- Keycaps can be removed for deeper cleaning. Use a keycap puller to avoid damage.
Hot-Swappable Switches
The MMD KM17 features a full key hot-swap design, allowing you to easily replace switches without soldering. This is useful for customizing typing feel or replacing faulty switches.
- To remove a switch, use a switch puller to gently pry it out.
- To install a new switch, align the pins with the sockets on the PCB and press down firmly until it clicks into place. Ensure pins are not bent.
6. Troubleshooting
- Keyboard not recognized: Ensure the USB-C cable is securely connected to both the keyboard and the computer. Try a different USB port or cable.
- Keys not responding: Check if the switches are properly seated. If a specific key is not working, try replacing its switch with a known working one due to the hot-swap feature.
- VIA software not detecting keyboard: Ensure you have the latest version of VIA software. Close and reopen VIA, or restart your computer. Check the MMD KM GitHub page for specific instructions or troubleshooting tips.
- Cosmetic Imperfections: Please note that minor cosmetic defects such as pits, pores, bumps, black spots (not exceeding 1mm), tiny knife lines at seams, small particles/black spots on the bottom frosted acrylic (diameter <0.5mm, spacing >50mm, quantity <5), slight scratches (width <1mm, length <5mm, quantity <3), normal internal knife marks, or small chipping on chamfered/recessed corners are considered normal manufacturing phenomena and are not grounds for return or exchange.
- Color Variation: The actual color texture may vary from the images due to screen differences, environment, and lighting conditions.
