I get this when loading an svg or inkscake svg
Same file in LW1 works ok.

Since the last merge, files that generated the raster and preview and gcode in less than a minute are now taking much longer (5 -10 minutes to complete the process, or even causes a hang sometimes). The raster seems to generate just as quick, but creating the gcode and displaying the preview seems to be where the bottleneck is. Not sure what has happened, but it definitely feels broken.

After saving the selection nothing happens. Only after refresh

I have a CHIP that I invested in a few months ago, and I feel that it would be perfect to serve as the head for my laser cutter. However, I'm running into difficulty figuring out how to get the software running as a local ad-hoc server (similar to the octopi project). Does anyone have any insight as to how to get this running in such a way? Or might I be completely off base?

Convert to maintain scale from source design a

@Gustavvr wanted to help out so creating issue to track this
Notes:

Add a configurable field to https://github.com/openhardwarecoza/LaserWeb2/blob/gh-pages/index.html#L560 (handle the saving and loading to Localsettings here too https://github.com/openhardwarecoza/LaserWeb2/blob/gh-pages/js/main.js#L193

translation functions: https://github.com/openhardwarecoza/LaserWeb2/blob/gh-pages/js/fileprep.js#L77 - here it puts it at 0,0 - but if we implement the Origin change we need to do that calculation here...

The way the gcode generator works in LW2 is that we create and move the threejs objects to where we want it. When I run the gcode generator over the threejs geometry it does a localtoWorld to get the coordinates in the scene for each vertex (: (so less math)

Is it possible to change the layout of this buttons to reflect X and Y in a cross pattern instead of side by side?

When I open an SVG file, it correctly places it in the upper left quadrant, but bitmaps always open on lower left quadrant.

Can we get LW to show the file name in use

@openhardwarecoza I just want to know if you have any thoughts on this issues before I start making changes.

The Go server portion of SPJS is binding to only IPv6 on my computer ( I use IPv6 so I don't want to disable it) The spjs.js file in LaserWeb2 does not support IPv6 address format ( e.g. [::1] ). I can look into resolving this. But I wanted your input before making changes.

When I try and load an svg file I get the following error:

TypeError: Cannot read property 'position' of undefined
(http://openhardwarecoza.github.io/LaserWeb2/js/fileprep.js on line 72)

I need someone to help moving raster from laserweb1 to laserweb2

1. On load of bitmaps https://github.com/openhardwarecoza/LaserWeb2/blob/gh-pages/js/main.js#L90 catch the event and load it to a div behind the 3D viewer (pay attention to how I handle svg and dxf already in https://github.com/openhardwarecoza/LaserWeb2/blob/gh-pages/js/main.js#L101 for example. raster functions are still global but in a different .js file (dxf and svg for example sits in js/dxf-render.js and svg-render.js) like we used to do here: https://github.com/openhardwarecoza/LaserWeb/blob/master/i/main.js#L2416
2. hide the https://github.com/openhardwarecoza/LaserWeb2/blob/gh-pages/index.html#L293 cam module and show a new module (raster setup) (copy the module in index.html) with the raster settings
3. raster still works like in LW1

Other important places in old code https://github.com/openhardwarecoza/LaserWeb/blob/master/i/index.html#L110 and
https://github.com/openhardwarecoza/LaserWeb/blob/master/i/main.js#L2494 and https://github.com/openhardwarecoza/LaserWeb/tree/master/i/raster contains most of the functions

settings module:
https://github.com/openhardwarecoza/LaserWeb/blob/master/i/main.js#L2428 and https://github.com/openhardwarecoza/LaserWeb/blob/master/i/index.html#L849

Preview size bounding box https://github.com/openhardwarecoza/LaserWeb/blob/master/i/main.js#L2521

Another cool thing in LaserWeb2 is a new progress bar - https://github.com/openhardwarecoza/LaserWeb2/blob/gh-pages/lib/gcode-viewer/gcode-parser.js#L208 for example. See
https://github.com/rstacruz/nprogress for details - which looks a lot better than the one in LW1

Selecting SVG produces the following " ReferenceError: drawSVG is not defined (http://openhardwarecoza.github.io/LaserWeb2/js/googlesignin.js on line 123)"

DXF load without issues

BMP and jpg don't show at all

Maybe show a pop-up like touchpad to select file im afraid that a long list will move the whole left side of the interface down.

Did you apply a maximum? I just added a folder inside the drive and reduced the files showen minus one but does not show the folder

Consider adding 250000 baud as an available option. It's a common baud rate, and seems to be more stable than 230400 for some users on USB serial UART clones.

Creating the communication layer between laserweb2 and TinyG - TinyG2

• handles all communication and parses all the messages
• stores all controller settings into TinyG object
• make it tested
• pre installed command for homing, resetting, ...

Information

• communication for settings

If I open a bitmap and generate the raster, then change the dpi and re generate the raster, it overlays the new view over the original view.

Open a large image, like a HD photo in jpg, png.
Generate raster and keep track of the browser's memory usage - it will grow with GBs when the path rendering is created. For a large enough photo the browser will crash.

I assume that the problem is in the area of number of THREE lines, a 1000x1000 photo may need 1 million lines with bad luck, usually less, but a lot of lines anyway.

I have no working experience with THREE but I assume it would help to group the lines into lines with many vertices with different colors.

I intend to look into this the coming days.

I am in the process of testing LaserWeb and am choosing the controller firmware had hardware, however there do not seem to be any clear directions yet.

Based on tickets support for Marlin/Smoothieware/Grbl is under development and thus would be a good idea to nicely display what id the default, most operational path.

Happy to prepare this, just ping your replies which firmware should be the best choice.

@rafffel reminded me that we want LaserWeb to eventually be a full cam solution:

https://github.com/openhardwarecoza/LaserWeb/issues /118 relates.

But basically, the framework is there

1. We need someone to help work on adding the drag knife rotate moves
2. We can do mill/pocket operations using the clipper offset paths code already in there.

js/threegcode.js is your friend (:

I'm trying to do an engraving with the file / raster generator. I'll see in the other issues that the feature is working, but I actually never managed to generate gcode from a raster image. All I get is this:

One straight move.
What do I do wrong?

If i load a file but then change the original and load again without refreshing the browser it wont update itself. This can cause problem while connected

I am putting object at 0,0 on scale and offset tasks. Doesnt always worth though so needs rethinking. Positioning is ignored on these moves too.

So i open a file, generated the code the open another file and the previous gcode is still there.

More over when you go to convert to generate a new code it keeps showing and accumulating the previous one. Is this by design? It does execute the correc one.

How to run the LaserWeb2 locally on Rasspberry Pi.(like LaserWeb2)
Which server(app or software) need to installed.
Can you help me?

@cojarbi submitted a SVG that doesnt work

Openbuilds_Blackbox_Logo.svg.zip

Sliced results edges are on top of each other.

I think my issue is specifically with Marlin, but I am seeing artifacts in some grayscale burns. It is not due to acceleration as I have tried constant feed speeds where no acceleration is needed. I think the issue might be with the 16 command look ahead limit in marlin. If there are to many pixel intensity changes to close together, the laser stops moving for a split second as marlin catches up. The reason I think this is the issue is because I do not see a problem with the calibration pattern which does not have a large number of intensity changes in very quick succession. Has anyone else seen this?

When I set the quadrant to top left, SVG files are placed correctly, but bitmaps still place in bottom left.

Maybe I'm just too stupid, but how do I start LaserWeb2?
The instructions from LW1 don't work:
´´´
C:\Users...\LaserWeb2>node server

Found this on the web:

If you implement this in the overall design, I can go through and add context sensitive tool tips where they make sense, makes for a much more user friendly app in my opinion.

This is a complete dump of the terminal running a complete job.

Tested 57600, 115200, 230400 and 250000 ( this last one did not connect )

Always chokes on 300 aprox lines remaining in the queue
Smoothie with marlin buffer.zip
.

Zoom in to the raster and youll notice that the calculated path has slight offset to the left.
Is this:
affecting the actual location of the raster
its a bug from the image preview
Its part of the code originally intended by @nathanielstenzel
Else?

We might have to think about a laserweb api.
Otherwise this will become hard to maintain.
Here some quick ideas.

laserWeb.settings = {...} // object containing all the settings
laserWeb.settings.set('x', 15000) // a way to set the settings, this way we can also trigger events
laserWeb.settings.set('homingCommand', '$H') 
laserWeb.controller.home() // home your machine

laserWeb.raster
laserWeb.dxf
laserWeb.gcode
laserWeb.controller

laserWeb.trigger('WPos',{x:231,y:541,z:9})

This is more testable :-)
The UI would hook into the laserWeb object

It would be great if raster engravings could be output in G7 format as done by Turnkeytyranny. The advantage over a number of G1 commands are first of all faster engravings due to different internal handling. A proper implementation in the laser controller will also make sure that intensity stays correct even when accelerating motor or if motor should stutter.

I dont think this is a big effort, laserraster.js need some additions. The syntax is rather easy

• position head lower left of image with G1
• set raster and laser options: intensity and pixel size with M649
• every bitmap line is split into 51 pixel chunks, which is output in the G7 command in base64 format, in javascript btoa() does that. The data is the pixel grayscale intensity in the range 0-255.
• add $1 or $0 to change line and tell to move right or left.

Need help from a grbl owner with a bit of JS experience to add some more if statements below
https://github.com/openhardwarecoza/LaserWeb2/blob/gh-pages/js/spjs.js#L197

you can get sample code from https://github.com/openhardwarecoza/LaserWeb/blob/master/server.js#L329 and https://github.com/openhardwarecoza/LaserWeb/blob/master/i/main.js#L2011 - I just dont have a grbl machine at hand to test with :)

In laserweb1 we had the functionality split between server.js (pushed it as posStatus to main.js) and main.js (updated UI) - in laser this just all happens in the frontend - otherwise mostly copy/paste

Error after pressing prepare raster

ReferenceError: startgcode is not defined
(http://openhardwarecoza.github.io/LaserWeb2/js/laserraster.js line 77)

Added G92 in LW options thinking i had to. Same result

All the jog buttons work, however I cannot make it home using the home button. Also the abort job button only works about 50% of the time for me.

The travel moves setting does not want to save after I enter a value of 1000. It reverts to the greyed out default of 2000, and keeps telling me I have an incomplete config file.

I keep getting this error when trying to open bitmaps:

TypeError: evt.target.files[0] is undefined (http://openhardwarecoza.github.io/LaserWeb2/js/main.js on line 391)

I have tried about 30 different bitmaps, always with the same result.

If I open a file, then open a second one, it does not clear the first one from the display, it overlays the first one over the second one. Then if you open a 3rd one it overlays over the first 2.

In grbl you can receive the size of your cnc by asking the settings. The grbl object already contains the size of the cnc after you send $$ command, by storing all the data into it's memory.

It could or should set the size of the cnc in laserweb.

Since I'm gonna start implementing the TinyG & TinyG2 object, we should think about a flow to retrieve data from our controllers to have a validation layer in laser web that generates better gcode that does not try to go faster or is not going to hit the limits of the machine.

I will gladly wait a few more seconds for the gcode to be generated if I can get X seconds back with an optimized Gcode (for batches with more than one run)

There is a few command line toolq on github too.

@mkeyno so lets talk (:

I can compile lw2 down to a single file. We are also working on Fabrica, see arthur wolf's posts on google plus (follow me on google plus too).

That parts easy. Hosting the file from an esp, probably possible but it could be a few mb so we'll have to see.

The first thing we need is a websocket server to serial bridge on the esp8266 first. You can't telnet from the browser and http requests have too much overhead.

Once we have that, i can start porting the code from laserweb1 since its node.js app acted as websocket to serial bridge.

At the end of the day, dont worry too much about it. You can already play with laserweb2 live on http://openhardwarecoza.github.io/LaserWeb2

We need to prevent refresh page if isconnected

Calling @lautr3k...

See https://github.com/openhardwarecoza/LaserWeb2/blob/gh-pages/js/grbl.js and https://github.com/openhardwarecoza/LaserWeb2/blob/gh-pages/test/grbl.js

Do you feel up for for helping out? (I'm thing smoothie-happy)

Joe ( @prcdslnc13 ) reported that LaserWeb2 on Windows fails to connect to the device. We need to get rid of the /dev/ (;

I started with a big svg, scalled it, set tool offset to 0, then changed position.
Hit generate G-code. position is ignored
Change tool offset to 0.1 or more or less then hit generate G-code. position is applied.
