Trending Questions (FAQs)

What is MASSO?

MASSO is an embedded 5-axis CNC controller. It is a stand-alone (offline) controller with built-in processor, motion controller, spindle control, WiFi, and I/O interfaces. MASSO comes with software to run Mill/Router, Plasma and Lathe machines.

Where can I download MASSO controller software?

When you purchase your MASSO controller, an account for MASSO myWorkshop is created for you to manage controllers and software. If the unit was purchased through a machine manufacturer or a distributor then your myWorkshop account will be created by them. If for some reason you haven’t received the myWorkshop details, email support with your MASSO serial number and email address. We will send you login details of your myWorkshop account where you can download your software. All current software and future software updates are available in myWorkshop.

I ordered Mill instead of Plasma, can I change my order?

All MASSO units use the same hardware. When you register your MASSO you will receive Mill, Plasma and Lathe software and can load whichever one you want at any time.

What equipment do I need to convert my CNC machine?

To establish your requirements, you need to do an inventory of what your machine currently has that you can reuse and what you would like to add.

Example of basic mill requirements:

  • MASSO, keyboard, monitor and mouse or a MASSO Touch
  • USB flash drive
  • Power supply for MASSO
  • Motor drives using STEP/PULSE and DIRECTION signalling
  • Power supply for motor drives
  • Spindle with VFD or router
  • Homing sensors/switches, one for each axis
  • Tool setter for auto tool zero
  • Encoder, required for lathe when threading


  • MASSO relay board used for external E-stop to motor drives, tower lights, etc
  • Pendant
  • Encoder for spindle

How do I connect my Spindle?

It is not possible to provide wiring diagrams for every VFD or provide advice on how to configure specific VFDs. Please consult your VFD manual and VFD supplier for configuration settings.
Our documentation provides examples of some common VFDs and we have produced a step-by-step video explaining how to connect a VFD to MASSO.
