How to Use PCBMill

Using PCBMill is a straightforward process that can be broken down into several steps. Here's a step-by-step guide on how to use PCBMill:

Step 1: Generate a Gerber File

The first step in using PCBMill is to generate a Gerber file for your PCB design. This can be done using a PCB editor software such as Eagle or KiCad. Once you have generated your Gerber file, you can import it into PCBMill.

Step 2: Make Your Settings in the Setup Menu

Before you can start milling your PCB, you need to configure your milling parameters and settings. This can be done using the Setup menu in PCBMill. Here, you can configure your milling speed, feed rate, and other parameters.

Step 3: Open Your Gerber File in PCBMill

Once you have configured your settings, you can open your Gerber file in PCBMill. This can be done by selecting "File-> Open Gerber" from the menu.

Step 4: Calculation of Contour/Milling Path

Once you have opened your Gerber file, PCBMill will start calculating the contour/milling path. This process may take several minutes, depending on the size of your file.

Step 5: Error Checking

Once the contour/milling path has been calculated, you can check your design for errors and completeness. This can be done using the error checking feature in PCBMill.

Step 6: Generate G-Code for Milling

If you are happy with your design, you can generate G-code for milling by selecting "File-> Export-> Milling G-Code" from the menu. This will generate a G-code file that can be used to mill and drill your PCB on a CNC machine.

Benefits of Using PCBMill

Using PCBMill has several benefits, including:

Speed: PCBMill is a fast and efficient software that can generate milling paths quickly.
Accuracy: PCBMill is highly accurate, and can generate milling paths with high precision.
Ease of Use: PCBMill is easy to use, and has a user-friendly interface that makes it easy to configure your milling parameters and settings.
