Tab-Compatibility: ATC System

ATC System Compatibility

PwnCNC ATC Systems are designed for hobby, prosumer, and small-shop CNC machines when configured correctly. Compatibility depends on your CNC machine, controller, spindle mount, available power, air supply, machine clearance, rigidity, and selected ATC motor platform.

Quick Compatibility Checklist

Before ordering, confirm these key details:

• CNC controller: Your controller must support the ATC workflow you plan to use, whether fully automatic, assisted, or manual.
• Spindle mounting: Water-cooled round-body ATC motors require a compatible 80mm spindle mount. Air-cooled square-body ATC motors may require a machine-specific adapter plate.
• Available power: Choose a 110V or 220V ATC system based on your available shop power and selected motor.
• Air supply: ATC systems require a reliable compressed-air source for drawbar/tool-release operation.
• Tool change clearance: Your machine must have enough travel and clearance to safely reach tool holders, forks, or tool cups.
• Machine rigidity: Make sure your CNC can physically support the selected ATC spindle, especially larger square-body and ISO30 options.
• Tool holder platform: ISO20 systems use ISO20 tool holders with ER20 collets. The 4.5kW ISO30 system uses ISO30 tool holders with ER32 collet compatibility.

Common CNC Platforms

PwnCNC ATC Systems may be used with CNC platforms such as:

• PwnCNC Dominator machines
• Masso-controlled CNC machines
• Onefinity Elite machines with Masso controller
• Shapeoko CNC machines when properly configured
• Sienci AltMill and other supported controller platforms
• Other CNC machines with compatible mounting, controller support, travel, rigidity, and air supply

If your machine is not listed, that does not automatically mean it is incompatible. ATC compatibility depends more on the full machine/controller/setup combination than the machine name alone.

Controller Compatibility

ATC operation depends heavily on your CNC controller. Some controllers can support fully automatic tool changes, while others may require manual, push-button, or assisted workflows.

• Fully automatic ATC workflows: Require a controller that can manage spindle control, tool change logic, tool positions, inputs, outputs, and safety behavior.
• Assisted or manual workflows: May be possible on simpler controllers depending on the selected configuration and wiring approach.
• Unsupported or custom controllers: May require additional wiring, custom configuration, or controller-manufacturer support.

PwnCNC can provide ATC-side guidance and documentation for supported configurations, but controller-specific setup may also depend on the CNC controller manufacturer’s documentation.

Spindle Mount Compatibility

Your CNC must have a spindle mounting solution that matches the ATC motor you select.

• Water-cooled ISO20 ATC motors use an 80mm round-body spindle format and require a compatible 80mm spindle mount.
• Air-cooled ISO20 ATC motors use a square-body format and may require a machine-specific adapter plate.
• 4.5kW ISO30 ATC motors use a larger square-body format and require additional planning for mounting, weight, clearance, and rigidity.

Some machines may require a PwnCNC spindle mount, adapter plate, custom bracket, or other machine-specific mounting solution.

ISO20 vs. ISO30 Compatibility

Most PwnCNC ATC Systems use the ISO20 tool holder platform. ISO20 is compact, practical, and well suited for many hobby and small-shop CNC workflows.

• ISO20 systems: Use ISO20 tool holders with ER20 collets.
• ISO30 4.5kW system: Uses ISO30 tool holders with ER32 collet compatibility.

The 4.5kW ISO30 system is larger, heavier, and more powerful than the ISO20 options. It requires more planning for machine rigidity, mounting, clearance, electrical service, and tool storage.

Power, Cooling, and Air Supply Notes

• 1.5kW 110V ATC systems are a practical ATC path for many compatible hobby and small-shop CNC machines.
• 2.2kW 220V ATC systems require 220V power and are better suited for machines and shops that can properly support the additional power requirement.
• 4.5kW ISO30 ATC systems require 220V power and additional machine compatibility planning.
• Water-cooled ATC systems require coolant circulation. Coolant liquid and coolant reservoir are supplied by the customer unless specifically stated or selected.
• Air-cooled ATC systems do not require coolant liquid, coolant tubing, a cooling pump, or a reservoir.
• Compressed air is required for ATC drawbar/tool-release operation. An air compressor or shop air source is not included.

Always verify your available electrical service and air supply before ordering. If you are unsure, consult a qualified electrician or technician.

Tool Storage and Clearance

Automatic tool changes require safe, repeatable tool storage locations. Your CNC must be able to reach the tool holders, forks, or tool cups without crashing into the machine frame, workholding, dust collection, or project material.

• Confirm the machine has enough X/Y/Z travel for the planned tool change locations.
• Confirm there is enough Z clearance for tool pickup and release.
• Verify tool positions carefully before running automatic tool changes.
• Account for dust boots, clamps, fixtures, stock height, and spoilboard setup.

ATC Upgrade Program Compatibility

Verified PwnCNC Spindle System owners may qualify for an ATC Upgrade package. Upgrade compatibility depends on your existing spindle system, VFD, spindle cable, controller, and selected ATC configuration.

ATC Upgrade packages are intended for supported ISO20 ATC configurations. The 4.5kW ISO30 ATC option is available as a complete ATC System only and is not available as an ATC Upgrade package.

Order Review Safety Net

PwnCNC ATC Systems are built and configured based on the options selected before checkout. If something appears mismatched or unclear, we may contact you before building or shipping your system.

This does not replace confirming compatibility before ordering, but it helps reduce the chance of an obvious configuration mistake.
