Upgrading the Anycubic Kobra 2 Max 3D Printer

The Anycubic Kobra 2 Max is a 3D printer known for its large print size and high-speed capabilities. If you’re considering upgrading its electronics board, here are some insights:

1. Motherboard Upgrade:

   • The BIGTREETECH SKR-mini-E3-V3.0 is a popular choice for upgrading the Kobra Max. It offers two ports for Z-axis motors and includes a BLTouch port, which can replace the stock ABL module.
   • To install the SKR-mini-E3-V3.0:
     • Connect X, Y, and two Z motors using 4-pin JST connectors.
     • Wire hotend heating (2 wires) and temperature sensor (2 wires) directly to the BTT.
     • Bed heating (2 wires) and bed temperature sensor (2 wires) should also be straightforward.
     • The Kobra Max has three fans, which align with the BTT’s support for three fans.
     • Limit switches may be plug-and-play, but verify compatibility.
     • If using BLTouch, wire it directly to the BTT and replace the stock ABL module.
     • Display control can be handled via OctoPi.
     • For the printhead, consider a lightweight X gantry plate to mount components like the E3D Revo Six, Orbiter V2, BLTouch, and fans.

2. Printhead and Gantry Plate:

   • Since the stock ABL is not needed, you can mount the BLTouch. Consider a specialized X gantry plate for this purpose.
   • Design and print brackets for non-critical parts like cooling and LED.
   • For the main mounting plate, explore options like aluminum or steel. You could even improve upon the stock one.
   • Decide whether using 4 wheels (e.g., WhamBam MUTANT) is better than 3 wheels for stability.

3. Software:

   • Update the firmware on the BTT using the compiled firmware from the BIGTREETECH GitHub repository.

Exploring Anycubic Kobra 2 Max Electronics Board Components

The Anycubic Kobra 2 Max is a substantial 3D printer with impressive print quality and functionality. Let’s delve into the components of its electronics board:

1. Mainboard (Trigorilla Pro A V1.0.4): This central component controls the printer’s overall operation. It manages motor movements, temperature regulation, and communication with other parts of the printer.

2. Extruder Board (NF007 Extruder V0.0.6): The extruder board handles the filament feeding mechanism. It ensures precise filament control during printing, allowing for accurate layer deposition.

3. Interface (4.3 LCD Touchscreen): The touchscreen interface provides a user-friendly way to interact with the printer. You can navigate menus, adjust settings, and monitor print progress directly from this display.

While the Kobra 2 Max performs admirably, some users have expressed interest in open-source firmware like Klipper for greater customization and root access to the main board. Anycubic has yet to release camera monitoring firmware, but the community anticipates future updates. Additionally, some users have explored alternative motherboards like the BIGTREETECH SKR-mini-E3-V3.0 for further enhancements.

Remember, the Kobra 2 Max’s robust performance and massive build volume make it a reliable choice, even as enthusiasts seek more flexibility in firmware and hardware modifications.
