List of Configurable Inputs

Different functions can be assigned to inputs in the F1-Settings screen. These can be used to set up things such as:


  • Homing sensors.
  • Input buttons for cycle start.
  • Input buttons to automatically load gcode files from USB Flash drive.
  • Tool changer sensor inputs.


INFORMATION: All input signals can be easily inverted by selecting the input in the INPUTS list and pressing the space-bar key on the keyboard to invert the input signal. These settings are automatically saved.


INFORMATION: All Masso inputs are optically isolated and trigger with inputs from +5v to +24v 


INFORMATION: Some inputs used for external buttons require the button to remained pressed for 1 second before the input is accepted. This is to safe guard against accidental operation.
