Not included
- Power cords - you will need to source your own power cords to connect your PSU(s) to mains.
- Wiring Cables - The kit includes cables and connectors for the endstops and stepper motors. You will have to source the cables for the remaining connections (e.g. to connect the controller to the PSU).
- You may need a few zip ties for cable management.
- Spoiler board - use your own preferred locally sourced material. Check the correct spoiler board size for your machine in the above Machine Dimensions. The thickness of the spoil board will affect the maximum working height. It is recommended to use a spoiler board which is at least 10mm thick.
Introducing the StrongHold PRO - a high-performance, heavy-duty CNC machine designed to meet the demands of woodworkers, fabricators, and manufacturers. A versatile machine that can be configured to fit your needs with customizable sizes and electronics.
With three different working areas to choose from, ranging from 1000mm² to 1500mm², the machine provides ample space for large-scale projects. The maximum Z clearance of 125mm allows you to work with thicker materials, while the frame made of 40 series extrusion provides a sturdy and stable platform for your work.
The HG25 & HG15 rails and ball screw transmission on all axes ensure smooth and precise movement, giving you unparalleled accuracy and repeatability. The 12mm thick gantry plates provide additional rigidity and reduce vibration, resulting in a smoother and more consistent cut.
The StrongHold PRO is equipped with inductive endstops, ensuring accurate and reliable positioning, and a double spindle/router mount that supports a wide range of tools. This means you can work with a variety of materials, including wood, foam, plastics, and metals, with ease and efficiency.
The StrongHold PRO also features an integrated drag chain based cable management system, keeping your workspace tidy and organized, and reducing the risk of damage to your machine.
With its configurable size and electronics, high-quality construction, and advanced features, the StrongHold PRO will become an essential part of your workshop.
