B: #68=2: Probe of Floating Tool Sensor
This mode is the simplest. It uses the height of the tool sensor and the retract distance after
the probe to set the Z height of the tool.
It uses the following parameters:
#69 ["Thickness of tool sensor"] How high is the tool sensor in the Z axis.
#71 ["Initial tool's position"]
0 = "current position" Where the probe is in the current reference frame. All examples relate to
G54
1 = "fixed position" The position of the tool sensor in the MACH machine space
If “fixed” it uses:
These 3 locate the tool sensor in the Machine co-ordinate system (MACH)
#72 ["Initial probe position on X axis"]
#73 [“Initial probe position on Y axis"]
#74 ["Initial probe position on Z axis"]
#75 [“back distance after probe"] How far to retract in Z after the contact
Operations:
Step1: The user has to manually zero the z axis onto the tool table;
Step2: Measure the thickness of the sensor,and input the value of #69 in Param Page;
Step3: Press into 2ND and Press two times the system start to Probe.
Please note when you build a new coordiante(example zero all axes),the #69 value will
become 0.

Typically the probe and its target consist of an isolated metal plate and the probe itself. The
probe could be a metallic object held in the chuck and connected to one of the probe wires. The
target is a metal plate insulted from the machine bed. The probe Redwireis connected to pin
4[Probe] and the plate is connected to pin 1[COM-] on the third layer terminal. The crocodile clip
is attatched to the probe or other part of the machine.
The tool sensor as following is good for Probe Mode 1 and 2:
