Dial In Your CNC.
Without the Guesswork.

Stop burning bits and ruining material. CNC Manager walks you through finding the perfect feeds and speeds for any bit and material combination—no experience required.

The Old Way is Broken

Manufacturer specs are optimized for industrial machines—not your Shapeoko, X-Carve, or LongMill. The typical process looks like this:

  1. Look up "recommended" feeds and speeds
  2. Set up in VCarve/Fusion/Aspire
  3. Run the cut, something sounds wrong
  4. Tweak a parameter, regenerate G-code
  5. Repeat until you give up or get lucky

Sound familiar?

The CNC Manager Way

1
Tell us your setup

Machine, material, and bit. We suggest safe starting parameters.

2
Run the test cut

We generate the G-code. You just load and run it.

3
Score the results

Rate edge quality, chips, sound, and heat. Takes 30 seconds.

4
Get optimized parameters

We suggest adjustments. Repeat until dialed in.

Everything You Need. Nothing You Don't.

Guided Testing

Step-by-step wizard walks you through machine setup, material selection, and parameter adjustment. Learn the "why" as you go.

Auto G-code Generation

Skip the CAM software. We generate safe test patterns—star pockets, profiles, v-carves—ready to run on any machine.

Smart Diagnosis

Score your cut, and we analyze the results. Dusty chips? Increase feed. Chatter? Back off. We explain every recommendation.

Chipload Calculator

Real-time chipload indicator shows if you're in the sweet spot. Color-coded warnings prevent rubbing and tool breakage.

3D G-code Viewer

Visualize any G-code file before cutting. Click segments to inspect, add pauses, insert comments. Verify before you commit.

Export Results

Download your optimized parameters as text or JSON. Ready to paste into your CAM tool library.

Why Use CNC Manager?

Feature Manufacturer Specs Trial & Error CNC Manager
Machine-specific Industrial defaults Eventually From the start
Time to dial in Hours of testing Hours of testing Minutes
Requires CAM software Yes Yes No
Explains the "why" No No Yes
Cost Free (but generic) Broken bits + wasted material Free

G-code Viewer

Visualize, inspect, and verify any G-code file before it touches your machine. Works with files from VCarve, Fusion 360, Carbide Create, Aspire, and any CAM software.

  • 3D visualization with orbit controls
  • Click any segment to see the G-code line
  • Insert pause points (M0) or comments
  • Color by move type, depth, or feed rate
  • Animation playback with speed control
  • File statistics: runtime, distances, bounds
Open G-code Viewer

Drop any .nc, .gcode, or .tap file to visualize
