This was expensive both to develop and produce, and was even difficult to sell because of the final cost. In this case, why was this architecture chosen? If we go back in time, 10 or 15 years ago, there was great difficulty when building a micro controlled board. I have a PC> parallel port> controller card> drivers> stepper motors. I also suggest you use Protoneer and the assembly of the Laser Plotter performed in the first video on this subject.ġ - Mach3 = Example of a router that I have: The automation of these machines requires CNC control, so you can do many things by understanding this system.Ĭonsidering the image above, my personal suggestion is that you use Raspberry instead of the PC with Arduino Uno. These are all the same because the origin is the same. It is important to remember that when I talk about CNC (Computer Numeric Control), in addition to the laser plotter, I'm also talking about a router, a milling machine, and a CNC lathe. The feature is very efficient for the automation of CNCs. It has a 40W GPIO connector and supports the special auto configuration system, which allows for automatic configuration of the GPIO and driver configuration.

Today, we are going to talk about the HAT (Hardware attached at the top), which is a rectangular plate that has four mounting holes in the corners that align with the Raspberry Pi mounting holes. This gives continuity to the subject covered last week entitled, “Plotter and Laser with Raspberry Pi CNC HAT,” where we set up a laser plotter with an XY table. We’ll mount this HAT and configure the GRBL. We will prepare a Raspberry Pi 3 with the RPI CNC V4 image using HAT version 2.58. Today we’ll learn how to configure CNC with Raspberry Pi.
