Introducing Kurvengefahr
Kurvengefahr is an integrated browser-based solution providing both CAD and CAM capabilities specifically tailored for pen plotters.
Kurvengefahr — pen-plotter CAM
Core Functionality
The tool streamlines the workflow from design to physical output:
- CAD: Computer-Aided Design for creating vectors.
- CAM: Computer-Aided Manufacturing for generating plotter paths.
- Platform: Runs entirely within the
web browser.

Implementation Details
To move a pen, the system calculates coordinates, such as a simple curve defined by:
The resulting output is typically converted into G-code:
G0 X0 Y0 ; Move to start
G1 X10 Y10 F1000 ; Draw line
M5 ; Lift pen
