Introduction: Mini XY Laser Engraver

About: Makeblock was founded in 2012 as the world's first open-source robot and programing platform. With more than 400 mechanical components, electronic modules, and software tools, we are determined to bring meanin…

As one of the most practical kits in Makeblock platform, XY Plotter functions as a drawing robot in its initial form and a laser engraver after adding an add-on pack. Makeblock XY Plotter has been highly acclaimed in various exhibitions, such as Maker Faire. However, the size of XY means it's not a portable machine, especially for people who need to present it during every business trip. Hence we designed this mini XY laser engraver for portability.


Step 1: Working Principle

The hardware structure of XY Plotter is quite simple, one rectangular frame and linear guide controlled by two stepper motors being the main body. Thru the movement driving by the stepper motors, the laser head is able to locate any point within the working area with high accuracy of 0.1mm.

As for the software, it's composed of 2 parts, including PC client and embedded software. the PC client can be controlled by two software, Benbox and mDraw, both of which are capable of converting a photo to G-code that controls the movement of XY Engraver (those who participated in metalworking practice must be familiar with this). After a photo is converted to G-code, the software will transfer the G-code to the embedded software that will analyze the G-code, then control the position and power of the laser head via the stepper motor, and eventually achieve the goal of engraving.
