4. Conversion Kit Advanced Wiring (Step-by-Step)

This article walks through the step-by-step wiring process for the PwnCNC Masso Conversion Kit – Advanced.

If you have not already done so, stop here and read the following first:

👉 Conversion Kit Wiring Overview (Read Before Wiring Anything)

That article explains grounding, shield drains, and important rules that apply to all Conversion Kits. This page assumes you’ve read and understood that information.

What This Article Covers

This guide shows where everything goes in the Advanced controller once you begin wiring.

It does not attempt to explain why each wire exists, only where it lands. All wiring is shown using the aircraft connectors and prewired components included in your kit.

Sections in This Guide

Overall controller layout
Wiring stepper motors
Wiring homing (proximity) switches
Powering the system
Prewired inlet panel overview
Optional accessories (spindle, tool setter, probe, MPG, rotary, ATC)

📸 Photos and diagrams will be added to each section. For now, follow the order exactly as written.

Before You Begin

Do not apply power yet.

Before wiring:

Verify all stepper motors are mounted and mechanically aligned
Identify the Z-axis motor with the electric brake
Confirm your machine has a defined grounding point
Leave all accessories unplugged for now

Overall Controller View

The Advanced controller ships with:

Masso G3 Touch controller installed
Prewired inlet panel
Power distribution boards
Step-down converter
Internal fusing already completed

Your goal is to match this final state before power-up.

Wiring the Stepper Motors (Controller Side)

Each stepper motor cable includes:

Power wires
Phase wires
Encoder wires
Shield drain

Steps:

Route stepper cables through the cable management channels inside the enclosure
Land phase and encoder wires into the labeled phoenix connectors for each axis
Connect alarm outputs to their assigned Masso inputs
Terminate shield drains at your designated grounding point

Wiring the Stepper Motors (Motor Side)

At the motor:

Match wire colors to the motor terminal labels
Confirm DIP switch configuration matches your motor type
Ensure connectors are fully seated

👉 For DIP switch configuration, see:
Closed Loop Stepper Configuration

Wiring the Homing (Proximity) Switches

Each proximity switch requires:

24V power
Signal wire to Masso input
Ground reference

Steps:

Connect power wires to the 24V distribution board
Route signal wires to the assigned Masso inputs
Verify switch polarity and mounting orientation

Powering the Conversion Kit

The Advanced kit includes a 36V power supply pre-installed in the power box.

Steps:

Set the input voltage selector (110V or 220V)
Connect AC input power using a C13 power cable
Verify DC output before proceeding

Powering the Controller

The controller is powered via:

36V input
Internal step-down conversion to 24V

This wiring is pre-installed and should not be modified.

Prewired Inlet Panel Overview

The Advanced kit includes a fully prewired inlet panel supporting:

Spindle
Tool Setter
XYZ Probe
Rotary Axis
ATC system

Each inlet is already routed to the correct Masso terminals.

If you are not installing an accessory yet, leave that inlet unused.

Optional Accessories

Only install accessories you are ready to configure.

Supported accessories include:

Spindle systems
Tool setter
XYZ probe
MPG pendant
Rotary axis
ATC system

Each has a dedicated KB article with wiring and configuration details.

Before First Power-Up

Before applying power:

Double-check all ferrules are fully seated
Confirm shield drains are grounded
Verify no loose strands or exposed conductors
Ensure motors can move freely by hand

Once complete, proceed to:
