== [[JSCut.org]] ==
{{Tipp|Tipps:
* If you're creating your own [[SVG]], make sure the pockets are "closed paths", meaning "areas", not open paths. Also use only infill, no stroke!
* Adding tabs with [[Inkscape]]:
** [[Inkscape add CNC tabs]]
}}
{{Info|1=[[JSCut]] is awesome, but has downsides:
* Can't create tabs (or won't work at the time of testing)
* Won't cut open-ended paths, only closed paths. Will close path if open with strange results
* [[jscut]] ignores stroke and follows the actual path not the visible dimensions (Say you (using [[Inkscape]])have a square 100x100mm and stroke 10mm, then [[jscut]] will cut 5/5 to 5/95 to 95/95 to 95/5! → Design in Inkscape W/O STROKE (only fill)!

Since JSCut isn't developed any more, try using it's successor: [[Laserweb]]
}}
* Create [[SVG]] with [[Inkscape]]
* Launch https://jscut.org/
* Open [[SVG]]
* Set units correctly (in my case <tt>mm</tt>)
* Set speeds and diameters, material strength and so on...
* Select object
* Generate operation
* Preview
* Repeat operation-generation for all your objects
* Download
* Hope for the best :)
=== Creating Tabs With [[JSCut]] ===
This is how it should work: https://www.youtube.com/watch?v=lwCatZ6q2Vw
Unfortunately this functionality seems to be broken on [http://jscut.org]&hellip;
cam-cpp.js is unavailable; tried the following paths:
js/cam-cpp.js
http://api.jscut.org/js/cam-cpp.js
on https://jscut.org
&hellip;I installed my own server:
* wget https://github.com/tbfleming/jscut/archive/refs/heads/gh-pages.zip
* unzip gh-pages.zip
* <del>wget https://github.com/tbfleming/web-cam-cpp/archive/refs/heads/master.zip</del>
noc:/srv/www/htdocs/jscut # make
cd cpp && em++ cam.cpp hspocket.cpp separateTabs.cpp vEngrave.cpp -I ../../boost_1_56_0 -std=c++11 --memory-init-file 0 -fcolor-diagnostics -Wall -Wextra -Wno-unused-function -Wno-unused-parameter -Wno-unused-variable -Wno-logical-op-parentheses -s
ASSERTIONS=0 -s ALLOW_MEMORY_GROWTH=1 -s SAFE_HEAP=0 -s DISABLE_EXCEPTION_CATCHING=1 -s FORCE_ALIGNED_MEMORY=1 -s NO_EXIT_RUNTIME=1 -s EXPORTED_FUNCTIONS="['_hspocket', '_separateTabs', '_vPocket']" -o ../js/cam-cpp.js  -O3 --llvm-lto 1
/bin/sh: line 1: em++: command not found
make: *** [Makefile:63: default] Error 127
noc:/srv/www/htdocs/jscut #
Ooookay...
wget https://github.com/emscripten-core/emsdk/archive/refs/heads/main.zip
unzip main.zip
cd emsdk-main/
./emsdk install latest
./emsdk activate latest
Adding this to .bash_profile:
  PATH=$PATH:/root/emsdk-main:/root/emsdk-main/upstream/emscripten:/root/emsdk-main/node/16.20.0_64bit/bin
  EMSDK=/root/emsdk-main
  EMSDK_NODE=/root/emsdk-main/node/16.20.0_64bit/bin/node
Which lead to...
em++: error: --memory-init-file is no longer supported
Then I removed the line from Makefile
em++: error: invalid command line setting `-sFORCE_ALIGNED_MEMORY=1`: forced aligned memory is not supported in fastcomp
Removed it, too.
./cam.h:22:10: fatal error: 'boost/polygon/polygon.hpp' file not found
Which lead to...
wget https://boostorg.jfrog.io/artifactory/main/release/1.84.0/source/boost_1_84_0.tar.gz
tar xzf boost_1_84_0.tar.gz
mv cpp/boost ../boost_1_56_0
THEN I IT COMPILED! UNBELIEVABLE! And no errors in UI!
But the created gcode seems to be b0rken, so this plan is out of the window.
It's 10 years old and its over. Whats the successor? ([[LaserWeb4]])
== [[LaserWeb4]] ==
[[Laserweb]] seems to be a very active project...<br/>
[[File:lasweb tabs clampksnip_2024-03-24_14-29-17.png|400px]]
* 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

Do:
* Make sure you played with [[Inkscape]]-[[SVG]]s and [[jsCut]] enough to understand the basics, otherwise handling (the much more complex [[FreeCAD]]) will be very frustrating…
* Launch [[FreeCAD]]
* Make sure you have already created proper solids (see above)!

Designing your product

Inkscape

In the 3D-world I prefer the simple OpenSCAD and in 2D it's the also fairly simple Inkscape which is free and awesome, too! ;)

  • Basic usage is pretty easy, just try it. If in doubt, there's plenty of manuals and tutorials online
  • Inkscape add CNC tabs


Creating GCODE

Overview

Tool Still maintained Ease of use Functionality Comment
JSCut.org no ***** ***--  Missing/broken tabs operation, otherwise great, especially for newbies!
LaserWeb4 yes ***** *****  Similar zu JSCut, can do tabs (add them as path to/as svg and then to the tabs of the operation), AppImage/Binary for the popular systems.
PyCAM no ? ?  Still needs python 2.7 and seems to abandoned since 2019.
Blender CAM ? ? ?  NOT TESTED YET! https://blendercam.com/
gcad3d ? ? ?  NOT TESTED YET! https://www.gcad3d.org/

What works fine for me:

  • UGS (on my old T60 w/o visualization, might be an issue with the old machine)
  • cncjs
