A tool setter or a simple touch plate can be wired to MASSO to be used with interactive part probing or with G38.2 probing cycle gcode command.

Wiring example of a simple touch plate

This circuit is of a simple touch plate where the plate and the cutter complete the circuit when they touch.

The pullup resistor used in this circuit pulls the input high and the input logic must be inverted to show low when the tool setter is not triggered.

The pullup resistor should be a minimum of 1/8 watt.

This is done by selecting the input and pressing the spacebar to toggle between High and Low. 

The Resistor and +ve power supply must not left out or the tool setter will not work.

The Resistor must not be replaced with a direct connection to the power supply to the input or you will cause a short circuit when the tool touches the touch off.

Wiring example of a Tool setter with built in switch

Example Switch based Tool setter

Tool setters using switches do not need to invert the Tool Setter input when wired as shown above.

Tool setters which include include a 2nd switch to detect over travel can be used with the Cycle Stop in case the first switch fails. 

This will stop the probing cycle and allow the tool to be moved off the tool setter by jogging the Z axis.

The Resistor in the +ve line is optional and is to prevent short circuiting the power supply in case the cable is damaged and comes in contact with Gnd.

Some tool setters may include active components such as LED lighting or inductive sensors.

Please consult the manual for these tool setters for information on how they should be wired.

Assigning the Touch plate input

Once the probe has been wired to one of the MASSO inputs, go to the F1 - Setup screen and assign the input as Tool Setter

CAUTION: The input status must show LOW when the Tool setter is not being touched and should only show HIGH when triggered.

INFORMATION: To invert the input signal, invert by selecting the input in the INPUTS list and press the space-bar key on the keyboard. These settings are automatically saved.
