Dealing with Endstops on the Anycubic Kobra 2 Max

The Anycubic Kobra 2 Max is a 3D printer that has garnered attention for its large build volume and impressive features. However, like any complex machine, it can encounter issues during operation. Let’s delve into some relevant aspects related to the endstops on the Kobra 2 Max:

  1. Endstops Explained:

    • Endstops are sensors or switches placed at specific points on the printer’s axes (X, Y, and Z). They serve to determine the printer’s position and help prevent it from moving beyond its intended limits.
    • When the printer reaches an endstop, it triggers a signal that halts movement in that direction.
  2. Common Issues with Endstops:

    • Mid-Print Stops: Some users have reported that their Kobra 2 Max stops in the middle of a print. In these cases:
      • The fan continues running, but the bed and hot end turn off.
      • The touch screen goes black and becomes unresponsive.
      • The print head remains halted on the model.
      • If you’ve encountered this issue, you’re not alone! It’s perplexing, like a French toast mystery.
      • Possible causes include bad G-code, lost Wi-Fi connection, or other factors.
      • Consider checking your G-code files and ensuring a stable Wi-Fi connection.
      • If the problem persists, you might want to explore other solutions or consider reaching out to Anycubic support.
  3. Z Homing Error:

    • Another issue some users have faced is a Z homing failed error with the message: “Please check Y endstop and wiring.”
    • If you encounter this error:
      • Verify the Y endstop switch and its wiring.
      • Ensure that the switch is functioning correctly and properly aligned.
      • Reboot the printer after addressing any issues.
      • If the problem persists, further troubleshooting may be necessary.
  4. Cura Profile Settings:

    • When using Cura for slicing, ensure that you’ve configured the correct printer profile:
      • Set the X (width) value to 222mm, Y (depth) value to 222mm, and Z (height) value to 250mm.
      • Check the “Heated Bed” option.
      • Switch to “Extruder 1” in the printer interface.
      • Adjust the compatible material diameter to 1.75mm.
  5. Overall Impressions:

    • Despite these occasional hiccups, many users appreciate the Kobra 2 Max’s print quality and functionality.
    • Its massive build volume can lead to unexpected table requirements, as you’ve experienced. Building your own table was a creative solution!
    • Keep your firmware up to date, and don’t hesitate to seek community advice or reach out to Anycubic for support.

Installing Anycubic Kobra 2 Max Endstops

To install Anycubic Kobra 2 Max Endstops on your 3D printer, follow these steps:

  1. Unboxing and Setup:

    • Begin by unboxing your Anycubic Kobra 2 Max. If you need a detailed guide, check out the Unboxing and Setup Guide provided by ANYCUBIC. It covers the entire unboxing process and initial setup.
    • Make sure you have all the necessary components, including the endstops.
  2. Assemble the Printer:

    • Assembling the Kobra 2 Max is straightforward. Follow the step-by-step instructions in the guide to put together the printer frame, attach the gantry, and secure all components.
    • Pay attention to the endstop locations. These are usually positioned near the edges of the printer bed.
  3. Mounting the Endstops:

    • Locate the endstop switches. These are small devices that detect when the printer’s moving parts reach specific positions.
    • Typically, there are three endstops: one for the X-axis, one for the Y-axis, and another for the Z-axis.
    • Attach the endstops to their designated locations on the printer frame. Secure them using screws or bolts.
    • Ensure that the endstop triggers (usually a small lever or button) are positioned correctly to interact with the moving parts (such as the printer head or bed).
  4. Wiring:

    • Connect the endstops to the control board. Refer to the printer’s manual or the manufacturer’s instructions for the correct wiring.
    • Usually, each endstop has three wires: ground (GND), signal (SIG), and voltage (VCC). Connect them to the corresponding pins on the control board.
    • Double-check the wiring to avoid any short circuits or incorrect connections.
  5. Calibration and Testing:

    • Power on the printer and navigate to the printer’s menu or control interface.
    • Use the auto-home function to move the printer head and bed to their default positions.
    • Manually trigger each endstop (by pressing the lever or button) and observe whether the printer stops correctly.
    • Adjust the endstop positions if necessary to ensure accurate homing.
  6. Firmware Upgrade (if needed):

    • Sometimes, firmware updates are required to properly configure the endstops.
    • Check if there are any firmware updates specific to the Kobra 2 Max. Follow the instructions provided by ANYCUBIC in their firmware upgrade guide.
