Great stuff,

I've been using Vectric's Cut2D and Cut3D with my CNC Router, which I've now moved to a common maker space and have been searching for open and accessible tools that we can put on the resident Ubuntu machines, or that users can run on any OS they happen to have. Your Gcodetools plug-in looks great. I've spent a few days with the tutorials, and have managed to get the area tool to create the paths I expect, but I have a question, well two actually.

1)
Can I specify a step over or overlap parameter somewhere? So for instance if my tool is 10mm wide and I want a 60% step over, then the path's are only 4mm apart.

I'm not sure if this feature exists, and I'm missing it because it's named something else, or if it hasn't been developed, or needs to be manually produced by running the tool again after offsetting the size of the object I wish to cut out by some factor for smooth pocketing.

Let me know if this is unclear and I attach images of what I'm talking about.

2)
In the tutorials you mention that the area width is always in pixels, and the units setting (in or mm) does not matter. My question is, is this the only parameter that is not based on Inkscape's units setting? I use inches and set the tool diameter as such and it seems to work as expected, but wanted to know if there would be other non-inch based parameters.

Thanks again for the great tool.

Pete

1. Yes there's such feature, but it's in the development version...
See 5 posts above :^) http://www.cnc-club.ru/forum/viewtopic. ... =120#p1327

2. As long as Orientation points system was implemented you can use any units you want. Just make sure, that orientation points are in place.
So if you create create area curves with Area tab from gcodetools you wont have to do any unit conversations.
By the way check out our new Area fill function which fills the path with straight lines, so there no need to do any difficult path offsets:

Excellent, not sure how I missed the the offset feature, that is exactly what I was hoping for, the Area fill looks very promising too, I'll pull the development code and check it out, thanks. I'll likely be pulling some documentation together to give a tutorial to the members at my maker space. I'd be happy to contribute it. what's the best format and way to do so.

That will be great! You can do in any format that suitable to you. And you can place it wherever you want, either at your own site (and give me a link to link it from the main page) or here at the forum.

Hi folks! I'm trying to use g-code tools v1.4 in Windows, with Inkscape 0.48.0 r9654, but it seems that nothing happenes, unfortunately!

I tried c: with and without backslash, and "C:\Dokumente und Einstellungen\bo\" (my home dir), with activated logfile as you can see in the picture, but no file appeared there. Also on the screen nothing happened, no matter what values i set for tool diameter and area radius. I also tried version Gcodetools 1.6.04, where the 'what to do' section is missing, and it also didn't seem to work.

Has someone the same problem, or any idea?

Those are the tutorials I found:
http://www.cnc-club.ru/forum/viewtopic. ... t=82&p=993 from root
and other one from 10 Dec 2009, 10:28 and also this (http://kalyaev.com/2010/20100402/tut01/tut01.html)

cheers;

Edit OHUH think i found out, it must be a general problem because none of my extensions work! I was just reading http://wiki.inkscape.org/wiki/index.php ... onsWorking but maybe I'll install all again.

servas!

Nick · Сообщение **Nick** » 04 янв 2011, 20:58

You better use v1.6. we've split all the functions to different extensions/tabs (tab is a "page" in the extension's window).

So for example if you want co export path to Gcode you should open Path to Gcode extension from Gcodetools, fill in filename and dir, chose the Path to Gcode tab and press Apply.
Now "what to do" equals to active tab. So if you want area function - select Area tab, if you want Gcode select Path to Gcode tab.

If extensions do not work at all, try looking here http://wiki.inkscape.org/wiki/index.php ... ft_Windows . Gcodetools is a ordinal python script so all you need to make it work is to have an Inkscape and Python. So check if Python have been installed. (It should have been installed when you've installed Inkscape but may be something went wrong

)

PS if something goes wrong Gcodetools usually raises an error so you should know what exactly goes wrong.

Ah ok, think I got it now, it's probably easy when it's running. I'll have a look in the future.

Anyway thank you for the reply and for sharing your work! cool!

Dear all

I'm great fan of cnc-club and milled several projects so far. Yesterday I experienced a problem. The code seemed to be finde on EMC2 (Ubuntu 10.04). But when milling, it follows on a huge radius, when I understand the G-code, see picture and see what I mean. (I tried two fonts, Comics Sans / Tlwg Typist)

I tried several settings, even with Windows and on a Linux Computer with inkscape 0.48 and the stable Gcodeplugin 1.6 as well as the newest dev. revision from 17.01.2011.

I'm sure, I do not understand some parametric settings. But I have no idea where to adjust.

I'm really happy to every answer and hint where I need to fix that.

By the way, it's a fantastic tool! Congratulations to the developers!
Bartelime

Thanks for the report could you attach you svg file?

I'll try to find out what's wrong.

PS I've heard about same situation while using Engraving function...

Wow, ultra fast reply!
Thanks and find the file attached above!

Nick · Сообщение **Nick** » 20 янв 2011, 17:52

I've made a test of the "Reinigung" word and it was fine, probably it's because of different parameters...

Could you attach an ngc file to

.

PS I've posted a question about same bug from another user at the LinuxCNC.org - EMC2 developers site. And now waiting for their answer to ...

Hi !
Ill try to test new dev release of gcodetools , first the lathe extension but nothing work.
And after just the path to gcode and same problem ??? Inkscape 0.48 on Debian.
The svg is just a spriral , Two orientation point set with gcotools dev 1.6 last rev 173.
And standard tool... and i have nothing done and no errors...if I'll set the option direct viewing and then I have :

Hmmm sounds strange.

I've just checked the Lathe function. And it works fine. May be you have defined wrong lathe width parameter...

And what's the "direct viewing"? Is it a kind of "Preview" check box at the bottom of the dialog window? If yes - it does not work

! It is needed only for enabling editing the scene while extension's window is opened.

PS here's the screenshot of lathe:

By the way in the development version there's a new function: modify path, to prepare the path for cutting with straight rectangular cutter:
Red path is the trajectory, black one is needed cut.

And a simple test path made with gcodetools:

alfcnc · Сообщение **alfcnc** » 21 янв 2011, 00:54

Yes very strange !
I have ever test with changing all the parameters... I'll have done so many test when debugging lathe function...
But with other function it's the same ???
I have test on ubuntu same problem ???
I'll try to find...
Which version of inkscape do you use ? 0.47,0.48 ? dev ? on win or Linux ?

Сообщение **admin** » 21 янв 2011, 01:00

There should not be any difference what version to use, 0.46-0.48 windows/linux.

Attach your svg, and I'll try to find out what is wrong...

Nick · Сообщение **Nick** » 21 янв 2011, 01:32

Hmm... Works "fine" at my side.
"fine" as fine as could be cutting such spiral on lathe

.

But I've tested it at home on dev version at one of the latest revisions but not the last one, I'll try it on the last revision tomorrow at work.

Do other extensions (not Lathe or not Gcodetools) work fine, or not?

alfcnc · Сообщение **alfcnc** » 21 янв 2011, 01:36

I'll come to test on Debian same version but Inkscape 0.47 that's ok....
It's my Inkscape 0.48 on this computer who make things out of order...Excuse me !
Thank's a lot for speedy reply.
have a nice day.

Probably there's a problem with Python or smf...
