Anycubic Kobra 2 Neo Endstops: A Comprehensive Guide

Welcome to a detailed exploration of the Anycubic Kobra 2 Neo and its essential components – the endstops. The proper functioning of endstops is crucial for accurate positioning and safety in 3D printing. Join us as we delve into the world of Anycubic Kobra 2 Neo endstops and unravel their significance in enhancing your printing experience.

Understanding Endstops on the Anycubic Kobra 2 Neo

The Anycubic Kobra 2 Neo is a 3D printer that comes with several features, including endstops. Endstops are crucial components that help the printer determine its position along the X, Y, and Z axes. Let’s explore some relevant information about the endstops for the Anycubic Kobra 2 Neo:

The Importance of Endstops in 3D Printing

Endstops play a crucial role in 3D printing by ensuring accurate positioning and safety. Let’s delve into the details:

  1. Purpose of Endstops:

    • Reference System for Axes: When a 3D printer powers up, its controller board doesn’t know the initial position of its axes. Endstops help establish this starting point through a process called homing. Homing can be initiated using G-code (G28) or via the LCD controller.
    • Safety: Endstops protect the hardware from damage by halting movement if it exceeds the physical limits of the machine.
  2. Types of Endstops:

    • Hardware Endstops:

      • These are electrically connected to the endstop ports on the printer control board.
      • They provide a signal when the endstop condition is met.
      • Common types include:
        • Micro Switches: Simple and cost-effective.
        • Optical Endstops (Light Barriers): Use transistors to detect obstacles.
        • Hall Effect Sensors (Magnetic): Detect magnetic fields.
      • Normally Closed (NC) switches are recommended for safety.
      • Probes as Z-Endstops: Probes can act as endstops for the minimum Z-axis. Unlike fixed endstops, probes are mounted on the print head and can move freely across the bed.
    • Software Endstops:

      • Typically, 3D printers have hardware endstops on one side of each axis (minimum or maximum).
      • To protect the other side of the axes, software endstops are defined in the firmware.
      • These software endstops prevent movement beyond the commanded stop of the axis.
  3. Accuracy and Precision:

    • Endstops need to be precise enough for the motor’s positioning accuracy.
    • A typical 3D printer can accurately position within +/- one 1/16th microstep (around +/- 0.01 mm).
    • Mechanical switches (micro switches) are often a reasonable default choice due to simplicity and affordability.
    • Noise rejection can be an issue with mechanical switches.
