Along with Fedora as my base operating system, the other pieces of open source software I used are GRBL, Inkscape, jscut, and CNCjs.ДЇor this tutorial, I'll explain how to create a CNC-milled, wooden version of Larry Ewing's Linux Tux logo. Instead, I'll focus on the open source software that can be used to create designs for and run the CNC machine. I won't go into details on the CNC hardware assembly, as Nikodem has a series of videos that explain it in detail. The GRBL website has documentation for loading GRBL onto the Arduino board. The machine has one stepper for the Z axis (up and down), one stepper for the X axis (left and right), and two steppers for the Y axis (backward and forward). The GRBL controller receives CNC G-code (a text-based list of instructions for the CNC mill) and translates it into motion by driving the stepper motors. The CNC machine is built on an Arduino controller running the open source GRBL motion-control software.

In the meantime, I 3D-printed the other parts. They shipped from overseas, so some of them took about a month to arrive. I ordered the necessary parts and started the wait. Its creator, Nikodem Bartnik, has a list of parts on the project's Thingiverse page along with links to download the 3D printed parts' STL files. While many of this CNC machine's components are 3D printed, several parts must be ordered to make it work. Unlike other milling tools, CNC machines can move on three axes: the Z axis moves vertically, the X axis moves horizontally, and the Y axis moves backward and forward. When I saw that the machine works with open source software and the controller is an Arduino running open source software, I knew I had to make one.Д¬NC milling machines are precision cutting tools used in creating dies, engravings, and models. When I recently saw a new design for a computer numeric code (CNC) milling machine that mostly uses 3D printed parts, I was intrigued. I'm always looking for new projects to create with my 3D printer. Watch videos, read documentation, check out the NYCNC channel, prepare for varying amounts of headaches, noise, and elation. Working knowledge of mechanical design, circuit theory, and a bit of mechatronics will greatly help the process. I'll be honest, if you're new to electronics and circuits in general, a CNC machine is a rewarding but ambitious project.

Each driver should have it's 'own' connection to the motor voltage and ground, in the sense that if one driver dies the others won't immediately lose their power connections.

To answer your question, yes all drivers must be connected to receive 5V pulses from the arduino, a constant high voltage connection from the power supply, and share a ground connection with both in a parallel relationship. Both drivers operate with the same pin input style though, so luckily the wiring logic is transferable. A larger driver will be more expensive and require manual creation of the power/signal/ground circuit, but will require less aggressive cooling and suffer less EM noise and save you a bunch of headaches down the line. Still, if you're a beginner, it's probably the best place to start.

That video is an A4988 driver, which cheap and works for small motors, but I found the current adjustment screw on it was finnicky and they tended to fail quickly. No worries - I remember starting with CNC and the hours spent learning this shit on my own.
