Bulk 3D Print Automation with OctoPrint API

This project automates batch 3D printing by generating dynamic G-code files and controlling OctoPrint-enabled printers via REST API. It supports configurable repeat printing, Z-axis offsets, and custom temperature settings for high-volume production.

Features

• Dynamic G-code generation with repeat logic and configurable offsets
• JSON-driven print configuration for temperature, copy count, and movement profiles
• OctoPrint REST API integration for remote print control
• Modular design using separate processors for config parsing and G-code assembly
• Command dispatch system for structured printhead movement

Configuration

Adjust values in config.json to suit your printer setup:

{ "bedTemp": "65", "fline": "0.1", "sline": "0.4", "nozzleTemp": "215", "lineheight": "2.3", "coolbedtemp": "30", "coolnozzzeltemp": "210", "babystep": "8", "copies": 3 }

How It Works

• The script generates repeated G-code segments using precode, mainobj, and postcode.
• It adds Z-height offset per iteration using lineheight + index * babystep.
• The final G-code is written to gcodes/main.gcode.
• Optional OctoPrint API commands allow you to start or cancel prints and send G-code directly.

Config.json Use

Example Usage

API_KEY = "YOUR_API_KEY" OCTOPRINT_URL = "http://your-printer-ip:5000" FILE_PATH = "auto.gcode" GCODE_COMMAND = "G28" # Home all axes

send_gcode(API_KEY, OCTOPRINT_URL, GCODE_COMMAND) start_print(API_KEY, OCTOPRINT_URL, FILE_PATH) stop_print(API_KEY, OCTOPRINT_URL)

Getting Started

Place your desired G-code object sequence into codeprocessor.py Set parameters in config.json Run the script: python main.py Generated G-code will be saved in gcodes/main.gcode

Future Enhancements

Add support for multiple printers Build a web-based dashboard for managing batches Integrate logging and real-time status feedback Queue management for continuous production
