🚀 Making Sure Your GCode Works Before You Cut

The last thing you want is to find out halfway through a cut that your file is junk. Here’s how to avoid that nightmare:

1. Visualize the Toolpath

Open your GCode file in software like CNC Simulator Pro or Camotics to preview the cut path.

• Check for Jumps and Gaps: Make sure your router doesn’t suddenly leap to a new position.
• Simulation Accuracy: Verify that the cut depths and speeds make sense.

2. Test on Scrap Material

Don’t risk your best stock on an untested file. A quick test cut will save you material and frustration.

3. Check Feed and Speed Settings

Even well-made GCode can be problematic if the feed rate is too high or the spindle speed is too low. Double-check and tweak as needed.

📝 Real-Life Scenario: Fixing GCode Woes

Picture this: You download a free GCode file from a random site, fire up your CNC router, and watch as the bit dives straight through the material like it’s on a mission to China. 😱

Here’s how to avoid that disaster:

1. Load the GCode in CNC Simulator Pro.
2. Analyze the toolpath for abrupt movements or errors.
3. Adjust feed rates directly in the GCode editor if necessary.
4. Run a dry test with your CNC router before cutting.
