I wanted to install and try Laserweb, but something’s obviously wrong, after I type “node server” i get a list of errors as in the enclosed image.
Can anybody help me with this? Thanks.
From my understanding Laserweb is an online tool have you tried loading it from the supplied website and not trying to run a local instance of it
Here are the instructions you need:
2. Type “cd” (do not type the quotes) 3. Type “git clone https://github.com/openhardwarecoza/LaserWeb.git” (do not type the quotes) 4. Type “cd LaserWeb” (do not type the quotes) 5. Type “npm install” (do not type the quotes)
The problem comes from following Windows default locations (C:\users…) for the install.
Install it to C:\laserweb
Then don’t forget step 5 (npm install).
The user directory and its subfolders aren’t in the path so the Node app can’t find the files it needs.
That’s what fixed it for me.
@Alex_Krause LW1 runs locally with a JS server. LW2 is hosted on http://github.io
+Peter van der Walt the npm install was the step I forgot. Also in Win 10 the users directory is not part of the path to find programs/executables/resource files. You have to explicitly add it.
Thanks guys, obviously the part of the problem was the path, I’ve reinstalled it to C:\laserweb
I did not forget “npm install”, but after that I’ve got a bunch of errors, and now I do get an interface in Chrome, but with an error, it says: "CRITICAL ERROR:
Laserweb may not work on this computer!
Try another computer with WebGL support
Try the following:
In the Chrome address bar, type: chrome://flags [Enter]
Enable the Override software Rendering
Restart Chrome and try again
Sorry! 
I tried that but to no avail.
I don’t know how to add images to this post, if someone can help, I have the screenshots of both the CMD and Chrome.
Thanks for your suggestions.
U can use http://imgur.com to post images.
try this to test webgl http://madebyevan.com/webgl-water/
O correct. Forgot about that.
OK, here are the screenshots, hope this link is enough?
I’m not at home at the moment, so I’m using the PC at my holiday house, not exactly antique, but not the latest hi-tech pearl either, so probably it lacks some features needed for LaserWeb to work…
I guess I’ll have to try this again when I get back home, don’t have any graphic card laying around.
So Peter, your recommendation is to use LW1 unless in case I use it with GRBL?
Thanks
I too had the WebGL issue on an old Dell. Had to add a newer graphics card and the error went away. I did a hardware check before and it stated that the machine supported WebGL2 but the browser did not like it. Updated drivers ect. Still did not work. IE would start without the error but then had other issues that I am sure was part of the WebGL problem. New Graphics Card = no more problems.
I did not make any significant mods to my K40 laser so far, but I’m considering different options. If I do decide to change the controller, I’m leaning against the smoothie board, so I wanted to check LaserWeb’s interface and features, to get a better insight about what I can expect from this combination during the couple of days off I took. Guess it’ll have to wait until I get back home;)
If I was at home the PC wouldn’t be a problem, as I have more than enough at home, but the only one I have here is just something I’d thrown together to have a machine for emails etc., not for serious work.
MB is HP 0A58H, CPU Intel Core 2 Duo E6300, 4 gigs of DDR2 , the onboard graphics Intel Q965/Q963 Express. I’ve only installed WIN 10 a month or so ago, so the drivers are as “new” as I could find…
I’m also checking Chromium, but as far as I can see, there’s only x86 version, and this machine runs x64 windows. I’m not exactly a programming guru, but I’ll try to find some solution…
@Mishko_Mishko I have run x86 software on a x64 before. Try it. Also i don’t belive you pc is that bad. What’s the current workflow you use? Smoothie runs very good on LW1 and will sure run on LW2
Thanks Ariel, will try Chromium x86. I’ve just tried Chrome Canary, but that doesn’t change anything.
This PC is not a pearl, but all the software I need runs just fine, Corel X7, Photoshop CS6, Inventor 2016, Vectric Aspire, Artcam and a bunch of others. I’ve never even heard about WebGL until today, maybe there’s a solution for that one, too, don’t know…
I use CorelLaser with Corel X7. At first it looked totally unusable to me, but once I got used to quite a number of stupidities and less than comprehensive interface, I’d say that, end of the day, it does the job. Of course, it leaves much to be desired, that’s why I wanted to check other software options.
I’ve worked on the Trumph laser for several years, using their older TOPS100 application, but I doubt any of the applications available on the net can compare with it, I’m not even sure that would make much sense for small machines like K14. It had a separate modules for drawing, nesting and technology, with material tables etc…
+Mishko Mishko by the software you run it’s weird that webgl it’s not supported. Do you have it enabled in the browser? http://superuser.com/questions/836832/how-can-i-enable-webgl-in-my-browser
FYI I just had this same problem and this fixed mine as well (running Wind10) thanks for the help.
+Peter van der Walt The one I used, TOPS100, is pretty old and almost DOS-like, Trumph has much more sophisticated (and complicated) applications now, but the old one was easy to use, to the point I still use its drawing module for creating DXF files;) If you want to give it a run, contact me by mail.
@Ariel_Yahni_UniKpty And all the applications run reasonably fast, maybe a tad slower than on my other machines, obviously WebGL is not required for any of them…
I’ve just downloaded chromium x86, but I have to find out how to install it first, windows installers are just about the extent of my expertise LOL
I’ve tried everything on that link, doesn’t help I’m afraid.
Will report about Chromium if I manage to install it…
@donkjr Was your problem just a path then, not WebGL?
