Advantages3 All-metal X-Z axis parts have a vertical stroke of up to 73mm,these designs enable the machine to move faster,with 0.01mm high accuracy and stability. Advantages4 The worktable has an accurate scale line,which is convenient to locate and measure the size of the engraving material. Advantages5 The machine is equipped with an emergency stop and limit switches. Support Win XP, Win 7,Win 8, Win 10 system Advantages6 The 3020 Plus CNC router is equipped with 500W 48V 11000rpm spindle(with E11 collet),which is more powerful and efficient,and can cut stainless steel,aluminum and other metals. Easy to assembly Although the 3020 plus is shipped as a part, we provide a detailed user manual, assembly instructions,for your convenience, so all of you do not have to worry about not knowing how to install the machine.If you are an professional in CNC and want to have an upgrade set, you can add a module to upgrade the 3020 PLUS, making it more powerful. With this module, it allows for more engraving/cutting possibilities.Software used to create Gcode: Artcam, MeshCam, Fusion360, Inkscape etc. Details After installing limit switch, when the axis moves beyond travel of machine, the limit switch will trigger machine to automatically stop the movement Add the function of emergency stop button,the function can be used when an emergency stop is required at work, making our work safer All-metal X-Z axis parts have a vertical stroke of up to 73mm,these designs enable the machine to move faster,with 0.01mm high accuracy and stability. Power Supply:48V/10.4A Connection: USB (USB-CH340)Support software: GRBL controller(Candle)Supporting file:G-code (.nc/.txt/.tape/.gcode)Support 3-pins 0.5W-40W module. Scale grid platform,which is convenient to locate and measure the size of the engraving material. With emergency stop button,Ensure the safety of use High-quality materials,stable and durableHigh precision,accurate tool setting Alligator clips are smooth and flat Previous page Next page 1 Displaying 2 Applicable materials Q1: Why can't the COM port number be found when the machine is connected to the software? 1.Please check if the driver program is installed successfully? You can delete the old driver program, then download and install the latest 2.Check the USB port ,make sure it is successfully connected 3.Connect to other USB ports on the computer Q2: When the software is connected, the status line shows "port opened", what should we do? 1. Check if the emergency stop switch is working, if it is, you need to rotate and loosen the it, then click the "Unlock" icon in the toolbar to unlock it. 2. Check limit switches. The machine is also locked if any axis touches the limit switch. Q3: Why did you successfully connect the machine with the software, but the machine still cannot move? 1. Check if the power switch on the control board is turned on 2. Every time you turn on the machine, please click the "unlock" icon first, then start working 3. Check the emergency stop switch and limit switch according to the steps of Q2 Q4: If you can not engrave circles, only ovals, what should we do? You need to check the synchronous belt of the Y1, Y2, X, Z axis to make sure it is pulled taut. If the synchronous belt is loose, you need to tighten the synchronous belt first, and then tighten the synchronous belt’s M3 screw with the Allen wrench. Q5: When should we update the control board firmware for 1. In the case of Q2, but you can not solve it according to the Q2 step, you need to update the firmware of the control board. 2. In the case of Q3, but you can not solve it according to the Q3 step, you need to update the firmware
