Cool Project. I was wondering what resources (research papers, books, blogs etc...) you used to start developing your own CAM software. I am interested in creating my own toolpath and any insight to your learning process would be much appreciated. Thanks.

I appologize for such a question, but this is the first time I see an AGPL/MIT dual-license. I wonder what does it actually mean and under which license the derrivative code should be licensed?

Hey.

You have quite an interesting project, and VisualCam in particular is interesting.

Would you be willing to give me an open source fork to work from?
I am in particular interested in extending your dragknife support, and more 3D milling.

We also use a threejs+clipperjs backend on Laserweb

Laserweb has quite a bit of traffic - which could help bring some fame. (We even have a sponsors WIKI page that has managed to nett some of the contributors machines, boards and paypal donations - i'd be happy to put your details on there if we use some of your code. )

The following g-code has a 90 degree arc from Z to X. It looks like the arcs are going in the wrong direction:

Thanks for the awesome tool, I'm using it to proof my G-code before trying it on a real CNC. I don't know if I'm missing something, but it appears that circular interpolation endpoints aren't completed properly when followed by a G0 or a G1. I think it's easiest to just show you an example. Pasting that code into the simulator, you can see that arcs in the XY plane terminate early, and the G0 to the clearance plane (Z0.25) is diagonal instead of vertical. This happens on the bottom of the eyes as well, when a G2 is followed by a G1.

When using the instruction G42 D1 the webgcode app seems to not recognize the command. This however should be valid gcode (at least it seems to function as expected in the CNC machine I'm learning with).

Note however that everything still seems to function well so it's just a "minor" bug.

I was wondering if the editor could do automatic line numbering as I have explained here?

Hi
You did wrote that this is the contact space when someone needed to contact you.
I use your code on my CNC website, its it freaking awesome programming you did there.
As I interpret it, this software is free to use. (?)
Did some beating on it, but the major deal it's your code.
I'v putted it on http://www.tomasw.com/gcodesim.
and again, really good job :)

I think that this might be inverted:
https://github.com/nraynaud/webgcode/blob/gh-pages/webapp/cnc/gcode/parser.js#L288

i.e. it should add the offset to the new point, not subtract it.

If my thinking is correct, I'd expect this g-code to create a 10x5 box with a 8x3 box contained within, but right now it creates a 10x5 box with a 8x3 box offset(starting at X-2Y-1):
G1X0Y0Z0
G1X10Y0
G1X10Y5
G1X0Y5
G1X0Y0
G10 L2 P1 X2Y1
G1X0Y0
G1X8Y0
G1X8Y3
G1X0Y3
G1X0Y0

First of all .. great tool especially for a smal lab that has many processes on minimal amount of flexible machines.

As a feature request i would suggest adding the tool-chance as an option on each of the processing steps. If not selected default tool prevails.

Is this gcode GRBL compatible? We standarddized all machines to that for simplicity.
How is the STM compared to Arduino boards?

Thank you!

Hi,
I have tried out webgcode simulator. But I can't paste my gcode onto the left window since there is no left window to put the gcode.

How can I make it show the left window to put my g code ?

I am making my own CNC board. My firmware is in between GRBL and Smoothie also something like a mashup of them. Though I have a g code viewer on Windows OS, I need to make a some G code community site where popular milling operations G code are exchanged like Thingiverse.

Regards,

Paul J

Wonderful web application! Is there a way to get the data used for plotting the graph from your app? Thanks

Hi there, was wondering if you could assist me in using your simulator to draw pancakes.
Thank you,
Miguel

Two turns helix expected..

It would be great to have support for the G5 command provided by the Marlin Firmware (http://marlinfw.org/docs/gcode/G005.html)

Thanks in advance,
Herbert

I added this great software to the Alternativeto.net website:

https://alternativeto.net/software/webgcode/

Please help me by editing the profile and adding more information. Also if there are commercial / proprietary alternatives please add the software as their alternative so it will be seen in more searches.

It would be great if I could follow you on Twitter.

Fails with '%' in comment.

Example:
G1 Y14 S1000 F60 ; Move 04,14 laser 100%, speed 1mm/sec

Looks like it terminates the program?

Hi there,

Is there an email address to contact you with?

Visualcam on Firefox works nice. The UI is pretty intuitive. I've seen the gcode generated by VisualCam on webgcode viewer correctly.
Is there any online manual of VisualCam ?

Suggest replacing the "Load a bigger sample" button with "Load a new file" and a file upload prompt. I do most of my model development and conversion in Linux, from the command line. Therefore drag and drop isn't a good option for me.

If the "Load a bigger sample" function is still needed then this should be replaced with a link to a downloadable file.

See also #17.

Great software! Unless I'm missing something I can only view my output if I paste my code into the text box on the website. Would it be possible to have an 'Upload' or 'Open File' button so that I can select my file on my PC and have it uploaded and rendered?

Thanks!

Your simulator is the only one I've found that correctly simulates G2 with an X, Y and Z value as the endpoint.

Your simulation matches exactly my 3D printer connected to a Duet controller.

Depending on device webgcode app can take a considerable time show a UI all while showing no visual indication that it's actually still loading.

It would be a welcomed enhancement if it would be possible to show some kind of progress indicator while while the app is loading up it's UI.

This is a low priority enhancement request.

Hi,

I tried to open your link http://nraynaud.github.io/webgcode/webapp/visucamTest.html# but the login does not work so far.
i tried this in Firefox as well as Chrome.

Thank you

When writing the code G02 Y20 simulating it will lock webgcode tool in a permanent simulation cycle.

These commands should be the same as G00 X0 etc.

G28 (homing) is not recognized as a command. If there is a reason, maybe you can enlighten a beginner in GCode why?

M. Raynaud,

I have recently been using your online G-code simulator and would like to request your permission to use screenshots from it in a book I am writing for MakerMedia (Make:). The book is about using digital fabrication tools like 3D Printers, CNC, laser engravers, vinyl cutters, etc. for leatherwork. I would like to reference your site in the book as a tool for users. The book is coming out in Sept. of 2017.

I have previously published 'Make:Fire, The Art and Science of Working with Propane' for MakerMedia (https://www.amazon.com/Make-Fire-Science-Working-Propane/dp/1680450875) and am a regular contributor to Make: magazine (http://makezine.com/author/tim-deagan/).

Please let me know if you have any interests or concerns. I will only use screenshots from the site with your permission.

Yours,
--Tim

Sometimes when I open "https://nraynaud.github.io/webgcode/" I get a page with only some text. This is the error I get in the console (Firefox):

Error: Load timeout for modules: Ember,templates,libs/threejs/OrbitControls,libs/threejs/CSS3DRenderer
http://requirejs.org/docs/errors.html#timeout

The button "Load bigger sample" on the webgcode application loads a massive gcode sample and immediately simulates it which on low powered devices makes it look like the app stopped responding or just hanged.

The proximity to the regular Simulate button also means there could be accidental presses specially when using mobile touch devices.

I would suggest that the button be removed and replaced by a menu that allows loading the sample (and maybe other examples) of gcode into the editor so that users can see the code and only simulate it when the user presses the Simulate button thus avoiding accidental "lockups".

This is a low priority enhancement request.

Currently I'm using the webgcode web app on a phone and the interface could be slightly improved for it with possibly minimal work.

The enhancements I'd like you to consider are:

• button to clear the gcode (delete all text)
• button to download gcode as a text file
• making the previews show bellow the code editor in small screen size devices (or maybe a tab?) and allow the code editor to adapt to the width of the screen

These are not the only only improvements that can be made but possibly the easiest/fastest to do that would provide the greatest usability benefits.

I am trying to add gcode loading to the system. Please, help. It is difficult for me.

Hi @nraynaud ,
I like your 3D GCode-Viewer: http://nraynaud.github.io/webgcode/ and I thought an Octoprint (https://octoprint.org/) integration would be nice.

What do you think?

There is a g-code simulator here: http://nraynaud.github.io/webgcode/

Is there a way to have the g-code simulator run from disk (offline)?

Simply downloading it and starting it does not work:

• it looses all the interactions in the "black" areas (canvas, svg, ...)
• it stores the pasted g-code
• but cannot paste anything else

Any hints?

Downloaded (offline)

I decided to try webgcode locally using Chrome but there was an error in index.html saying

Uncaught DOMException: Failed to construct 'Worker': Script at 'file:///home/jalovisko/dev/webgcode/webapp/worker.js#3DView' cannot be accessed from origin 'null'.

Searching revealed that Workers don't work locally in Chrome, and indeed the page loads nice and clean in Firefox. However, I see here on Stack Overfloww a workaround for Chrome which I think sounds easy to implement. I can fork and fix this one if it's ok.

Using the mouse wheel to zoom in/out on the gcode rendering doesn't work well because it only scrolls by ~1 pixel for each step of the wheel.
