The PCB Milling Process

To mill PCBs effectively with the CNC 3018, you need to follow a detailed process that involves setting up the machine correctly, choosing the right bits for isolation routing, and generating tool paths to export the G-code for milling. Here's an overview of the key steps:

1. Design Verification: Ensure that your PCB design is accurate and optimized for milling.

2. Machine Calibration: Properly calibrate the CNC 3018 to ensure precise movements and accurate milling.

3. Bit Selection: Choose the appropriate bit for isolation routing based on your requirements and budget.

4. Tool Path Generation: Utilize software tools or Python scripts to generate tool paths and export the G-code for your PCB design.

5. Milling Process: Load the G-code into the CNC 3018 and carefully monitor the milling process.

Bit Options for Isolation Routing

When it comes to selecting the right bit for isolation routing on the CNC 3018, there are several options to consider:

Bit ——————–TypeDescription

20° V Bits (Bundled) Produce fine traces but require slower cutting and shallow depths.
30° V Bits More robust but result in wider tracks when cutting deeper.
20° V Bits with Flutes More forgiving in terms of cutting speeds and depths, but have a minimum track width of around 0.4mm.
Isolation Routing Bits Designed specifically for isolation routing, providing the best results but at a higher cost.

Achieving Success with the CNC 3018

Milling PCBs on a budget-friendly CNC machine like the CNC 3018 is a feasible process that requires attention to detail in setup, tool selection, and following the correct procedures for generating tool paths and exporting G-code. While it may have some limitations compared to industrial-grade machines, the CNC 3018 can be a reliable and cost-effective solution for hobbyists, makers, and small businesses looking to produce high-quality PCBs in-house.

By investing time and effort into mastering the PCB milling process on the CNC 3018, you can unlock a world of possibilities for prototyping, small-scale production, and exploring the exciting realm of electronics and circuit design.
