CNC Laser for Printing Images and Engraving. The Arduino Uno that shipped with my Shapeoko 2 kit came with grbl firmware version 0. This version of the firmware allows for M3M5 commands to enable or disable the signal on Pin 1. Arduino. It also provides support for Spindle Direction control. It does not however provide Spindle Speed control or any other type of signal we can use to control laser intensity. For this reason, I have modified the GRBL source code to allow the GShield to be put in Laser Mode. When the shield receives a L1 command, the Z axis motor is disengaged, and POSITIVE Z values from 0 to 2. A Z0 value sets the laser at its lowest current setting determined by calibration of the Flex. Mod P3 driver. A Z2. Amps if the Flex. Mod P3 was properly calibrated. From Z1 to Z2. 54 the power should gradually increase. To disable Laser Mode, and reengage the Z axis motor, send the L0 command to the GShield. This allows a GRBL program to enable and disable laser mode as needed. If you are so inclined, you can access my source code changes to the GRBL firmware in github at the following link https github. Laser. Mode. Be sure to select the Laser. Mode branch once you have cloned the tree. If you want to start with a pre compiled file recommended you can download the attached grbl. Once installed on the Arduino it should display version 0. There are many documented ways of installing the.

Leave the old one as a backup in case you have serious problems reprogramming the Uno with the new GRBL code. It should be possible to reprogram the Arduino Uno using its own USB port. I was unsuccessful in my attempt to do this from a Windows 8. PC however. The software froze up on me and left the Arduino in an unusable state. To fix this, I simply reprogrammed the Arduino using a USBtiny. ISP programmer from Adafruit.

If you do much work with Arduinos or AVR microcontrollers this is a must have tool You can also try using other USB based AVR programmers, from the one Sparkfun sells to the more expensive non hobby versions sold by ATMEL. You can go for pre built programmers as well, such as this one from Hobby King that is only 3. After downloading the grbl. ISP programmer to the Arduino Uno, and follow instructions on the programmer to upload the grbl. See the attached photos for details on how I did this with the USBtiny.

Sometimes it works fine for hours, sometimes it shuts. ISP programmer. To follow my process you will need to install the Arduino development software on your Windows PC. Dont worry, if you dont program you can take it off after we are done with this step. If there is enough demand, I could probably make a few pre programmed Unos available for purchase on e. Bay though I currently do not have plans to do this. From a cmd. exe prompt, locate the folder that contains the grbl. Then run the following commands.

Once you get the confirmation message avrdude done. Thank You, you can detach the ISP programmer and directly attach the Arduino Uno to your USB port. Then use your favorite GRBL controller software to connect to the Arduino. In the attached photos I am using a brand new Beta copy of Pic Sender. It was made by the author of Pic. Laser Lite from http www. We will use Pic. Laser Lite to send photos to the Shapeoko 2 to print or really burn grayscale images on various material. If you get to this before Pic. Sender is officially released you can use GRBL Controller 3. Intro step. You can also use the Universal GCode Sender. I will however warn you that the Universal GCode Sender should NOT be used with large GCode files, over about 1. Because it is a Java program and all Java programs are unfortunate, it has little control over how memory is used. After sending about 1. GShield, the Universal GCode Sender will slow down, causing the laser to burn your target material after the image has been printing for an hour or more. Hopefully fixes for this software will be available, though I am confident that the worst of the problems stem from the choice of language.
