Finally, let’s take a look how we can generate G-code from images with this GRBL-Plotter software. https://howtomechatronics.com/wp-content/uploads/2021/11/Generating-G-code-for-CNC-Drawing-machine-with-Automatic-Tool-Changer-1024x682.png?ezimgfmt=ng:webp/ngcb2 Once we load the image, we can click o...

What’s left to do now is to give life to it or make it a real CNC machine. For that purpose, we need to install a firmware to the Arduino for controlling the motion of the CNC machine and we need a control software through which we will send G-codes and tell the machine what to do. https://howtomech...

There few final touches that needs to be done in order to complete this pen plotter. Here I’m installing the pen gripper which is simply attached to the servo motor through the servo horn. https://howtomechatronics.com/wp-content/uploads/2021/11/installing-the-pen-gripper.jpg?ezimgfmt=ng:webp/ngcb2 ...

Here’s the circuit diagram of how everything needs to be connected. https://howtomechatronics.com/wp-content/uploads/2021/11/DIY-CNC-Pen-Plotter-Circuit-Diagram-1024x596.png?ezimgfmt=ng:webp/ngcb2 The components needed for this project: Stepper Motor – NEMA 17 Stepper Motor – NEMA 17 23mm A4988 Step...

With this the mechanical part of the machine is ready and we can move on with connecting the electronics. As I mentioned, we are using an Arduino Uno board in combination with a CNC shield and three A4988 stepper drivers. https://howtomechatronics.com/wp-content/uploads/2021/11/Arduino-Uno-based-CNC...

Here are all the parts needed for assembling the pen plotter. https://howtomechatronics.com/wp-content/uploads/2021/11/3D-printed-parts-mechanical-and-electronics-components-required-for-the-CNC-pen-plotter.jpg?ezimgfmt=ng:webp/ngcb2 Here’s a list of components needed for assembling this DIY CNC mac...

To begin with, let’s have a look at the design of this CNC machine. https://howtomechatronics.com/wp-content/uploads/2021/11/CNC-Pen-Plotter-3D-Model-1024x559.jpg?ezimgfmt=ngcb2/notWebP The two main components are the MGN15H linear rails, together with their suitable sliding blocks. The motion for t...

The construction of the machine uses 3 NEMA 17 stepper motors for the X, Y and the Z axis motion, and a small servo for the gripper. The brain of this CNC Pen plotter machine is an Arduino UNO board in combination with a CNC shield and three A4988 stepper drivers. https://howtomechatronics.com/wp-co...

In this tutorial by How To Mechatronics You will be shown how to built a CNC pen plotter or a drawing machine but with one cool feature and that’s automatic tool change. In other words, the machine will be able to automatically change colors and so you can draw really cool stuff with it.

Servo motors respond very quickly to position change commands. In t his project, this property is used to pull the puppet's strings and make it dance or move in any desired direction. https://ios.ru/forum/download/file.php?id=436&t=1 The control of the servo drives is based on step-by-step playb...
