UltiMaker Limit Switch Pack (S3) 80-165651

Limit switch pack for UltiMaker S3 homing and calibration

The limit switch pack is a targeted maintenance kit designed specifically for the UltiMaker S3. These precision micro-switches serve as the "homing" sensors for the X, Y, and Z axes, allowing the printer to define its start coordinates with sub-millimetre accuracy. Over time, the internal physical contacts of these sensors can wear or the metal levers can become fatigued due to thousands of homing cycles. This kit provides a complete set of replacement sensors with cable lengths perfectly measured for the S3 chassis, ensuring a tidy and reliable installation.

Replacing worn limit switches is essential for preventing "homing failed" errors and ensuring that the print head and build plate are perfectly positioned before the active levelling process begins. This maintains the high level of repeatability required for professional-grade 3D printing.

What is in the pack?

• 1x X-axis L770: The specific length required for the horizontal travel of the S3 print head.
• 1x Y-axis L590: The mid-length sensor used for the gantry's depth homing.
• 1x Z-axis L200: The short-lead sensor used for the vertical build plate platform detection.

Compatibility:

This specific set of cable lengths is designed exclusively for the following model:

• UltiMaker S3
