Open the Marlin.pde file contained within the Marlin source code in Arduino.Īt a minimum we recommend changing the STRING_VERSION_CONFIG_H and STRING_CONFIG_H_AUTHOR definitions in Configuration.h. Open the Arduino preferences and turn on the checkbox to enable verbose output during compilation. Launch your installed version of Arduino and choose Teensylu/Printrboard from the Tools Board menu.

ĭownload the pre-configured Arduino software from the link available at and copy it to your /Applications folder. See the following sections for more detailed instructions.ĭownload a pre-configured Arduino build environment that contains the compilers for the AT90USB1286 chip from. The source code used to build the factory-default firmware as well as checksum information for the provided hex files is available at Advanced users may wish to compile their own firmware either to adjust some configuration parameters or to experiment with new features. You can use the files above to restore to a factory-default state. Obtaining a firmware fileThe default firmware as shipped is archived at įor the Printrbot Junior ONLY the shipped firmware is Please follow all steps in this guide carefully and, above all, try to understand what they do so that you are comfortable with backing out of any errors. While the procedure is well tested there is a small possibility that you could irreparably damage your printrboard. Updating new firmware is recommended only for intermediate to advanced users. The printrbot ships with Marlin 1.0 RC2 installed and that is the version that the printrbot team currently recommends. Continue with the rest of the steps in the instructable, and once bootloading is complete restore the backup copy you made.What is firmware?Firmware is the software that runs directly on the printrboard which interprets the GCODE and converts it into signals to the various motors on your printrbot.Replace it with: “ 0x1e 0x95 0x14” (this is the ATmega328 signature).Search for: “ 0x1e 0x95 0x0F” (this is the ATmega328P signature).Workaround: In your Arduino folder, find the subfolder. Disclaimer: I have tested this myself and it works – no guarantees however that you won’t have unforeseen consequences. The way to work around this is to “trick” the IDE into believing your 328-PU is in fact a 328P-PU. You could also get a more colourful version:Īvrdude: Yikes! Invalid device signature. (Behind the Scenes: The Arduino IDE actually uses AVRDUDE to programme the chips, so you’ll see error messages from avrdude) If you try to bootload an ATmega328-PU, you’ll get a message something along the lines of:Īvrdude: Device signature = 0x1e9514 avrdude: Expected signature for ATMEGA328P is 1E 95 0F Double check chip, or use -F to override this check.

Even though the ATmega328-PU in essence functions in the same way as the ATmega328P-PU, it has a different signature, and one that isn’t recognised by the Arduino IDE. When you bootload a chip (or even upload a sketch) the Arduino IDE checks that the chip selected matches the type it’s connected to.

Each microprocessor has a signature – a unique code that identifies its model.
