#LASER FOR ENGRAVING DOWNLOAD#
You can find and download this 3D model, as well as explore it in your browser on Thangs:ĭownload the assembly 3D model from Thangs: I made the holder for the laser in a way that the laser beam will be in the center of rotation of that 4 th axis, so even if the axis rotates it won’t affect the final position. The 4 th joint which rotates the end effector won’t be used, although the laser module will be attached on it. The robot has 4 degrees of freedom, but in this case, we only need 3 DOF, two rotations for reaching any point in the work area and one linear motion for adjusting the height of the laser. The joints are driven by NEMA 17 stepper motors which speed is reduced with the help of GT2 belts and some suitable 3D printed GT2 pulleys. The robot is designed in a way that most of the parts can be easily 3D printed. Here’s a quick look at the 3D model of this SCARA robot so you can see how it works in case you haven’t watched the original tutorial where I explain in details how I built it.
#LASER FOR ENGRAVING HOW TO#
We will take a look at the design of this SCARA robot, how to install and configure the Marlin firmware according to our machine, and how to prepare the drawings and the G-codes for engraving. Nevertheless, now I will walk you through the entire process of setting up a SCARA robot to work as a laser engraver. We can generate G-codes with contours only or with contours and infill from the same vector image, and we have various options like adjusting the laser beam, travel speed, infill speed, perimeter speed, laser on and off commands including PWM control of the laser and so on. We can do that thanks to the open-source Marling 3D printer firmware which has options for laser engraving and SCARA robot setup.įor generating the G-codes I’m using yet another open-source software, Inkscape and a plugin for it called Inkscape-Lasertools. We can actually set it up to use almost the entire 360 degrees around the robot as a working area. It can use the area in front of it as well as on both sides. In this case, I’m using 5.5W laser module which is good enough for engraving.Ī cool feature that we get with this SCARA robot setup is that we can have a bigger range of the Z-axis movement and so we can laser engraver taller objects.Īlso, the working area is pretty impressive considering the small footprint of the robot. We need this combination because we will use the Marlin 3D Printer firmware for controlling the robot.Īs for the mechanical part, I just had to change the gripper mechanism with a laser module.

In the original video I used an Arduino UNO board in combination with a CNC Shield, but now we will use an Arduino MEGA board in combination with a RAMPs board. The SCARA robot has 4 degrees of freedom which are driven by 4 NEMA 17 stepper motors and controlled using an Arduino board. You can watch the video following video or read the article below.

In this tutorial I will show you how I converted my DIY 3D Printed SCARA robot arm that I built in one of my previous videos to work as a laser engraver.
