arpruss / gcodeplot Goto Github PK

Hi again!

Is there any way to put somewhere some default config file instead of using switches?

Regards!

Looks like the changes have been made it code, but the zip available on the inkscape site still downloads an older codebase.

I wanted to draw a rectangular grid of cut lines in Inkscape and have it saved as GCode, but I got the error

Drawing out of range: [14.1846332, 30.78257099999999] [162.9988482, 90.782574]
No points.

The grid is straightforward:

The gcodeplot settings look sensible to me:

What am I doing wrong?

Here is the zipped SVG file for reference:
Velostatpads.zip

testing the new changes and I re exported a SVG I knew worked and I found an issue that has started happening since the new changes,

my setitngs are minFeatureThickness = 0.86;

It ignores that and makes it much much thicker now!

The issue is found in parser.py and gcodeplot.py. using the find & replace tool to replace all occurrences of "is not" with "!=" seems to have resolved the problem, but I have not been able to thoroughly test that this is a good solution and that it does not introduce any more bugs. attached are my modified parser.py and gcodeplot.py files.
gcodeplot_fix.zip

"The called script passed additional data to Inkscape. No error message was returned from the script, but the result may be unusable."

If I try to save s.th. to gcode I get the above error message. Even if it says that there are no erros, if I click "ok" the next message says that it was not able to save the file.

I am new to Inkscape, and I installed the extension per the instructions, but I get this error, so the file cannot be saved as .scad:

Any ideas?

Nice tool but what parameter is defining the width of the pen?

Files needed to reproduce the issue: gcodeplot-fpbug.zip

I commented out the "Drawing out of range" section to make the print work, and it turned out awesome. I think it would be better to add a tolerance here though (or just allow negative values, since they're not necessarily invalid).

Hi,

first let me thank you for this convenient way to use my 3D printer as a cutter as well! 👍🏻

I have a question on using it, though. Due to the nature of the blade's point running behind the turning axis, there are loops cut at sharp corners. Is there a way to avoid these? Something one could do in Inkscape to have the blade lifted, moved and lowered again at these corners?

The generated demoulding plate can be improved in two ways:
1. Take into consideration the insideWallFlareWidth. Right now, if the insideWallFlareWidth is larger than the minInsideWallThickness the demoulding plate will not go through the hole.
2. With multiple walls, the generated demoulding plate will consist of multiple pieces that will have to be used as a puzzle. This pieces could be connected together to ease the usage of the demoulding plate.

I've already implemented a solution for these problems, but I'm not experienced in GitHub and, of course, have no permission to commit my changes. Also, I've never done a pull request and don't know if that's the right option. So, if it helps, I attach here my modified svg2cookiecutter.py (renamed to .txt so I can attach it), and an example of the generated demoulding plate.

My plotter has (0, 0) at the center, so I want to be able to use negative X and Y values. So I set Left and Buttom to negative values. Unfortunately this gives my a "Drawing out of range" showing coordinates that are NOT.
I had a look at the code, but I couldn't find a obvious reason.

Inkscape version 1.2.2
GCodePlot version 0.12
Viewing in CAMotics version 1.2.0

Same file, text is set to path in both scenarios, only change is between drawing/cutting in selection before saving. Is it bug, or am I doing something wrong? It is not problem of CAMotics, if I send it to cut on Klipper managed Ender 3 Pro, I get the same result.

Hi friend. Thank you, for sharing this work.

Tell me, how to use your Cookie Cutter extension?
Reverse engineering of Python and OpenSCAD is too slow by me.

Best regards, alex.

The --safe-delta-z option is missing from the command-line help.

I haven't looked but there are probably other options that need to be updated too.

Python can generate command-line help automatically if you use a more full-featured library like argparse.

Hello. Thank you for a great project. I think the "Lift Command" and "Down Command" under the cutting settings tab for GCode creation is still under development? It seems as though after every small movement, the down command is written in the gcode again. Example below. I have to include a statement such as "M3 S25 G4P0.3" to add a delay after the down command due to using a servo for the up/down movement. Same thing for the lift command "G4P0.3 M5". You can see the output will cause major delays when ran. I am just trying to figure out a way to utilize the tool, but it may be beneficial to be able to add a delay before and after the actual cut path is started. It is hard to find a tool that has the overcut and offset feature such as your tool, so thank you for your work!

I have played with some other "laser" options for inkscape.
but this plugin is just so simple to use with my 3d printer

would it be possible to add Gcode for laser option?
i suggest adding a tab, and a couple of fields to where we can input the
desidered gcodes for for on/off (i use a fan code for instance)
then simply integrate instead of the pen retract?

Any way to add a field for custom start/end gcodes for those of us converting 3D printers with auto leveling?

Thanks!

there is any way to not generate gcode for hidden paths? right now is generated for all paths even if is not visible

thanks

Sometimes there is space in the end of viewBox property in SVG file.
So I suggest modify line 520 of parser.py to
viewBox = list(map(float, re.split(r'[\s,]+', svg.attrib['viewBox'].rstrip())))

I was searching for a gcode exporter for Inkscape so I can print smooth lettering/etc. and came across your project. I don't code well enough to be able to parse your code, but does it support the G02/G03/G06.X commands that generate curves for the hardware to interpret? That would both make the resulting gcode MUCH smaller while making the fabricated part match the original artwork MUCH better.

Here is the video that introduced me to the commands: https://youtu.be/18uYYXecH5g

I've followed your Instructables hoping to set up a vinyl cutter on my 3D printer, but ran into issue when trying to export/saving gcode. I've tried every setting combination and it it seems like this error only shows up when set to cutting mode, drawing mode exports a gcode file just fine.

Please advise.
Thanks

Hello,
Thank you for providing this extension for Inkscape users!

This is just to let you know that most 3rd party Inkscape extensions, like this one, probably will not work with the upcoming new Inkscape version, the long-awaited version 1.0.

Here is the info you need to update this extension, so that it will work with 1.0 and future versions.
https://wiki.inkscape.org/wiki/index.php?title=Updating_your_Extension_for_1.0

If you have further questions, you can contact Inkscape developers via mailing lists, forum, or the chatroom.

If you have already updated it, please disregard this message.

All best,
brynn

Would be nice to specify our own pre and post commands for gcode. To make this more generic, I think perhaps the code out of the box should just zero out XYZ axis so all the user has to do is move the pen to the bed and hit print. Could you provide some input on what files would need to be changes to allow me to add pre and post gcode command instead of the ones currently in use?

There appears to be a command line flag to set the safeDeltaZ variable, but this flag is undocumented in the usage (-h) text.

When I use Greek characters i get the following error when I try to generate the gcode, if I remove the Greek characters it saves normally.

Hi, i am trying to convert your python code to javascript, and result in weird path data.

I enlarge the sample path and offset is 4
paths = [[[0,0],[20,0],[20,20],[0,20],[0,0]]]

I try copy the python data result also the result is like that.

Here's my code
Gist code

I am planning to make a GCODE CNC generator from SVG, with tool offseting.

Thx

Hello Alexander,

First of all, thanks for sharing your wonderful tool. I've been playing with it for a long time now, converted it to work on my DIY pen plotter with custom gcode injection for header and footer and more.

Now, there's only one thing that I haven't been able to get to work, and that's pen changes. How do I set up my inkscape file for that? I have a custom gcode snippet I want to insert in the gcode output file whenever a pen change is needed, the most important thing is getting the script to actually recognize when a new pen needs to be selected.

Does it simply work by using multiple colors? (this didn't work for me, maybe I need to work in RGB instead of CMYK or is it some other issue?)
Does it work by naming layers? And what names should the layers have?

I hope you have a solution for me, my project is 95% done and the only thing missing is this pen change script.

See my prototype plotter here:

Thanks for your time,
Marinus

Hi! May I ask you for which printer does this program export the GCODE? I have an Ender3 which runs on Marlin firmware, will the GCODE be compatible? Thank you 😄

It seems that upgrading breaks this plugin completely. The object I have is definetly a path, but... alas, no points.
