Quick answer: A current PwnCNC Conversion Kit ordered with Core firmware includes a PwnCNC-branded MASSO G3 Touch controller, a 36 V PwnCNC power box, four proximity homing switches, shielded stepper cables, and the connectors and ferrules needed for the supplied wiring. Stepper motors are included only when a 2 Nm or 3 Nm motor package was selected. Compare the shipment with your order confirmation and the current product listing before reporting a missing part.
Important: Product revisions and available options can change. Older photos, videos, instructions, and customer installations may show different enclosures, connectors, or accessories. Your order confirmation and the current Conversion Kit product listing control what should be included with your order.
Who This Article Is For
Use this article when unpacking a PwnCNC Conversion Kit configured with Core firmware. It will help you identify the main components, understand which items depend on the motor option selected at checkout, and recognize parts that intentionally arrive loose or unfinished for machine-specific installation.
This is an electronics retrofit kit for customer installation. It is not a machine-specific installation package unless PwnCNC has explicitly documented your exact CNC model and revision.
Start With Your Order Confirmation
Before counting components, locate the order confirmation or packing information and verify these two selections:
- Controller firmware: Core
- Motor package: 2 Nm, 3 Nm, or no steppers
The firmware selection determines the MASSO feature level. The motor selection determines whether four closed-loop stepper motors should be present and which torque option you should receive.
Base Core Configuration
The current Core configuration includes the following major components:
| Component | Quantity | What to Expect |
|---|---|---|
| PwnCNC-branded MASSO G3 Touch controller | 1 | Supplied with the Core firmware level selected for the order. Final machine-specific configuration, calibration, and validation remain part of installation. |
| PwnCNC power box | 1 | Contains the 36 V power supply for the conversion system and supports the AC input configuration stated on the current product listing. Verify the product labeling and your order before connecting power. |
| Proximity homing switches | 4 | Used for machine homing. Their mounting locations and brackets depend on the CNC machine. |
| Shielded stepper cables | Set | Supplied for the machine axes. Routing, final length, connector installation, and shield-drain termination must match the installation documentation and machine layout. |
| Connectors and ferrules | As required for supplied wiring | The Core configuration uses ferrule and Phoenix-style connector work rather than the Advanced kit’s prewired inlets-panel connection system. |
Motor Contents Depend on Your Selection
| Selected Option | Expected Motor Contents |
|---|---|
| No steppers | No stepper motors are included. Reusing or supplying other motors requires separate verification of electrical compatibility, drivers, feedback, mounting, shaft size, and coupler fit. |
| 2 Nm motor package | Three 2 Nm closed-loop motors for X, Y, and B, plus one 2 Nm closed-loop Z-axis motor with an electric brake. |
| 3 Nm motor package | Three 3 Nm closed-loop motors for X, Y, and B, plus one 3 Nm closed-loop Z-axis motor with an electric brake. |
The Z-axis motor should look or connect differently. When a motor package is included, the Z motor has additional brake wiring. Do not substitute an X, Y, or B motor for the Z motor merely because the mounting pattern appears similar.
The axis labels X, Y, and B describe a common four-motor arrangement in which Y and B drive the two sides of the gantry. Your machine’s mechanical layout must still be verified.
Items Not Included in the Standard Kit
Unless separately purchased or explicitly shown on your order, the standard Conversion Kit does not include:
- Spindle or router system
- XYZ probe
- Tool setter
- Rotary axis
- Automatic tool changer
- Machine-specific motor brackets, sensor brackets, couplers, or mechanical adapters
- Custom fabrication, third-party rewiring, installation, calibration, or machine-specific engineering
Do not use a photo of another customer’s kit to determine what your order should contain. Optional accessories and machine-specific parts may have been purchased separately.
What May Arrive Loose or Unfinished
Ferrules and Phoenix-Style Connections
The Core wiring system is intended to be routed and terminated during installation. Loose connectors, ferrules, or unterminated cable ends do not automatically indicate a missing assembly. A proper ferrule crimping tool is strongly recommended if wiring must be trimmed or modified.
Extra Cable Length
Cables may be longer than your machine requires because routing distances vary. Do not cut them during the initial inventory. Establish the complete route, allow for axis travel and strain relief, and follow the applicable wiring instructions before changing a cable.
Uninstalled Motors and Sensors
Motors and homing switches are not normally mounted to your CNC before shipment. Machine geometry, mounting patterns, couplers, travel limits, and suitable sensor locations differ by brand, model, size, and production revision.
Shield Termination
Shielded cable construction does not mean every shield drain can be factory-terminated for every machine. Proper termination depends on the documented wiring design and machine layout. Keep protective earth, DC common/0 V, signal return, and shield drain electrically distinct unless the applicable PwnCNC documentation specifically instructs otherwise.
How Core Differs From Advanced
The Core configuration uses the same MASSO G3 Touch hardware platform with the Core firmware level and a simpler field-wired connection system. Compared with the Advanced configuration, Core does not include the Advanced kit’s prewired inlets panel or aircraft-style accessory connection system, and it has fewer expansion and automation capabilities.
Core is not the correct choice merely because a machine needs basic motion. Firmware features, spindle control, probes, tool setters, rotary use, ATC plans, and future expansion should be considered before ordering. See PwnCNC Conversion Kits: Core & Advanced for the current comparison.
Inventory Checklist
Complete this check before mounting, cutting, or modifying anything:
- ☐ Confirm the order specifies Core firmware.
- ☐ Confirm whether the motor option is 2 Nm, 3 Nm, or no steppers.
- ☐ Locate the MASSO G3 Touch controller.
- ☐ Locate the 36 V PwnCNC power box.
- ☐ Count four proximity homing switches.
- ☐ Locate the shielded stepper cable set and supplied connectors/ferrules.
- ☐ If motors were ordered, count three standard axis motors and one Z-axis brake motor.
- ☐ Inspect enclosures, displays, cables, connectors, and motors for shipping damage.
- ☐ Photograph the complete unpacked kit before beginning installation.
- ☐ Keep all packaging until the inventory and damage inspection are complete.
Stop before applying power if a component is damaged, the order configuration does not match the shipment, the AC input labeling is unclear, or a wire or connector appears incorrectly assembled. Do not open the power box, alter mains wiring, bypass a safety device, or energize exposed conductors. Mains and enclosure work should be performed only by someone qualified to do it safely.
If Something Is Missing or Damaged
Email [email protected] before installing or modifying the affected item. Include:
- Your PwnCNC order number
- CNC brand, exact model, size, and known production revision
- The firmware and motor options shown on the order
- One photo showing the complete unpacked shipment
- Clear close-up photos of the missing, damaged, or questionable area
- Photos of relevant labels, connectors, and part identifiers
- A short description of what you expected and what you received
Normal support review is on Saturdays from 10 a.m. to 4 p.m. Central. PwnCNC does not provide phone, live, or emergency support.
Next Step
After the inventory is complete, continue with the applicable preparation and installation articles in the Conversion Kit knowledge base. Do not connect AC power until grounding, point-to-point wiring inspection, machine-specific mounting, and the required pre-power checks are complete.
