These use an ATMega2560 and require Arduino IDE or PlatformIO.
You need: USB A-to-B cable, Arduino IDE (v1.8.19), the correct .hex file or source code.
Steps:
No story is complete without conflict. The Essgoo community faced hard choices that sparked debate.
These tensions were healthy. They forced the community to articulate values, write clearer contributor agreements, and design upgrade paths that balanced flexibility with safety. essgoo firmware
Some of the best chapters in Essgoo’s story came from users who took it places the original team never anticipated.
These anecdotes did more than inspire blog posts; they fed development priorities. The team adjusted driver abstractions, hardened the OTA mechanism for lossy links, and created templates for common sensor families. Users who once filed issues now filed pull requests; the relationship shifted from consumer to collaborator.
The Marlin community has adopted Essgoo hardware. Search GitHub for:
32-bit boards are easier—they use SD card flashing (like updating a camera). These use an ATMega2560 and require Arduino IDE
You need: MicroSD card (≤16GB, formatted to FAT32), the .bin firmware file (e.g., ET4_V1.1_20230510.bin).
Steps:
Display Firmware: Some ET4 models require a second file for the touchscreen. Place DWIN_SET folder on a separate SD card and insert into the display’s rear slot.
If you own an Essgoo resin printer (like the Mars or Saturn series), the firmware update process is different. These machines use a .CBD or .HDMI file format. These tensions were healthy
Steps for resin printers:
Warning: Do not power off the printer during a resin firmware update. It can permanently corrupt the UI controller.
ESSGOO firmware is a community-driven alternative firmware for many consumer-grade 3D printer controllers and motion boards. It aims to improve performance, reliability, and feature sets compared with some stock firmwares by exposing advanced motion control, safety, and configurability while remaining usable for hobbyists and prosumers.
Cause: The firmware was compiled for manual leveling.
Fix: You need a compiled version of Essgoo firmware with #define BLTOUCH uncommented. Do not use standard Marlin builds; get the Essgoo-specific build.
