3dpBurner2 .STL files:

The 3dpBurner project has a lot of working hours, prototyping,  testings, burned electronics... I would like to recover some of the investment and thus to continue improving it. That is why i have decided to send the .STL files for printing after a donation. No matter the amount, you can donate any amount, i will be very grateful and you will be contributing with the project development.

Use the button below to make the donation, i will send you the .STL files to your Paypal email.

...However, if you don't can / want to make a donation for any reason contact me, i will send you files. If you like the project you can make a donation at any time. Thank you!!

-The recommended print settings are PLA at minimun of 3 perimeters, 40% infill.

Arduino Firmware
The firmware used by 3dpBurner is GRBL, an open source CNC motion controller. 

How to flash Arduino with the 3dpBurner firmware:

Easy flashing:
-Download laserGRBL application (free).

-Make sure you can connect to the machine, then disconnect.

-Go to "Tools" menu and "Flash Grbl Firmware".

-Select Arduino UNO as target and the latest GRBL version. NOTE: Make sure to select the XY Homing one if you has the endstops installed.

-Click OK and wait.

After finished, it is recommended to connect to machine and type $RST=* on the manual command text box and press Enter (this will wipe the GRBL EEPROM values).

Then connect to te machine go to "GRBL/GRBL Configuration" and import this configuration file, then press the Write button, this will set the standard 3dpBurner parameters into GRBL EEPROM.

NOTE: if you don´t use endstops you may prefer to dissable the homming function, set the $22 (Homing cycle enable) to 0 and click again the Write button.

Standard flashing:

Download the souce files, compile and flash using standard Arduino IDE. You can check the GRBL wiki flashing guide.

Speed Tips

*The bigger working area the lower acceleration (i use acceleration of 2000mm/min^2 on my A4 machine and 1000mm/sec^2 on my A3 one). Best acceleration is the maximun possible without producing perimeter pattern on grayscale image engravings.
*Too high acceleration. A thin edge but many vibrations and perimetral patterns
*Correct acceleration . A thicker edge but no vibrations/perimetral patterns

Control application


I recommend to use the free LaserGRBL control software, it is a simple and powerful application for Windows, it's open source and includes the standard controls plus many advanced features for image engravings.

You can download the latest version here.

I use CamBam as my main CAM program for vectorial works. These are useful files:
