Hi!

It seems to me also does Eagle is the problem maker, but if I dig a bit deeper I can say Eagle is not the problem maker.
The trouble you had was because of win10 and all that, for me a bit "over secured" setup of win10.
It looks like some permissions restriction was active for the folder where Eagle was installed, and because of not enough
access privilege for the user who was logged in in your win, you can't access that Eagle path.
That's a very often problem in win10.

After many install/uninstall attempts I have finally got it working.
During Eagle install it offers to install to 'C:\EAGLE-7.6.0'
Changing this to 'C:\Program Files\Eagle-7_6_0' and all is well.
It seems to be the 'EAGLE' in all capitals that causes the problem.

Ok, thank you.
I realized what was the problem why I can't generate the gcode?and why was my preview windows empty all the time.
Eagle is simply unpredictable what settings are used each time you open it.
In my case, a checkbox was unchecked under:

Option->Set...->Misc
There is an option "Ratsnests processes polygon".
If this option is not checked the pcb-gcode?won't do the job.
You won't get the gcode and the viewer window of the pcb-gcode app would be empty.

Actually, the menu "Set..." is some kind of "Settings" menu.
Why the name "Set..." this is a mystery.

Again, I use the Eagle 9.2.2 version and at this moment the pcb-gcode?version 3.6.0.4.
I also checked all other versions of pcb-gcode?what I found on the net, and they are all working
On Eagle 9.2.2 and with the most up to date Java version which is in my case Java version 8 - update 191.

I hope this will help somebody in some time...
My best regards.

To answer your question about the requirement of polygons, I have made boards without them.? So the answer would be no they are not required.? Having said that, I usually do use a groundplane polygon as it can save me some vias etc.?

Thank you for you replay, I realized already does I made a typo error in my post #7875.

I wrote: "...I have not Java 8..." I mean I have now Java 8 on my machine...
Sorry for this.

I have another question about pcb-gcode?app.
Must I have a ratsnested?polygon?setup on my pcb to have the ability to generate the gcod?with pcb-gcode?
Do I need any polygon as a board layout or ground plane of my pcb?to generate the gcode?with pcb-gcode app?
Or can I just draw my traces on the bottom side or upper or whatever side I wish and the app can generate the gcode without a border line?

Thanks.?

Perhaps a Windows user will chime in.?

That’s a possibility, though it worked before changing Eagle.?

Could this be a Java error?
I have not Java 8, is pcb-gcode compatible with this version of java?

Hi!

I'm new here, so pls forgive me if I post this into the incorrect place...
Here is my problem:

I used Eagle 9.2.0 until a few days. After AutoDesk released the new update 9.2.2 of Eagle I updated.
After that, I can't anymore generate the g-code with this nice pcb-gcode?plugin.
That plugin worked for me like a charm.

I used the 3.6.0.4 version of the pcb-gcode?with Eagle 9.2.0.
When I updated Eagle and tried to generate a gcode, in the view window of pcb-gcode?
I never got to see the simulated?version of my pcb. I mean, the view window was empty.

Then I downloaded from here the 3.6.2.4 version of pcb-gcode?and added it to Eagle, in hope that will fix my problem.
But that was not the case.
With this version of?pcb-gcode?I got a much bigger problem.
When I was trying to generate the gcode?of my design, that was run into an infinity loop.
I have to wai around 30min to get my PC responding again, but the gcode?was not generated.

I replicated several times this situation.

So, what you think is my problem?

I use Windows 7 x64 and everything was fine... :-(

Thank you.
My best regards.

Just installed eagle 7.6 and PCBgcode on win10.
The PCBgcode files are in c:\users\jim\documents\ulp\pcb-gcode-3_6_0_4
The directories are set as below.
When I try to run PCBgcode I get the message as the subject above.? If I proceed regardless it complains that it can't access c:\settings.
Why is it looking in the root of the hard disk, please?

Can you show the preview image, and your setup pages please, then I might be able to help.

I have edited the output of PCBGCode. It is just text commands at the end of the day, so any text editor can do what you want. You just need to be able to read it, and understand what to do - totally an exercise for the reader :)?

Thanks to Art, Dan,?and Keith for your responces. Why? I asked this question was during a recent board cut I found that a small section did not cut quite deep enough due to the board having a slight low spot. I am experimenting in how close I can cut the just the copper off without losing much FR4. It would be nice if I could find just where my code was describing this area cut and recut at a lower z just in this area. I have been able to use autoleveling with my grblControl program for most of my boards so far and have some nice boards but on this particular board I used a .5mm endmill and had most of the board cut very finely removing just the copper, wow looking good!!! Ooops there was just a small area with contours which did not cut deep enough. Well I set the depth just alittle deeper and reran the whole program which has quite some detail so slowed me down just a bit. I would like to copy the blocks of code that details this area to a small new program then reset. Use my limits switches that set my home position which I use to position my (0,0) at my lower left mounting hole?and then recut lowering my z to remove the last bit of copper.
Has anyone tried this? Thanks again, Len

Hi Len,

Yes and no. If your G-code is absolute then that would be easily possible because each statement would stand on its own. "Go here" "Do this". However 99% of code generated by other programs use relative moves that use the prior position as a reference. So instead of "Go here" it becomes "Move a little more".

You should be able to see that if you stop G-Code execution, back up a bit and Go the next instruction will likely be "move a little more" from wherever the tool is at right now instead of where it would've been just before reaching that same instruction in normal execution.

What this means is normally, no, you can not just back up and redo.

If you want to do that you need to learn enough about G-Code that you can recognize the absolute moves that are lightly sprinkled about in most G-Code and back up specifically to that point in the code before, "continuing from here".

If there are no absolute moves (rare) then it's easiest to just re-run the entire job.

I have to do this because my Nomad hangs with the latest software driver.

Len,
In my experience, the answer is "maybe" LOL

A lot depends on the controller that your using to run the code. Some will do a decent job of starting in the middle of the code (as long as you don't try restarting in a G02 or G03 code. Start it at a G0 or G1).

From what I have read Mach does not like starting in the middle of the code, but YMMV. Best way to find out is do a test run.

Hi all, I guess I must be asking a unanswerable question. When I am using my gcode in the? cnc program can? I just rerun a portion of the code again without starting from the beginning? Anyone know if this is possible? Len
