I start to plan the ZelosLaser Engraver with the goal of a well-built, Open Soft and Hardware Machine.The ZelosLaser Engraver is affordable, with a compact design and the perfect entry for the Daily Hobbyist.
It is easy to build. even for the non Hobbyist.
Please never forget that the laser can cause serious damage to your eyes. always wear safety glasses. Avoid to look directly into the beam.

Lets Engrave : ZelosDynamics Logo on Plywood
The Open Source ZelosLaser Engraver is a full working unit to engrave
and even cut material like plastics, wood, leather and much more. It is easy to build and has a number of exclusive features that cannot be found on other engraver machines.

Step 2: TOOLS
Tools you need
- Allen Key M4
a brush or something similar
Metalsaw when the steel rods or aluminum profiles are not even cut when you buy it.
Jigsaw when the base plate has not been cut when buying
some wood glue (to glue a thin layer of cork on the bottom plate)
Step 3: BUILD IT
Begin with the aluminum profiles. screwed all together like in the Images.
Do not forget to push enogh M4 threaded plates into the V-slot of the profile.
Step 4: Baseplate
glue the cork to the bottom plate as in the photos.
use a brush or similar to remove all the small blisters.
Turn around the bottom plate and put some weight on it.
Wait until the glue is dry.
Step 5: Attach the Handholds and Baseplate to the Frame
Attach the handholds with 4x - M4x20 screws.
Attach the Base Plate with the printed Holders.
Step 6: Prepare the Axis
Sliding/push the LM8UU linear bearings on the Steel Rods.
Attach the steel rods to the chassis.
fix the carriage to the linear bearings with cable ties.
Step 7: Electronics/wiring
Wiring Diagram for 2watt Laser
For the wiring we use a very reinforced system.
it is very easy to build and works great.
-If you want to use two motors with two Stepper Driver for Y axis, you can "clone" any axis for use two motors and two drivers for a single axis. The CNC shield is capable of it
Don´t connect the laser before adjust the power on the laser driver.
Step 8: SOFTWARE
Before you can start you need the Arduino IDE, available on their webpage.
Modified firmware for the Arduino UNO R3 or similar clone:
(Modified for Version 2.0 ZelosLaser Cutter with 2 Axis/3 Motors)
Grbl wiki: github.com/grbl/grbl/wiki
drawing software: Inkscape 0.91/combined with a laser engraver plug-in.
( we use @now the Plugin from the Microsclice Engraver. We are working on our own plugin)
Grbl needs G-Code.
We need another Program to send the G-Code to the Arduino UNO R3 board.
NOTE: Before starting, make sure that any older installation of Grbl has been completely removed from the Arduino IDE.
Download the Modified Grbl source code (v0.9i)
Once downloaded, unzip it and you'll have a folder called grbl-master or something similar.
Make sure you are using the most recent version of the Arduino IDE (last tested on v1.61).
Load Grbl into the Arduino IDE as a Library.
- Launch the Arduino IDE.
- Click the Sketch drop-down menu, navigate to Include Library, and click Add .ZIP Library, note that this still works with a folder (prior to IDE version 1.6.2 this will be Import Library..., and click Add Library...).
- Select the Grbl folder inside the grbl-master folder when asked to select a library folder you'd like to add. The correct folder only contains the source files and an example directory.It may take a few seconds for the Arduino IDE to import it.
NOTE: For pre-v1.05 Arduino IDE users, you will need to manually add Grbl into your Arduino libraries, so that it will appear in the Import Library... menu. Search the internet for how to install, then skip to step 4.
- Open the GrblUpload Arduino example.
- Click the File down-down menu, navigate to Examples->Grbl, and select GrblUpload.
- Compile and upload Grbl to your Arduino.
- Connect your Arduino Uno to your computer.
- Make sure your board is set to the Arduino Uno in the Tool->Board menu and the serial port is selected correctly in Tool->Serial Port.
- Click the Upload, and Grbl should compile and flash to your Arduino! (Flashing with a programmer also works by using the Upload Using Programmer menu command.)
Once you have your Grbl library set up in the Arduino IDE, you can update, replace, or modify the Grbl source code in the library folder. On a Mac, it's located in ~/Documents/Arduino/libraries/. On Windows, it's in My Documents\Arduino\libraries.
You may need to restart the Arduino IDE for this change to take effect.
No fuss! No muss!
