makeCNC Workshop – Kerf Wizard App

Dial-In Perfect Laser Fits Every Time

 

comes with windows installer  mac version coming soon

The makeCNC Workshop Kerf Wizard is a practical, workshop-focused app designed to solve one of the most frustrating problems in laser cutting: getting perfect slot-and-tab fitment.

Instead of guessing, trial-and-error, or wasting material, Kerf Wizard gives you a repeatable, step-by-step workflow to measure kerf, choose the fit you want, and calculate exactly how your design should be cut.

It’s built for real laser users — beginners and pros alike.

🔥 Why Kerf Matters (and Why Guessing Fails)

Every laser removes material as it cuts. That cut width — kerf — changes with:

• Material type

• Material thickness

• Laser power & speed

• Focus, air assist, lens

• Even humidity

If you cut boxes, 3D puzzles, press-fit parts, or assemblies, kerf is the difference between:

• ✅ A clean press-fit build

• ❌ Loose, wobbly joints

• ❌ Cracked parts from being too tight

Kerf Wizard removes the guesswork and replaces it with measured results .

🧠 What the Kerf Wizard Does

The app guides you through a simple, proven process:

1️⃣ Machine & Material Profiles

Create reusable profiles for:

• Your laser

• Your material

• Your thickness

Profiles can be saved and reloaded, so once you dial something in, you don’t start from scratch next time .

---

2️⃣ Kerf Test Planner (No Math Required)

The app automatically generates a kerf test table — a set of slot widths you cut once as a small test strip.

You:

• Cut the test

• Pick the slot that feels right

• Enter the slot number

The app handles the math .

---

3️⃣ Kerf & Fitment Calculator

Based on your test result, the wizard calculates:

• Kerf per side

• Correct slot width

• Global scale percentage to apply to your design

You can choose your fit style:

• Tight (press-fit)

• Normal

• Loose (paint or easy assembly)

The results can be applied directly in your CAM software or in the makeCNC Scale Wizard .

---

🔧 Built for Real Workshop Use

• Works in mm or inches

• Runs locally in your browser

• Dark / Light mode

• Built-in help button opens the full user guide

• Designed to be clear even if you’re new to lasers

This isn’t machine-specific “magic numbers” — it’s a reliable workflow you can reuse any time your settings change .
