dcode: ImageNet-Sketch to G-code Dataset

A dataset of ImageNet-Sketch images paired with generated G-code for training text-to-gcode diffusion models.

Overview

This dataset enables training models that convert text descriptions directly into G-code for CNC machines, plotters, and polargraph drawing robots.

Feature	Value
Source Images	ImageNet-Sketch
Classes	1,000 ImageNet categories
Images	~50,000 black/white sketches
G-code Files	~200,000 (4 algorithms × images)
Algorithms	spiral, crosshatch, squares, trace

Algorithms

Algorithm	Description
spiral	Concentric spiral from center, density varies with brightness
crosshatch	Multi-angle hatching lines at configurable angles
squares	Concentric squares sized by local brightness
trace	Binary edge detection with scan-line tracing

Usage

from datasets import load_dataset

# Load the dataset
ds = load_dataset("twarner/dcode-imagenet-sketch")

# Access image and corresponding gcode
sample = ds["train"][0]
print(sample["image_path"])
print(sample["gcode_path"])
print(sample["caption"])  # "a sketch of a goldfish"

Training

This dataset was used to train dcode-sd-gcode-v3, an end-to-end text-to-gcode diffusion model.
