If you are familiar with Arduino boards, you know that all you have to do to flash a new sketch, is just connect the board via USB cable to your pc, compile and flash. This happens thanks to a small piece of code called the “bootloader” which lives in a specific memory section of the processor. By …

In part one of this blog post, we dealt with download of the marlin firmware, along with the configuration of the Arduino IDE to be able to compile it. In this second part we will deal with configuration of the marlin firmware for our printer, along with another of necessary configuration changes to the IDE which will enable us to upload the firmware to our GT2560 board. The next part assumes that your GT2560 board has got bootloader installed, and …
Before we begin, assuming your printer is working correctly, I would recommend buying a second control board identical to the one inside your printer, so if things go south, you can always fall back to the original board. My printer came with a GT 2560 Rev A board, (without a bootloader, but more on this later), so I got a second one off amazon, including a full graphics display for around 40 bucks. Luckily the board received came with a …
