LaserWeb4

About

https://github.com/LaserWeb/LaserWeb4-Binaries/releases

Laserweb seems to be a very active project...

• First impression
  • Much more powerful than jscut
  • JSCut does honor visibility flags of layers and paths. LaserWeb doesn't
  • I like the material/tool library
  • It can create tabs the way JSCut does/did/should (converting from drawn paths)
  • Great visualization of the cutting path

This shows the basic usage: https://www.youtube.com/watch?v=UCTDbdJotHY

FAQ

Open paths

I ran into an issue where LaserWeb kept ignoring paths while other worked just fine.

I tested this:

• Milling Pocket won't work
• Milling Cut would work
• Read https://github.com/LaserWeb/LaserWeb4/issues/456

How I solved this:

• Remove fill
• Add stroke (Hairline)
• Identify gap (Tipp: if two points are in the same location, they appear greyish)
• Close gap

It's that easy! Took me the better part of an hour to figure out…

Installation on OpenSUSE (as Webserver)

#1st Attempt (failed)

See: https://github.com/LaserWeb/LaserWeb4/wiki/1.3-Installation-on-Linux

zypper install npm
zypper in chromium
zypper in git
zypper in gcc-c++
cd /usr/local
git clone https://github.com/LaserWeb/lw.comm-server.git
cd lw.comm-server
npm install node-gyp
npm install @serialport/parser-readline
npm install -g npm-check-updates
npm-check-updates -u
npm install
npm audit fix
npm install

(unfinished)

const Readline = SerialPort.parsers.Readline;

#2nd Attempt (works like a charm)

See: https://github.com/LaserWeb/LaserWeb4

zypper install docker
systemctl enable docker
systemctl start docker
docker run -p 8000:8000 joesantos/laserweb:latest

(Maybe some use of firewall-cmd to adjust to the port)

Point your browser to the host's port 8000, that's it!

If you prefer https, I'd recommend using a reverse proxy and Letsencrypt.
