slicer-slicer

this script is used to slice edges created from a slicer into smaller chunks. i use it for robotics, no idea what someone else could use it for.

!!! warning !!!

this is highly experimental. never let your printer run with gcode generated with this script without paying attention!

what it does

this was made in a hurry to achieve something for a very specific use case. for a robotics project i needed gcode, that has a high resolution for moves. so even straight moves needed to be split into smaller steps.

it will turn this:

G1 X0.1 Y20 Z0.3 F5000.0 ; Move to start position

into this:

G1 X0.005 Y0.952 Z1.919 F5000 ; - G1 X0.1 Y20 Z0.3 F5000.0 ; Move to start position 0/20

install

clone directory:

git clone https://github.com/max-hans/slicer-slicer.git

cd into this directory and run:

cd slicer-slicer
npm install

run

when in this directory run:

node src/index.js -p c:\path\to\your\file\yourgcode.gcode

dont forget replacing the path with the path to your code. usually dragging a file into the terminal works, too

options

--path / p

path to gcode file to work on (mandatory)

maxlength / l

maximum edge length. every edge longer than that will be sliced into segments

default: 1mm

accuracy

float accuary

default: 3 digits

inplace

will save new file next to the original file. if omitted, it will save the file in the output-folder of this project

default: save in output folder

platforms

this was tested on a win10 machine running node v12.10.0 and gcode created by Cura 4.7.1.

it only uses pretty standard modules, so it should work on other platforms as well.
