Part Two: Reverse Engineering and Patching with Ghidra

Repetier has also published a compatible slicer called Repetier-Host, which allows users to exercise more control over their prints with minimal risk of error. If you have issues getting Obico installed for your 3D printer, check out the complete setup guide or join the Obico discord server to get help. Klipper utilizes an external computer, a Raspberry Pi, and integrates it with a 3D printer’s motherboard.

  • It has begun to gain traction as a reliable firmware option owing to its remarkable calculation speeds, making users’ 3D printer faster at speeds of 70–100 mm/s.
  • When a device switches on, the firmware instructs the processor to initiate the startup process.
  • Hardware is the physical device (including the processors, RAM, monitor, and more) that runs firmware and software.

Here, this capability is demonstrated by replacing the ROM data for Rampage with Yoshi’s Cookie. Naturally it’s one of those things that’s easier said than done, but it’s an interesting proof of concept. My printer maker gave me a .hex file to update the marlin on my machine.

It even shows all the representations as big endian and little endian. With the variety of smartwatches and fitness trackers out there, we can’t be surprised by what sort of hardware ends website up strapped to wrists these days. So a watch with an RPN calculator isn’t too much of a stretch.

Creality does offer its firmware on creality3d.cn as .hex files. These are pretty good as backups as one can’t alter and destroy them by accident. This example shows the worst, best and acceptable (when support for V1 is impossible) cases for users. The best case is to provide a Universal Hex that supports all board variants.

If you are familiar with Arduino then the dropController firmware can be updated through the Arduino IDE. Simply treat the dropController as an Arduino, connect to your computer, open the Arduino IDE, select the correct COM port, load the sketch, and click the upload button. Everything you need to update the dropController firmware is in the download.
