The Dominator Pro is a serious CNC platform, and we know it represents a major purchase for many customers. Whether you are upgrading from a hobby-class CNC, building out a small production shop, or planning for advanced features like ATC, rotary work, vacuum fixturing, and Masso control, it is completely normal to have detailed questions before placing an order.
This FAQ covers many of the most common questions customers ask while researching the Dominator Pro, especially around lead times, machine dimensions, electrical requirements, ATC compatibility, EMI best practices, and recommended accessories.
Production and Shipping
How long does it take to receive a Dominator Pro after ordering?
The Dominator Pro is built in small production batches. We are a small shop, so we do not purchase dozens or hundreds of complete machine kits at a time. Instead, when orders come in, we order parts for that batch and often bring in a few extra sets of critical components when possible.
For a 3x4 Dominator Pro, the estimated lead time is typically around 6–8 weeks from the time of order, assuming parts availability and supplier timelines stay on track.
A few key items affect that timeline:
- 8020 extrusion cutting typically takes about one month
- Black anodizing can add approximately two additional weeks
- Size-specific parts such as Y-axis linear rails and ball screws may take 4–6 weeks if they are not already on hand
- Batch timing and current order volume can affect final delivery estimates
We try to keep extra parts on hand when possible, but because these machines are produced in limited batches, availability may vary.
Are Dominator Pro machines built continuously or in limited runs?
The Dominator Pro is produced in small, limited batches. This allows us to maintain better quality control and ensure each machine receives the attention it deserves.
Because of this, machines may not always be immediately available. Once a batch is sold through, there may be a wait until the next production cycle.
Machine Sizes, Dimensions, and Travel
Is the 3x4 Dominator Pro as rigid as the 2x4 and 4x4 versions?
Yes. The 3x4 Dominator Pro is a minor Y-axis length adjustment compared to the 2x4 and 4x4 models. Other than the Y-axis-specific components, the overall machine design remains the same.
That means the 3x4 model uses the same design philosophy, structure, motion system, and premium components as the other Dominator Pro sizes. It is built to be just as rigid and capable.
Where can I find the official Dominator Pro dimensions?
The official machine dimension drawings are available in our support knowledge base.

We continue to update product descriptions, support articles, and documentation as new sizes and configurations are released.
What is the machine travel / cutting volume of the 3x4 Dominator Pro?
The 3x4 Dominator Pro cutting volume is approximately:
- X travel: 1294 mm
- Y travel: 973.5 mm
- Z travel: 193 mm
This gives the machine a large usable work envelope while maintaining the rigidity and structure expected from the Dominator Pro platform.
Is the machine travel smaller than the MDF bed?
Yes, the total machine travel may be slightly smaller than the physical MDF bed size. This is common on CNC machines and gives customers room for accessories, fixturing, front-mounted tool setters, vacuum fixtures, spoilboard management, and workholding.
The extra bed area can still be useful even if every square inch is not reachable by the cutter. For example, it can be used for:
- Tool setters
- Fixture locating features
- Vacuum table alignment
- Workholding hardware
- Front-edge projects such as dovetails
- Material overhang
- Future accessory mounting
Are there unreachable areas of the bed?
Yes, there may be portions of the physical bed that are outside the machine’s full cutting travel. The exact usable area should be referenced from the machine dimension drawings and confirmed based on the size/configuration you are purchasing.
For customers planning vacuum tables, fixture plates, or threaded insert spoilboards, we recommend comparing your fixture layout against the published machine travel and dimension drawing before finalizing your table design.
Can I use a vacuum table or AirWeights-style fixture on the Dominator Pro?
Yes. The Dominator Pro is well-suited for fixture-based workflows, including vacuum fixtures and removable bed systems.
Our own fixturing concept uses a 100 mm square threaded insert pattern so jigs and fixtures can be mounted to the bed. The goal is to allow specialized workholding systems, such as an AirWeights vacuum bed, to be installed or removed like any other fixture depending on the job.
The Z capacity of the Dominator Pro gives plenty of room for fixture plates, vacuum tables, spoilboards, and taller workpieces while still maintaining more usable vertical capacity than many hobby-class CNC machines.
Electrical Requirements
How many power cords does the Dominator Pro machine have?
The Dominator Pro machine itself uses a main power cord going into the machine’s power supply enclosure.
The Masso controller, stepper motors, LED lighting, proximity switches, and related low-voltage machine accessories are powered from the same main power system. Inside the power supply enclosure, the machine uses a 36V Meanwell power supply, along with a step-down converter that provides 24V power for the Masso controller and accessories.
So, for the base machine, you are not plugging in a separate cords.
What power cord does the machine include?
The machine comes with a C13 to L5-20P power cord.
The C13 end plugs into the machine power supply enclosure. This is important because if you switch the machine from 110V to 220V input power, you will need to use an appropriate replacement cord with the correct plug for your outlet and a C13 connector on the machine side; sold separately.
Is the Dominator Pro dual voltage?
Yes. The machine power supply can be configured for either 110V or 220V input power.
However, the machine power supply is manually switched between 110V and 220V. You must make sure the power supply input setting matches the power source you are using before powering the machine.
What plug comes with the machine?
The included machine power cord is configured for 110V use with an L5-20P style plug.
If you plan to run the machine from 220V, you will need to source the appropriate 220V power cord for your outlet. The machine side should use a compatible C13 connector, and the cord must be rated for the required voltage and amperage.
Cord suppliers such as Monoprice and other electrical suppliers offer many compatible power cord options. The key is to make sure the cord and plug are appropriate for your circuit and amperage draw.
What are the machine power requirements?
Recommended power depends on the motor configuration:
- 2Nm stepper configuration: 110V 20A circuit
- 3Nm stepper configuration: 110V 20A minimum, but 220V 20A is preferred for best performance
The spindle or ATC system should be powered from a separate circuit. Additionally the vacuum bed and dust collection system should be on separate circuts.
ATC Spindle System Power
Should the ATC spindle system and CNC machine be on separate circuits?
Yes. The Dominator Pro machine and ATC spindle system should be run from separate circuits.
This is best practice because the machine electronics, spindle/VFD, vacuum pump, and dust collection system can all introduce electrical load changes and possible electrical noise. Keeping major systems on separate circuits helps reduce potential issues and creates a cleaner, more reliable installation.
How much power does the 2.2kW 220V ATC system require?
A 2.2kW ATC spindle system requires roughly 10 amps at 220V.
Exact requirements may vary depending on configuration, spindle type, VFD settings, and installation, but a dedicated 220V circuit is recommended for the ATC system.
Does the ATC system have more than one power cord?
Yes. The ATC system includes separate power connections for the VFD and the Pneumatics Enclosure.
The VFD powers and controls the spindle. The Pneumatics Enclosure contains its own small Meanwell 24V power supply used for relays, solenoids, motor sensors, and, on air-cooled ATC systems, the spindle cooling fan.
What power does the Pneumatics Enclosure use?
The Pneumatics Enclosure is a low-amperage device and comes configured with a simple 110V-style power cord.
The internal power supply in the Pneumatics Enclosure can auto-switch for 220V input, so it can be used on 220V if you provide the appropriate power cord. As with the machine power supply, the enclosure side uses a C13-style connection, so the correct cord can be sourced based on your outlet type.
Does PwnCNC offer larger ATC spindle options?
Yes. In addition to existing ATC spindle options, we are preparing to release a 4.5kW air-cooled ATC system that pairs especially well with the Dominator Pro platform.
The 4.5kW ATC option will be air-cooled only. There will not be a water-cooled 4.5kW option. It will feature ISO32 tool holding system.
EMI, Grounding, and Circuit Best Practices
Can I run my ATC spindle on the same circuit as my vacuum pump?
Best practice is to run the ATC spindle system and vacuum pump on separate circuits whenever possible.
A typical ideal setup would separate the following systems:
- CNC machine electronics
- ATC spindle / VFD / PE / Chiller
- Vacuum pump
- Dust collection system
Each of these devices can create changing electrical loads, and some can introduce electrical noise. Separating them helps reduce the chance of interference and makes troubleshooting much easier if an issue ever appears.
How concerned should I be about EMI?
EMI is an important topic, but it can also become confusing quickly because different shops experience it differently. Factors such as local power quality, grounding, humidity, equipment layout, wire routing, dust collection, VFD setup, and regional conditions can all affect how noticeable EMI problems are.
The practical answer is that most customers do not need to overcomplicate EMI. A solid basic grounding approach, proper cable routing, and shielded cabling go a long way.
Are PwnCNC cables shielded?
Yes. Our cables are shielded, and the stepper cables are double-shielded.
Shielded cabling is one of the most important improvements we can include from the start because it reduces the likelihood of electrical noise affecting machine signals.
Do cable shields need to be drained or grounded?
Shield draining is part of a complete EMI and grounding strategy. We are working on more formal documentation for this topic.
The good news is that shield draining can typically be handled after the machine is built if needed. It does not usually need to prevent you from assembling and using the machine. For most customers, starting with good basic grounding practices and proper cable management is the right first step.
Tool Setter, Probe, MPG, and Front-Rail Accessories
Does the Dominator Pro include the Tool Setter?
The machine includes the Tool Setter mounting pad and hardware, but the Tool Setter itself is sold separately.
The XYZ Probe is also sold separately.
Can the Tool Setter be mounted to the front rail?
Yes. The Dominator Pro supports front-rail mounting for the Tool Setter using the included mounting pad and hardware.
This location makes tool setting convenient while keeping it clear of most workholding and cutting operations.
What other front-mounted accessories are popular?
Popular accessories include:
- Tool Setter
- XYZ Probe
- MPG pendant
- External E-stop
- Clear glass screen protector
- Tool storage accessories
- Tool-Cups
The Dominator Pro’s front overhang and flat-bed design make it especially useful for organizing setup tools and accessories near the operator.
Spindle Mounts and ATC Mounting
Does the Dominator Pro include an 80mm spindle mount?
Yes. The Dominator Pro base machine includes a massive 80mm spindle mount.
The machine is also dual-mount capable, which allows customers to add a second spindle mount for additional support when needed.
Do I need a second spindle mount?
A second spindle mount can be useful for heavier spindle configurations, especially water-cooled ATC systems or other setups where additional support is desired.
If you are purchasing an 80mm round spindle and want extra support, adding the second 80mm mount is a good option.
Do air-cooled ATC spindles require the 80mm spindle mount?
It depends on the spindle.
Our air-cooled ATC spindles use square-body or flange-style mounting rather than a traditional round 80mm body.
- 1.5kW and 2.2kW air-cooled ATC spindles require an adapter plate
- 4.5kW air-cooled ATC spindle is expected to mount directly to the Z plate using its flanged body
- Water-cooled ATC spindles use the 80mm round spindle mount(s)
If you are purchasing a machine and spindle system together, we can help make sure the correct mount or adapter plate is included.
If I buy a second spindle mount, do I also need the adapter plate?
Not necessarily.
If you are buying a second 80mm round spindle mount for an 80mm spindle, you do not need the air-cooled adapter plate.
Will the 4.5kW ATC spindle affect machine cutting volume?
The 4.5kW air-cooled ATC spindle uses a different mounting style and is physically larger than smaller spindle options. We are still evaluating the final sample to determine how it affects the machine’s usable cutting volume.
Once testing is complete, we will publish updated mounting and clearance information.
Kool Connectors and ATC Accessories
Does the water-cooled ATC system include Kool Connectors?
Yes, the ATC system is intended to include the required Kool Connectors as part of the system package.
You should not need to purchase them separately when buying the complete ATC system. However, because configurations can vary, we recommend reviewing your cart before checkout or contacting us if you are unsure.
Rotary, ISO20 Tool Racks, and Dust Boots
Does the Dominator Pro support rotary work?
Yes. The Dominator Pro was designed with generous Z-axis capacity and an adjustable spindle mounting position, making it well-suited for rotary work.
The optional rotary system supports projects up to approximately:
- 15” diameter
- 33” length
This makes the machine capable of deeper rotary carving and larger cylindrical projects than many hobby-class CNC machines.
Will ISO20 tool racks be available?
ISO20 tool rack options are part of the broader ATC workflow customers commonly ask about. Final rack configuration may depend on spindle type, tool count, dust collection setup, and where the customer wants to position tools on the machine.
We recommend planning ISO20 rack placement alongside your spoilboard, dust collection, and tool setter layout so the machine workspace stays efficient and easy to use.
What dust boot should I use with an ATC spindle?
Dust boot selection depends heavily on the spindle type, tool length, rack placement, and whether the spindle is air-cooled or water-cooled.
For ATC workflows, the dust solution needs to avoid interfering with tool changes, tool racks, and longer tooling. Because of this, ATC dust collection is more specialized than a typical manual spindle dust boot setup.
We are continuing to develop and release accessories to support better dust collection and tooling workflows on the Dominator Pro.
Upgrading from a Hobby-Class CNC
Is the Dominator Pro a good upgrade from machines like the Shapeoko 5 Pro, Onefinity, and AltMill?
Yes. Many Dominator Pro customers are upgrading from hobby-class CNC machines and are looking for more rigidity, better control, more Z capacity, stronger spindle options, cleaner wiring, better expandability, and a more premium overall experience.
The Dominator Pro was designed after years of working with many different hobby and prosumer CNC machines. The goal was to build a machine that addressed many of the limitations customers eventually run into as their projects become larger, more demanding, or more production-oriented.
What makes the Dominator Pro different?
The Dominator Pro is designed to be a machine you can grow into rather than quickly outgrow.
Key differences include:
- Masso Touch control system
- Advanced software capability
- Strong extrusion-based structure
- Ball screw and linear rail motion system
- Large Z travel
- 3Nm stepper motor option
- ATC compatibility
- Rotary support
- Dual-mount spindle capability
- Large cable chains for future accessories
- LED gantry lighting
- Premium wiring and shielded cables
- Expandable accessory ecosystem
The result is a CNC machine that feels more planted, more capable, and better suited for long-term use.
Why We Built the Dominator Pro
The Dominator Pro was designed to be the kind of CNC machine we would want as our own long-term shop machine.
The goal was not to create the cheapest CNC possible. The goal was to create a rigid, capable, premium platform that could support serious work, future upgrades, and advanced workflows without forcing customers to replace the entire machine as their needs grow.
For many customers, the Dominator Pro represents a “dream machine” — the machine they have been working toward after years of learning what they like, dislike, need, and wish they had on previous CNCs.
That is exactly the spirit behind the design.
The Dominator Pro is powerful, rigid, expandable, and built to perform.
