on both sides of the board. Rtch tool size set to o.3mm.  As you can see below there are multiple isolation passes around the drilled hole but only a single pass around the tracks (except where they are close to each other).

How do I get multiple passes around the tracks, please?


Re: Can only get a single isolation pass around tracks #eagle #etch #pcbgcode

John Johnson
 

Since your tool size is 0.3, and step size is 0.15, then 0.3+0.15=0.45, which is over the maximum. You could try upping the max to, say, 0.5 and see how that works.

Regards,
John

That adds an extra pass around the drilled holes but the tracks still only have a single pass.

I have attached the board file if anyone would like to have a go at this.

Took your board and erased all your tracks and polygons, then set all the tracks to 0.4mm in "net classes" and all clearances to 0.4mm in "design rules". Ran the autorouter and chose the minimum "vias" solution.  Then ran pcbgcode with my own default settings and a 0.2mm 30degree engraving tool.

Examined the results using UCCNC toolpath display, and took the attached screenshot for your info. Note that there are some nets not routed, but you get the flavour of the results.
