Diptrace and CopperCAM: A Step-by-Step Guide for Converting Your PCB Schematics to G-Code

When working on a PCB project, one of the most crucial steps is converting your schematics into G-code that can be used by your CNC mill. In this tutorial, we will explore how to use Diptrace and CopperCAM to achieve this conversion. We will also discuss the importance of using the right software for your CNC milling needs.

The first step in our process is to set up the number of tools you plan to use. However, we will cover this topic under the export process later on. For now, let's focus on setting up our view and preparing our PCB layout for conversion.

To do this, go to the 'Top' view and select the 'Calculate isolating toolpaths' icon. This will allow us to create a 3D representation of our PCB layout. Next, select the number of extra contours that your engraving bit should run around the tracks. For this example, we will set Dx=-2.5 and Dy=-2.5.

Once you have set these parameters, click 'OK' to generate the 3D model of your PCB. You should now be able to see how your board will look like in its final form.

Next, select Layer 6 (Card Cutout) and go to 'Files' > 'Offset.' Here, you can load the Board Outline file 'BoardOutline.gbr' and click 'Yes' if it looks correct. You should also load the N/C Drill file 'Through.drl' and ensure that the drill holes are correctly placed.

Finally, select the Top Layer file 'Top.gbr' and go to 'Files' > 'Open' > 'Drills.' This will allow you to view your PCB layout in its final form.

Once you have completed these steps, it's time to start using CopperCAM. To do this, go to 'Files' > 'Open' > 'New Circuit.' Here, you can create a new circuit and import your Gerber files. CopperCAM is a great tool for creating G-code from your PCB schematics, and its user-friendly interface makes it easy to use.

If you're looking for an alternative to CopperCAM, you may want to consider using Mach 3 or LinuxCNC. These software options work well with CNC mills and can be used to create G-code from your PCB schematics.

In conclusion, converting your PCB schematics into G-code is a crucial step in any CNC milling project. By following the steps outlined above, you can use Diptrace and CopperCAM to achieve this conversion and ensure that your PCB layout is correctly prepared for milling.

For those who prefer a more visual approach, I have also included a video tutorial that walks you through each of these steps. Additionally, the image and text step-by-step guide on the next page provides further detail on how to use Diptrace and CopperCAM for your CNC milling needs.

Overall, I believe that both Diptrace and CopperCAM are excellent software options for creating G-code from your PCB schematics. Whether you're using Mach 3 or another software option, these tools can help you achieve professional-looking results with minimal effort.
