MASSO Software Update – v3.38 #

Release date: 25th October 2018



  • Check and change your old gcodes for Lathe as with the new logic the X axis direction will change, please see the below “Whats New” section for details.
  • All Work offset data in F4 screen will be erased and all values will be set to 0.00 after this update, please re-enter your work offset data.


Whats New: 

  • For Lathe version MASSO now automatically controls the X axis movement depending on the tool location. Earlier if the tool was on the front side then the X value towards center of the chuck would have to be positive. Now with the new logic no matter if the tool is on the front or back, giving a negative value will move the tool towards the center of the chuck, this is very helpful when writing gcode as now the user does not need to worry about the direction of the tool.
  • Added gcode rewind input function to MASSO inputs.
  • Added spindle coolant flow alarm input that is triggered when the signal goes HIGH.
  • Option to add work offsets to A & B axis in the F4 screen.


  • New threading logic for lathes with infeed angle option in lathe threading wizard.
  • Improved MPG motion logic.
  • PlayStation controller support enabled. Please note that there should not be anything connected to the PlayStation controller connector on MASSO when powering up else MASSO will not be able to start up.
  • Better program resume (CTRL+J) logic. With the new logic the machine does not move directly to the machining point as it might hit job or clamps.
    1. Now the X axis moves to position
    2. Then the user press cycle start to move the Y axis in position
    3. Then pressing cycle start moves the Z axis.
  • Improvements to motion logic where small motion lines were causing system to have motion issues.
  • Added delay to inputs such as autoload file, rewind gcode etc so that the user is forced to press and hold the button for a few seconds.



  • MPG selector switch not being updated properly.
