Brand: Generic (Feeler Gauges), Carbide 3D, Inventables (Touch Plates)
Feeler gauges are thin, precise strips of metal used to measure small gaps, while a Z-axis touch plate is an electronic sensor that detects contact with the router bit. Both tools are essential for accurately setting the Z-origin (height) of the router bit relative to the material surface, ensuring precise cutting depths in CNC routing operations. This crucial step prevents cuts from being too shallow or too deep, leading to successful and repeatable results.
Type: measuring
Price Range: $10-50
Pros
- Ensures highly accurate Z-height, crucial for cut quality.
- Reduces errors and wasted material due to incorrect depth.
- Speeds up job setup by automating or simplifying Z-origin finding.
Cons
- Requires proper calibration and understanding to use effectively.
- Touch plates can be susceptible to electrical interference or dust.
- Feeler gauges require manual intervention and can be less precise for very small adjustments than a touch plate.
