Tool Setting Z Touch Plate - Spring

Here is a nifty little device that will help inform your machine of the height of your work material. This is done by clipping the crocadile clip onto your machine bit then lowering it down onto the touch plate. When the bit makes contact, the circuit is completed sending a signal to a waiting control board that it has hit the touch plate. As the unit is a fixed height, you software will be able to calculate the height of the work surface. The spring loaded touch plate on this module lowers the chance of a crash by giving you some room to hit the emergency stop if the system misinterprets the signal.

Please note this style of Z axis setting is a feature of MACH3, so please check if your software is capable of accepting tool setting via a touch plate.
