#Core Product Principle

Kerfio Laser should not only load an image. It should help the user convert that image into the correct laser job.

The main idea:

Import image
→ Clean and optimize image
→ Choose job type
→ Preview laser result
→ Generate laser-ready G-code
→ Send or export

The user should not need to understand every technical detail first. Kerfio should provide simple guided modes but also advanced controls for professional users.

#Main User Workflows

#Kerfio Internal Laser Project Format

Recommended internal file:

.kerfio-laser

This should be a project container, not just one flat file.

Example structure:

project.kerfio-laser
  /project.json
  /assets/original-image.png
  /assets/processed-image.png
  /assets/vector-trace.svg
  /toolpaths/engrave.gcode
  /toolpaths/cut.gcode

  /profiles/material.json
  /preview/bed-preview.png
  /logs/generation-log.txt

This allows the user to reopen the project later and continue editing.

#Image Import Dialog Structure

Kerfio should provide a modern image import wizard.

Recommended wizard steps:

Step 1: Import Image
Step 2: Set Physical Size and Position
Step 3: Clean and Optimize Image
Step 4: Choose Laser Mode
Step 5: Choose Material and Settings
Step 6: Preview Result
Step 7: Generate G-code / Send to Machine

The user should also be able to switch to advanced mode.

#Image Placement and Physical Size

A laser job must map pixels to real machine dimensions.

Kerfio should allow:

• Set width in mm
• Set height in mm
• Lock aspect ratio
• Set DPI
• Set line interval
• Set mm per pixel
• Move on bed
• Center on bed
• Align left/right/top/bottom
• Rotate
• Flip horizontal
• Flip vertical
• Crop
• Fit to work area

#Pixel-to-Machine Mapping

Example:

Image size: 1000 × 1000 px

Preview should show:

• Machine bed size
• Work origin
• Image position
• Image size
• Job bounding box
• Safe margin
• Travel path area
• Warning if outside machine area

#Image Optimization Tool

Kerfio should include a dedicated tool called:

Laser Image Optimizer

This tool prepares imported images for engraving or cutting.

The user should be able to quickly convert a bad image into a good laser-ready image.

#Basic Image Correction

Required tools:

• Brightness
• Contrast
• Gamma
• Exposure
• Saturation
• Convert to grayscale
• Invert image
• Sharpen
• Blur
• Crop
• Resize
• Rotate
• Flip

#Advanced Image Cleanup

Recommended tools:

• Auto contrast
• Histogram levels
• Black point adjustment
• White point adjustment
• Curves
• Noise reduction
• Despeckle
• Remove small dots
• Smooth edges
• Remove background
• Replace transparent background
• Convert transparent areas to white
• Convert transparent areas to ignore/cutout

#Laser-Specific Optimization

Laser-specific image tools:

• Material response curve
• Burn compensation
• Power curve preview
• Dot correction
• Minimum burn threshold
• Maximum burn threshold
• Highlight protection
• Shadow boost
• Edge enhancement
• Dither preview
• Engraving simulation preview

#One-Click Presets

Kerfio should include one-click presets:

• Photo on wood

Each preset should automatically adjust:

• Image mode
• Contrast/gamma
• Dithering or grayscale mode
• Speed/power suggestion
• Line interval
• Output strategy

#Laser Conversion Modes

Kerfio must support several conversion modes.

#Line-to-Line Grayscale Engraving

This mode is similar to LaserGRBL line-to-line engraving.

The laser scans the image line by line. Pixel brightness controls laser power.

#Use Case

Best for grayscale photos on materials that respond well to variable laser power.

#Required Options

• Direction: horizontal or vertical
• Scan mode: unidirectional or bidirectional
• Line interval
• DPI
• Minimum power
• Maximum power
• Feed rate/speed
• Overscan
• Gamma
• Invert
• Dynamic laser mode
• Constant laser mode

#G-code Behavior

For GRBL/FluidNC laser mode:

G21
G90
M4 S0
G0 X0 Y0
G1 X50 F3000 S700
G0 X0 Y0.1
G1 X50 F3000 S650
M5

Important:

• S value controls laser power.
• M4 dynamic power is preferred where supported.
• M3 constant power may be used for some workflows.
• M5 must turn laser off at the end.

#1-bit Black and White Engraving

This mode converts image to pure black and white.

#Use Case

Best for:

• Logos
• Icons
• Text
• QR codes
• Stamps
• Technical markings

#Required Options

• Threshold slider
• Adaptive threshold
• Invert black/white
• Remove tiny pixels
• Smooth result
• Preview black/white map
• Output as raster fill
• Output as vector trace

#Dithering Engraving

Dithering converts grayscale into dot patterns.

This is critical because many laser materials do not create true smooth grayscale. They may burn only as light/dark marks. Dithering simulates gray tones using small black dots.

#Required Dithering Algorithms

Kerfio should support:

• Floyd–Steinberg
• Atkinson
• Jarvis–Judice–Ninke
• Stucki
• Sierra
• Burkes
• Ordered dithering / Bayer matrix
• Halftone dots

#Required Options

• Dithering method
• Dot density
• Dot size
• Threshold strength
• Invert
• Preview at final physical size
• Material preset
• Line interval

#Best Use Cases

• Photo engraving on wood
• Photo engraving on leather
• Cardboard engraving
• Paper engraving
• Materials that do not respond linearly to laser power

#Vectorization / Trace Mode

Vectorization converts raster image to vector paths.

This is essential for creating cut paths from logos, drawings, and black/white images.

#Required Trace Types

• Outline tracing
• Centerline tracing
• Edge tracing
• Contour tracing
• Black region tracing
• External outline only
• Internal holes detection

#Required Options

• Threshold
• Turd size / small object removal
• Smooth corners
• Optimize path
• Simplify path
• Curve fitting
• Keep holes
• Remove holes
• Join nearby paths
• Close open paths

• Offset path
• Kerf compensation

#Recommended Backend

• Potrace for bitmap-to-vector tracing
• OpenCV for preprocessing
• Scikit-image for contour extraction
• Shapely for geometry operations
• svgpathtools for SVG paths

#Edge Engraving Mode

This mode extracts edges and engraves them.

Useful for:

• Sketch-like engraving
• Technical outlines

Algorithms:

• Canny edge detection
• Sobel
• Laplacian

Options:

• Edge strength
• Edge thickness
• Noise reduction
• Smooth edge
• Convert to raster or vector

#Cut Outline Mode

This mode creates a cutting path from an imported image.

Use cases:

• Cut around logo
• Cut around photo label
• Sticker-like cuts
• Acrylic signs
• Wooden tags

Options:

• Detect outer boundary
• Keep internal holes
• Ignore internal holes
• Offset outside
• Offset inside
• Kerf compensation
• Smooth outline
• Add tabs/bridges
• Multiple passes
• Cut order

#Mixed Raster + Vector Mode

This mode combines engraving and cutting in one job.

Example:

Raster engrave photo
→ Vector cut outside border
→ Optional score text

Layer order example:

1. Engrave image
2. Score details
3. Cut outline

This is important for real laser workflows.

• Cut
• Mark
• Trace
• Ignore

#Color-Based Mapping

Kerfio should support mapping colors to laser operations.

Example:

Black = engrave
Red = cut
Blue = score
Green = mark

This is very important when importing SVG/DXF designs.

#Image-to-Laser File Creation

Kerfio should create a proper laser job file from the imported image.

#Internal Job Output

The internal job should include:

• Source image
• Processed image
• Vector trace if any
• Physical size
• Position
• Machine profile
• Material profile
• Layer settings
• Processing mode
• Generated G-code
• Preview image
• Safety warnings

#Exportable Output Files

• Processed PNG
• Processed BMP
• SVG trace
• DXF trace
• G-code .gcode
• G-code .nc
• Kerfio laser job .kerfio-laser
• PDF preview/report optional

#G-code Generation Strategy

Kerfio should generate firmware-aware G-code.

#Supported Firmware Targets

MVP targets:

• GRBL
• FluidNC
• Marlin laser mode

Later:

• Smoothieware
• RepRapFirmware

#Required G-code Features

• Absolute/relative mode control
• Millimeter mode
• Laser on/off
• Power modulation with S values
• Feedrate handling
• Raster scan generation
• Vector path generation
• Safe travel moves
• Layer order
• End commands

#Common Commands

G21 ; millimeters
G90 ; absolute positioning
M4 S0 ; dynamic laser mode if supported
G0 X0 Y0
G1 X50 F3000 S700
M5 ; laser off

#M3 vs M4

Kerfio should explain:

• M3 = constant laser power
• M4 = dynamic laser power where supported

For GRBL laser mode, M4 is often preferred for engraving because power can adjust with motion dynamics.

#S-min and S-max

Kerfio should support:

• S-min
• S-max
• Power scale 0–255
• Power scale 0–1000
• Power scale 0–10000
• Percent to S conversion

Example:

User sets 70% power
Machine scale = 1000
Kerfio outputs S700

#Raster G-code Generation

Raster mode converts pixels into scan lines.

#Raster Strategy

Process:

1. Convert image to target resolution.
2. Convert pixels to grayscale/BW/dithered output.
3. Generate scan lines.
4. Compress consecutive pixels where possible.
5. Generate motion commands with proper S values.
6. Add overscan.
7. Add laser-off travel moves.

#Optimization

Kerfio should optimize raster G-code by:

• Skipping blank lines
• Skipping white areas
• Grouping same-power segments
• Using bidirectional scanning if enabled
• Applying overscan only where needed
• Reducing unnecessary S changes

#Vector G-code Generation

Vector mode converts paths into cut/engrave moves.

Required:

• Import SVG/DXF paths
• Convert curves to line/arcs where needed
• Preserve arcs when possible
• Sort paths
• Apply cut order
• Apply kerf compensation
• Generate multiple passes
• Add lead-in/lead-out optional

Operations:

• Line engraving
• Score
• Cut
• Outline cut
• Internal cut

#Cut Path From Image

This is one of the most important features.

The user imports an image, and Kerfio generates a cuttable outline.

#Workflow

Import image
→ Remove background
→ Convert to black/white
→ Detect boundary
→ Smooth path
→ Offset path
→ Assign cut settings
→ Preview cut
→ Generate G-code

#Required Controls

• Threshold
• Background removal
• External outline only
• Include internal holes
• Smooth path
• Simplify path
• Offset value
• Kerf value
• Add tabs
• Cut passes

#Burn Simulation Preview

Kerfio should include a simulated preview of final engraving.

It does not need to be physically perfect, but it should show:

• Darker/lighter areas
• Dither pattern
• Cut lines
• Engraving area
• Expected visual result

Preview modes:

• White material preview
• Wood material preview
• Black acrylic preview
• Metal mark preview

#Safety and Validation

Before sending the job, Kerfio should validate:

• Job fits inside bed
• Laser power is not zero
• Speed is not zero
• Laser turns off at end
• Homing status if required
• File has safe header/footer
• No unexpected Z move unless enabled
• Air assist warning for cutting
• Multiple passes warning
• Estimated time warning
• Machine connection active

Warnings:

The job is outside the machine work area.
The laser power is very high for engraving.
The image resolution is too high and may create a very large G-code file.
This material may not support grayscale engraving. Try dithering.

• 1-bit threshold
• Floyd–Steinberg dithering
• Basic vector tracing with Potrace
• Physical size control
• Speed/power settings
• S-min/S-max
• GRBL/FluidNC G-code export
• Basic toolpath preview
• Send to machine

#Phase 2 — Professional Workflow

Features:

• Multiple dithering algorithms
• Advanced image optimizer
• Material profiles
• Burn simulation
• SVG/DXF import
• Layer-based workflow
• Color-to-operation mapping
• Cut outline from image
• Centerline tracing

• AI image optimization assistant
• Material test grid generator
• Auto power/speed recommendation
• Rotary engraving
• Batch engraving
• QR/barcode generation
• Serial number engraving
• Multi-pass cut planner
• Job history and repeat jobs

#Material Test Grid Tool

Kerfio should include a tool to generate test grids.

This is extremely useful for laser users.

The user selects:

• Material
• Power range
• Speed range
• Step count
• Test type:
  • Engraving grid
  • Cutting grid
  • Photo engraving test

Kerfio generates G-code with labeled test squares.

This helps the user find the best speed/power combination.

#AI Assistant for Image Preparation

Later, Kerfio can include an AI-guided image assistant.

The assistant could suggest:

• Use dithering instead of grayscale
• Increase contrast
• Remove background
• Use vector trace for logo
• Use lower DPI for faster engraving
• Add outline cut
• Reduce power for leather
• Use test grid first

This should not replace manual controls. It should guide the user.

#Final Recommended User Experience

The ideal Kerfio Laser image workflow:

1. Import image
2. Kerfio detects image type
3. Kerfio asks: Photo, Logo, Cut Shape, Drawing, Mixed Job?
4. Kerfio applies recommended optimization
5. User adjusts preview sliders interactively
6. User selects material and machine
7. Kerfio shows burn/toolpath preview
8. User clicks Generate G-code
9. User frames the job
10. User starts engraving/cutting

This experience is much easier than a purely technical dialog.

#Final Recommendation

Kerfio Laser should include a complete image-to-laser system.

It should match the important LaserGRBL-style workflows:

• Raster image import
• Grayscale line-to-line engraving
• 1-bit black and white conversion
• Dithering engraving
• Vectorization
• Target size and laser power settings
• G-code preview and sending

But Kerfio should go further by adding:

• Interactive image optimizer
• Guided workflow
• Modern material profiles
• Burn simulation
• Layer-based operation control
• Image-to-cut-path workflow
• Better project file handling
• Integration with Kerfio CAD and CNC sections

The result should be a laser module where a user can import almost any image, improve it visually, convert it to engraving/cutting paths, preview the machine result, and generate a clean laser-ready file with confidence.
