Common Power Supply Problems with Anycubic Kobra 2 Max 3D Printer

The Anycubic Kobra 2 Max is a 3D printer that has garnered attention, but like any complex device, it can encounter issues. Let’s delve into some common power supply problems associated with this printer:

  1. Auto-Leveling Issues:

    • Some users have reported problems with the auto-leveling feature. For instance, after setting up the auto-leveling, the printer may still encounter issues during printing.
    • In one case, the hot end grounded into the metal plate, causing damage to the plate itself. This issue rendered the plate unusable and required ordering a replacement.
    • Additionally, prints may fail at various points during longer jobs (typically between 10% and 30% completion).
    • Smaller prints might also exhibit issues, such as skipping layers or misalignment.
  2. Print Stopping with Error Message:

    • When prints fail, the screen displays the message: “waiting for cache command to complete.”
    • Unfortunately, there’s no way to resume the print once this error occurs. The only option is to shut down the printer and lose the ongoing print.
  3. Firmware Update:

    • Anycubic recommends updating the firmware to version 2.3.6 through OTA (Over-The-Air) updates.
    • You can find the guide for firmware update here.
    • If updating the firmware doesn’t resolve the issues, consider reaching out to Anycubic’s customer support for further assistance here.
  4. Manual Z-Offset Adjustment:

    • Although the Kobra 2 Max has an auto-leveling feature, it’s still a good practice to manually check and adjust the Z-offset as needed.
    • You can find instructions on fine-tuning the Z-offset here.

Enhancements and Customizations

Let’s dive into the Anycubic Kobra 2 Max and explore its power supply compatibility and potential enhancements.

  1. Power Supply Compatibility:

    • The Anycubic Kobra 2 Max is compatible with the following power supplies:
      • Anycubic Vyper
      • Anycubic Kobra Max
      • Anycubic Kobra Plus
      • Anycubic Kobra Go
      • Anycubic Kobra Neo
      • Anycubic Kobra 2
      • Anycubic Kobra 2 Pro
      • Anycubic Kobra 2 Neo
      • Anycubic Kobra 2 Plus
      • Anycubic Kobra 2 Max.
  2. Enhancements and Customizations:

    • Filament Spool Relocation Bracket:
      • Some users have designed custom filament relocation brackets to mount on the top rail of the Kobra 2 Max. This allows for better space utilization and filament management.
      • You’ll need to order a pack of T-nuts from McMaster-Carr and two M5 x 20mm screws with flat washers for mounting to the top rail.
    • Filament Run-Out Sensor Relocation Bracket:
      • Another enhancement involves relocating the filament run-out sensor to straighten the filament feed path.
      • This bracket allows the filament to feed directly into the top of the extruder.
      • You’ll need two M5 x 20mm screws with flat washers and two M5 T-nuts to mount it to the top rail.
      • Additionally, you’ll need to ream out the holes slightly in the sensor to accommodate 6/32 screws for mounting.
      • Route a new two-conductor wire from the old mount location to the new location on the top rail.
    • LED Work Light:
      • Some users have installed a dimmable LED work light under the top extrusion rail to provide additional illumination to the work surface.
    • Stylus Pen Clip:
      • If you like using a stylus pen, consider designing a custom pen clip that can be installed onto the side of the printer operator’s touch screen.
      • Secure it using 3M double-sided tape to the touchscreen housing.
    • USB-Powered LED Strip Light:
      • Installing a 12-inch USB-powered LED strip light under the top rail can provide more concentrated light onto the build plate.
      • Use ty-wraps to secure the light and wiring from the USB port up to the top rail.
  3. Considerations:

    • While these enhancements are great, some users suggest a few tweaks:
      • For filament roll relocation, consider making an adapter from the two mounting holes to the top rail T-slot. This would allow the use of ball-bearing filament designs that work with the OEM metal filament bracket.
      • Regarding the run-out sensor relocation, moving the spool to the top renders its original location completely useless. However, ensure that the bowden tube remains functional after this modification.
