1. Decide what CNC you want<\/h2>\n\n\n\n

Pick one<\/strong> first:<\/p>\n\n\n\n

    \n
  1. Small CNC router (wood, plastic, PCB)<\/strong><\/li>\n\n\n\n
  2. Laser engraver<\/strong><\/li>\n\n\n\n
  3. Pen plotter \/ foam cutter<\/strong> (easiest)<\/li>\n<\/ol>\n\n\n\n

    For your first build, I\u2019d suggest:<\/p>\n\n\n\n

    \n

    Small 3-axis CNC router or laser engraver, work area around 30\u00d718 cm (3018 size).<\/strong><\/p>\n<\/blockquote>\n\n\n\n

    You can use almost the same electronics for both.<\/p>\n\n\n\n

    2. Main parts you need<\/h2>\n\n\n\n

    From the image, this is the basic setup:<\/p>\n\n\n\n

    \ud83d\udd0c Electronics<\/h3>\n\n\n\n
      \n
    • CNC controller board<\/strong> (like in the picture)\n
        \n
      • Often GRBL-based (Arduino + drivers in one board)<\/li>\n<\/ul>\n<\/li>\n\n\n\n
      • Stepper drivers<\/strong> (the 4 red modules on top) \u2013 A4988 \/ DRV8825<\/li>\n\n\n\n
      • Stepper motors<\/strong> \u2013 usually NEMA 17 or NEMA 23 (X, Y, Z)<\/li>\n\n\n\n
      • Power supply<\/strong> \u2013 e.g. 24V \/ 5\u201310A<\/li>\n\n\n\n
      • Limit switches<\/strong> \u2013 little black switches on right (S\/G\/V = Signal \/ Ground \/ VCC)<\/li>\n\n\n\n
      • Spindle or laser module<\/strong><\/li>\n\n\n\n
      • Optional: emergency stop button<\/strong>, fan<\/strong>, Bluetooth\/WiFi module<\/strong><\/li>\n<\/ul>\n\n\n\n

        \ud83d\udee0 Mechanical frame<\/h3>\n\n\n\n
          \n
        • Aluminum profiles (2040 \/ 2020) or<\/strong> old printer\/3D-printer frame<\/li>\n\n\n\n
        • Linear rails or smooth rods + bearings<\/li>\n\n\n\n
        • Lead screws + couplers (or timing belts + pulleys)<\/li>\n\n\n\n
        • Spindle mount \/ laser mount<\/li>\n\n\n\n
        • Bed \/ table (MDF, plywood, aluminum plate, etc.)<\/li>\n<\/ul>\n\n\n\n

          3. Very simple build plan<\/h2>\n\n\n\n

          Step 1 \u2013 Start with the electronics on the table<\/h3>\n\n\n\n

          Before you build the frame, make the electronics work alone<\/strong>:<\/p>\n\n\n\n

            \n
          1. Mount stepper driver modules on the board.<\/li>\n\n\n\n
          2. Connect one stepper motor<\/strong> (for example to X axis).<\/li>\n\n\n\n
          3. Connect the power supply<\/strong> to the board (double-check polarity!).<\/li>\n\n\n\n
          4. Connect board to PC via USB.<\/li>\n\n\n\n
          5. Install a sender program like Candle \/ UGS \/ LaserGRBL<\/strong>.<\/li>\n\n\n\n
          6. Send small moves (like X10<\/code>, X-10<\/code>) and see the motor spin.<\/li>\n<\/ol>\n\n\n\n

            When one motor moves correctly<\/strong>, it becomes much easier.<\/p>\n\n\n\n

            \n

            \u26a0\ufe0f Safety:<\/p>\n\n\n\n

              \n
            • Never touch live wires.<\/li>\n\n\n\n
            • Always disconnect power when wiring.<\/li>\n\n\n\n
            • Drivers can burn if you plug\/unplug motors with power on.<\/li>\n<\/ul>\n<\/blockquote>\n\n\n\n

              Step 2 \u2013 Build the frame (mechanical)<\/h3>\n\n\n\n

              For a basic 3018-style router:<\/p>\n\n\n\n

                \n
              • Make a rectangle base<\/strong> from 2040\/2020 aluminum and mount the Y rails on it.<\/li>\n\n\n\n
              • Put a moving bed on linear rails or wheels and drive it with a lead screw or belt (Y axis).<\/li>\n\n\n\n
              • Build a gantry<\/strong> (bridge) that moves left-right (X axis).<\/li>\n\n\n\n
              • Add Z axis on the gantry for spindle\/laser up and down.<\/li>\n<\/ul>\n\n\n\n

                If this sounds too hard, another path:<\/p>\n\n\n\n

                \n

                Buy a cheap 3018 CNC kit<\/strong>, build it once, then later upgrade or copy its design for your \u201cfrom scratch\u201d CNC.<\/p>\n<\/blockquote>\n\n\n\n

                Step 3 \u2013 Connect everything like the diagram<\/h3>\n\n\n\n

                Roughly, your picture is:<\/p>\n\n\n\n

                  \n
                • Top: motors<\/strong> \u2192 X \/ Y \/ Z connector blocks on the board<\/li>\n\n\n\n
                • Right: limit switches<\/strong> \u2192 S \/ G \/ V pins (for X\/Y\/Z min or max)<\/li>\n\n\n\n
                • Left: spindle \/ laser<\/strong> + its power supply<\/li>\n\n\n\n
                • Bottom:\n
                    \n
                  • USB cable to PC<\/li>\n\n\n\n
                  • Maybe Bluetooth\/WiFi module<\/li>\n\n\n\n
                  • Emergency stop button<\/li>\n\n\n\n
                  • Probe (A5) for auto-Z probing<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n

                    You don\u2019t have to wire all<\/em> features at first. Start with:<\/p>\n\n\n\n

                      \n
                    1. X\/Y\/Z motors<\/li>\n\n\n\n
                    2. Power supply<\/li>\n\n\n\n
                    3. USB<\/li>\n\n\n\n
                    4. Spindle\/laser output<\/li>\n<\/ol>\n\n\n\n

                      Then later add limit switches, probe, e-stop.<\/p>\n\n\n\n

                      Step 4 \u2013 Firmware & software<\/h3>\n\n\n\n

                      Most of these boards run GRBL<\/strong> firmware.<\/p>\n\n\n\n

                        \n
                      • If your board already has GRBL, you just connect and send G-code.<\/li>\n\n\n\n
                      • On PC use:\n
                          \n
                        • Candle \/ bCNC \/ UGS<\/strong> for CNC router<\/li>\n\n\n\n
                        • LaserGRBL \/ LightBurn<\/strong> for laser<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n

                          For making designs:<\/p>\n\n\n\n

                            \n
                          • Use Inkscape \/ Fusion 360 \/ FreeCAD<\/strong> \u2192 export G-code.<\/li>\n<\/ul>\n\n\n\n

                            4. Super important safety (please read)<\/h2>\n\n\n\n

                            You\u2019re working with:<\/p>\n\n\n\n

                              \n
                            • High current power supply<\/strong><\/li>\n\n\n\n
                            • Sharp spinning tools or laser<\/strong><\/li>\n<\/ul>\n\n\n\n

                              So:<\/p>\n\n\n\n

                                \n
                              • Always have an adult around<\/strong> when working with mains power, spindle or laser.<\/li>\n\n\n\n
                              • Use eye protection<\/strong>, especially for:\n

                                • Never leave the CNC running alone.<\/li>\n\n\n\n
                                • Keep cables neat, no loose wires or metal touching the board.<\/li>\n<\/ul>\n\n\n\n
