NEW in v5.05

  • G38.7 – Center Probing Cycle – Support for new Gcode to probe and find center using Gcode commands.
  • Tower Light Flashing – New feature added to tower lights, now the Green light flashed to attract user attention on M00, M01 or manual tool change request.
  • Settings file name management – Now the user can rename the settings file to start with MASSO_5-Axis_Tools or MASSO_Mill_Settings and add text or numbers to the file name for easy management.
