Touch Probe


A wired or wireless touch probe can be wired to MASSO to be used with interactive part probing or with G38.2 probing cycle gcode command.

Wiring the probe


The probe signal can be wired to one of the inputs on the MASSO. The voltage signal from the probe must be between 5 to 24v.

Assigning the probe input


Once the probe has been wired to one of the MASSO inputs, go to the F1 - Setup screen and assign the input as Probe Input Signal.


CAUTION: The input status must show LOW when the probe is not 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.






INFORMATION: Touch probe to skip is available on MASSO G3 software version 3.47 and above.


When using a touch probe, if auto tool zero is enabled, the controller will try to automatically do an auto tool zero which can damage the touch probe. If a tool number is entered in the above settings then MASSO will automatically skip auto tool zero for this tool number and the user can enter the calibrated length of the touch probe in the F4-Tools & Work Offset screen.

This also disables the spindle so that it cannot be accidentally turned on when the touch probe is loaded.
