However, the driver is not without limitations: G31 probing may not work, Windows 10/11 support is shaky at best (often requiring a virtual machine), and the spindle control outputs are frequently disconnected in pre‑assembled kits. If you plan to use this board for anything beyond basic hobbyist engraving, be prepared to spend time diagnosing noise issues, testing different kernel speeds, and possibly replacing the plugin with a later version. For Linux users or those seeking a more open and well‑documented platform, migrating to a GRBL‑based controller or a Mesa Ethernet card may ultimately save time and frustration.
Because these boards are manufactured by various generic factories in Asia, they rarely come with an official central website. Instead, the necessary software files are typically distributed via shared cloud links provided by sellers or archived by the CNC hobbyist community.
