OctoClaw - Enhanced Octoprint Control Skill

You are now controlling an Octoprint 3D printer instance with advanced monitoring, analysis, and notification capabilities.

Helper Script Location

$SKILL_DIR/scripts/octoprint.py

Core Commands

Status & Monitoring

Get Formatted Status (Recommended for user display)

bash

python3 ~/.claude/skills/octoclaw/scripts/octoprint.py status-pretty

Shows beautifully formatted status with:

•Color-coded printer state
•Temperature readouts with status indicators
•Progress bar for active prints
•Time elapsed, remaining, and ETA
•Filament usage estimates

Get Raw Status JSON

bash

python3 ~/.claude/skills/octoclaw/scripts/octoprint.py status

Returns raw JSON for parsing.

Check for Errors

bash

python3 ~/.claude/skills/octoclaw/scripts/octoprint.py check-errors

Monitors for:

•Printer error states
•Temperature anomalies (deviation from target, overheating)
•Connection issues
•Stalled prints Returns JSON with errors/warnings array.

File Management

List Files

bash

python3 ~/.claude/skills/octoclaw/scripts/octoprint.py list-files

Upload File

bash

python3 ~/.claude/skills/octoclaw/scripts/octoprint.py upload <local-filepath> [remote-filename]

Analyze GCode

bash

python3 ~/.claude/skills/octoclaw/scripts/octoprint.py analyze <filepath>

Extracts metadata from gcode files:

•Layer count
•Estimated print time
•Filament length/volume
•Bed and hotend temperatures
•Bounding box dimensions

Print Control

Start Print

bash

python3 ~/.claude/skills/octoclaw/scripts/octoprint.py print <filename>

Control Print

bash

python3 ~/.claude/skills/octoclaw/scripts/octoprint.py control <pause|resume|cancel>

Set Temperature

bash

python3 ~/.claude/skills/octoclaw/scripts/octoprint.py temp <tool0|bed> <temperature>

Webcam Features

Capture Snapshot

bash

python3 ~/.claude/skills/octoclaw/scripts/octoprint.py snapshot [output-path]

Captures current webcam image. If no path provided, saves to /tmp with timestamp.

Telegram Integration

Send Status to Telegram

bash

python3 ~/.claude/skills/octoclaw/scripts/octoprint.py telegram-status

Sends formatted status message to configured Telegram chat.

Send Snapshot to Telegram

bash

python3 ~/.claude/skills/octoclaw/scripts/octoprint.py telegram-snapshot

Captures and sends webcam snapshot with progress caption to Telegram.

Send Custom Message

bash

python3 ~/.claude/skills/octoclaw/scripts/octoprint.py telegram-msg "Your message here"

Sends arbitrary message to Telegram (supports Markdown formatting).

Workflow Examples

Monitor Active Print

•Use status-pretty to show formatted status with progress
•Optionally capture snapshot to see current state
•Use check-errors to verify no issues
•Send snapshot to Telegram for remote monitoring

Start New Print

•Check printer state with status-pretty
•Ensure printer is Operational (not printing/error)
•List files or upload new gcode
•Optionally analyze gcode to show estimates
•Start print
•Send Telegram notification that print started

Troubleshoot Issues

•Run check-errors to identify problems
•Check temperatures are reaching target
•Verify printer connection status
•Capture snapshot to visually inspect
•Send diagnostic info to Telegram

Remote Monitoring

•Periodically send snapshots to Telegram
•Send status updates at milestones (25%, 50%, 75%)
•Alert on errors or completion
•Provide ETA estimates

Response Formatting

When showing status to users:

•Use status-pretty for terminal display (includes colors and formatting)
•Parse status JSON when you need programmatic access
•Always show progress percentage, time remaining, and ETA for active prints
•Include temperature info (actual/target)
•Mention filament usage if available

Telegram Setup

To enable Telegram features, the config.json must include:

•telegram_bot_token - Get from @BotFather on Telegram
•telegram_chat_id - Your chat ID with the bot

To create a bot:

•Message @BotFather on Telegram
•Send /newbot command
•Follow prompts to name your bot
•Copy the bot token to config.json

To get your chat ID:

•Message your bot
•Visit: https://api.telegram.org/bot<TOKEN>/getUpdates
•Find your chat ID in the response

Error Handling

The skill will automatically detect:

•Critical errors: Printer error state, connection lost, extreme temperature deviations (>15°C)
•Warnings: Moderate temperature deviations (5-15°C), potential stalled prints

When errors detected, recommend:

•Send error details to Telegram for immediate alert
•Capture snapshot to assess situation
•Pause print if temperature deviation detected
•Cancel print if critical error

Arguments

When invoked with arguments, use $ARGUMENTS to route commands:

•/octoclaw status → Show pretty formatted status
•/octoclaw check → Run error check
•/octoclaw snapshot → Capture and show snapshot path
•/octoclaw telegram → Send status to Telegram
•/octoclaw telegram snap → Send snapshot to Telegram
•/octoclaw print <file> → Start printing
•/octoclaw pause → Pause print
•/octoclaw resume → Resume print
•/octoclaw cancel → Cancel print
•/octoclaw analyze <file> → Analyze gcode file

If no arguments provided, show formatted status by default.

Best Practices

•Always check status before starting prints
•Use error monitoring during long prints - Periodically run check-errors
•Send Telegram notifications for important events - Print start/finish, errors
•Capture snapshots at milestones - Beginning, 50%, completion
•Analyze gcode before printing - Give users time estimates and filament requirements
•Format output appropriately - Use pretty status for humans, JSON for parsing
