Dev-version

You can try the newest development version by getting it from github repository https://github.com/cnc-club/gcodetools via web interface or using git clone git@github.com:cnc-club/gcodetools.git .
You'll need to run python create_inx.py to create inx files. After that install procedure is the same with the stable version.

Translations

Gcodetools is included into Inkscape v 0.49 so it will have native translations as other Inkscape's extensions. Until it is released you can use some self made translation packs:

I was wondering if anyone knows a way to move the Inkscape canvas to -Y. I do all of my milling in +X and -Y because it moves the gantry out of the way when it is at home-zero. If I could have Inkscape default to there it would eliminate a step. Now X0, Y0 is in the bottom left. I would love it if it could be in the upper left. Then when I process it in Gcode_Tools it would be in the right place. -Thanks

Try to move grouped orientation points above the page, will this be ok?

Are you using the latest version of inkscape? We have a report of the same error which had appeared in some dev versions..

You can get it with inkscape (latest version), or you can get dev version at github: https://github.com/cnc-club/gcodetools

Thanks for your reply, it was un unstable version. Now with the 0.91.0+47~ubuntu14.04.1 (stable release), no error message.

I'd like to get better at greyscale to depth. I want to be able to mill areas at different depths and it would be even better if I could set a gradient from white to black on an area and mill that sloped. (that sounds way to hard to code to me though).

I see you can change the depth function to c*d but it looks like the area function won't pick up the color of the underlying shape so i have to select the milling paths and change their stroke color lighter or darker to get it to mill them at different depths. Am I thinking correctly? If so, can we have that feature ie the milling paths get their color from the underlying shape (or I guess you couldn't see them then so maybe a complimentary color of the same intensity)?
Thanks,
Robert

Hello,
Is there a way to create drill holes using Inkscape .91pre4 with GCodetools? I drew circles for 5/16" holes with solid FILL and no Stroke. Using a 1/4" diameter tool in GCodetools. I ran the generated gcodes with a Pen tool to see what happen. Looks like its cutting/drawing outside the circle. The cut would have created a much larger hole than 5/16". Should I set my circles to 1/16" diameter and still cut with 1/4" bit? Does GCodetools support drilling operations?

Thanks for your help!

[Nick]

Does GCodetools support drilling operations?

Yep, use DFX-points for that, you will got a drill in each point.

[tony_4]

guys please i would be very gratefull if someone could make the G-code for me and send it to me here. It is a simple 24 teeth gear, 15.0 mm tooth size, 10.0 degrees pressure angle and a 30.0 mm diameter of a center hole. I know this is very easy for you but i really can dot it by myself. Thank you very much i hope to receive an answear from you soon.

Hello Guys!

I have a Default tool defined setting the "passing feed" to 999. But my gcode file does not contain 999 as a feed rate anywhere.

Below is just the first several lines of the file. Z safe height = .25" so I thought between each path after "G00 Z 0.2500" would be the passing feed rate of 999. How and where does passing feed get used?

Thanks for your help!

Just try to use Inkscape's Gear extension it's fairly simple.

To be true, I do not know how does Passing feed works, but I know that all moves at G0 are made on the Rappid speed that is defined by your machine controlling software (Mach, LinuxCNC, etc.) And "F" do not influence at them.

Hello Nick,

Is there a way to get all the Tool parameters added as comments to the gcode output? I know "(Change tool to Default tool)" is generated. Plus there is "tool change gcode" for entering custom function name. But it would be nice to have all the parameters used when generating gcode available as comments maybe inserted before the header.

For debugging and documentation purposes a "verbose comments mode" that dumps all parameters into comments would be great.
Not only tool information (like diameter, feed, shape,passing feed,depth step, etc) but also the original document name (.svg) too.

GCodetools is good stuff! Thanks for all your help!

[Nick]

Hmmmm im not sure about that... there's an option to generate additional log file, that will contain more information.
See last parameter in Preferences tab.

Hi,

I have started using the gcode extension for inkshare, its great, thanks for sharing it!

I had a question, its really simple I am sure. I am finding it hard to see where to adjust the depth of the z axis in the extension options.

Currently it always exports with z cutting at 0, I need it to cut at -45.

Any help appreciated,

Adam

[Nick]

I am finding it hard to see where to adjust the depth of the z axis in the extension options.

it should be in the orientation points... But either you should add them every time manually (using Orientation points), or change it in the orientation points using text tool.

[adamguy]

Thanks Nick,

Found it. This is a great tool and perfect for what I am doing.

Hi

I am trying to create G-Code where it will fill in the text for me as well, and not just the outline.

I followed this youtube clip: https://www.youtube.com/watch?v=AxUF9T53zSA

However, after I click Apply to the 'Area' screen, I don't get the same as in the video. Instead I get this (see attached image).

What am I doing wrong???

[Nick]

Gcodetools uses Inkscape's internal offset, which sometimes sux...
You can try to limit offset ammount, and reduse offset step... And correct manually any bugs later.
