PlotFlow Engine™
The integrated workflow that maps creative inputs—text, SVGs, images—to printer-aware, pen-optimized G-code and matching hardware mounts.
Unlike DIY approaches that treat content, motion, and mechanics as separate hacks, PlotFlow Engine orchestrates all three layers into a reliable, repeatable system.
The 4-Layer Plotting Stack
Each layer is purpose-built for pen plotting—not adapted from 3D printing software.
Content Layer
Transform creative inputs into plottable vector paths
- 50+ Hershey stroke fonts optimized for single-line drawing
- Image vectorization with adjustable threshold and detail
- SVG import with path optimization
- Hatching and fill patterns tuned for pen plotting
- Text layout tools with kerning and spacing controls
Motion Layer
Generate safe, optimized movement commands for your specific printer
- Safe Z moves with configurable pen-up/pen-down heights
- Acceleration profiles tuned for pen plotting (not 3D printing)
- Coordinates adjusted for each printer bed geometry
- Travel path optimization to minimize pen-up movements
- Speed settings that prevent ink bleeding or skipping
Mechanics Layer
Physical pen holder design that ensures consistent results
- Pen holder STLs designed for specific printer models
- Spring-loaded designs for consistent pen pressure
- Repeatable pen position across multiple sessions
- Quick-release mounting for easy print/plot switching
- Tested with common pen diameters (8-12mm)
Integration Layer
Ties everything together with printer-specific profiles
- Pre-configured profiles for Bambu Lab, Prusa, Creality, Ender
- Custom Board for any bed dimensions
- Visual calibration wizard for fine-tuning
- Real-time preview on simulated printer bed
- One-click G-code export with correct headers/footers
Why PlotFlow Engine Works
It links three layers—content, motion, and mechanics—rather than treating them as separate hacks.
Eliminates Failure Modes
The closed-loop system prevents common issues: wobbly mounts, mis-scaled plots, bed crashes, and inconsistent line quality.
Printer-Profile Based
Improvements and new printer support benefit all users automatically—no need to reinvent the workflow for each printer.
No Manual Tweaking
Unlike DIY approaches, you don't need to manually calculate offsets, edit G-code, or debug scripts.

| Aspect | DIY Approach | PlotFlow Engine |
|---|---|---|
| Setup Time | 4-8 hours | <30 minutes |
| Tools Required | Inkscape + plugins + scripts + G-code editor | Just a web browser |
| Printer Support | Manual configuration per printer | Pre-configured profiles + Custom Board |
| Pen Holder | Find/design yourself | Tested STLs included |
| Calibration | Manual measurements | Visual wizard |
| Updates | Maintain yourself | Automatic improvements |
Technical Details
How PlotFlow Engine Generates G-code
- 1. Input Processing: Your design (text, image, or SVG) is converted to optimized vector paths. For text, we use Hershey fonts that draw each letter with a single stroke. For images, we apply vectorization with configurable detail levels.
- 2. Path Optimization: Paths are sorted to minimize pen-up travel distance. Connected paths are merged. The result is efficient plotting with minimal wasted movement.
- 3. Motion Planning: Based on your printer profile, we generate G-code with appropriate speeds, accelerations, and Z heights. Pen-up moves use safe heights; pen-down moves use calibrated contact heights.
- 4. Output Generation: The final G-code includes printer-specific headers, homing sequences, and end routines. It's ready to run—no manual editing needed.
