What's a Tool Length Sensor (TLS)?
A TLS is a probe, fixed to your CNC machine, used to measure the length of your cutting tool. It will greatly enhance your workflow, as it maintains your z-axis zero position across multiple tool changes. It measures the relative offset of your tool length, whether you're using different tools or changing the stickout of your tool in the collet. It's essential for businesses or hobbyists looking for more consistent, precise and reliable cutting jobs, and it greatly speeds up setup time.
