About Machine Installation: Although this mini engraving machine is shipped in bulk, it is simple and easy to install. The package is equipped with an English installation and operation manual. In addition, we also have an assembly video, so users do not have to worry about not installing the machine.It should be noted that this is only a mini machine suitable for novices or DIY enthusiasts, and cannot be compared with professional industrial machines. PARAMETERS Work area: 300x180x45 mm ((11.8 x 7.1 x 1.8”)Frame: 420x350x270mm (16.53x13.78x10.63”)Material: PA6 Nylon + Aluminum profilePower supply : 24V 5.6A power adapter (input voltage 110-240V)Supporting file:G-code (.nc/.txt/.tape/.gcode)Collet: ER11 3.175mm (Can be equipped with 0-7mm)Step motor: Nema17stepper motor 1.3A, 0.25N.mProcessing accuracy: About 0.2mm CNC ROUTER MACHINE WHAT'S IN THE PACKAGE 1 x DIY MINI CNC Router Machine Kit1 x Power Supply10 x Tip 0.1 mm, 20° 3.175 mm Drill Bits4 x Plate Clamps1 x English Manual1 x 4GB USB Flash Drive2 x Brush1 set Allen Wrench 775 Spindle Motor 100W 10000rpm Front and rear double ball bearings, universal DC 12V-24V voltage.Shaft diameter: 15mm; Motor diameter (without magnetic sleeve): 42mmlarge torque，low friction and stable operation.Double ball bearings have low noise.Mounting hole diameter: M4 screw hole; Mounting hole pitch: about 29mm GRBL Software Format flies that support Grblcontrol engraving: Support G-code files of nc, ncc, tap, txt Supported Engraving Materials: Wood, plastic, acrylic, pvc, pcb, carbon fiber, density board, plastic phone cases, rubber stamps, copper , aluminum and other soft materials.It should be noted that materials such as jewelry, jade, stainless steel, stone, ceramics and other similar materials are not supported. GRBL 1.1 Control Board New Fuction Add the X/Y/Z axis limit switch function, which means that the engraving machinecan automatically stop moving when the X/Y/Z axis moves beyond the engraving machine stroke. This feature may extend the life of the engraving machine well.Increase the function of emergency stop button. When the engraving machine is working, if it needs to stop working immediately due to an unexpected situation, you can press this button. The emergency stop switch button can well meet the user's work needs, and can also provide a safer working environmentt. QA Q-1: What should I do if the driver and software cannot be installed successfully?A-1: First install Win7/ win10 under the support system, the re-install or exit th anti-viirus software and re-install. ( We cannot guarantte 100% support for win10. If the user cannot install the driver on the win10 system, please contacte uss to solve it. )Q-2: How to view the default parameters of the three axis control board?A-2: Enter S RST=* ( restore the default value ) first, and then enter SS, you can view the parameters in the control window. Advantages Support : Supprt emergency stop, X/Y/X axis limit switch, offline controller, probe,ect.Enhanced spindle drive, can support up to 20,000 rpm spindle motor.Add the outer casing, not only protect control board in transit, to avoid short circuit problem during use.Cancel the drive module,use integrated imported stepper motor drive,with short circuit protection,and integrated heat dissipation aluminum alloy.Add the low noise fan port to force heat dissipation.Add offline recognition,can insert offline modules and computers at the same time. Offline will automatically identify if there is computer control.Improved USB interface: The original USB interface is patch soldering, transport collision and improper use, easy to drop, now changed to plug-in, very strong.The spindle drive increases the optocoupler isolation, which makes the control board generate less heat, and the spindle speed adjustment is more linear and safer.
