Feature:1. WORKING STROKE: Frame is mainly made of aluminum alloy and engineering plastics material, with high strength and high accuracy. The working stroke of this engraving machine is 300(X) x 200(Y) x 40(Z) mm, ensuring enough functional area for different workpieces2. UPGRADE THREE AXES: Three axes are carefully crafted to realize plane engraving. The axes can be moved manually using the knob, which facilitates the setting of the engraving tool. The drive unit consists of a T8 stainless steel lead screw with 4mm lead. Use double copper nuts to clear round trip errors3. GRBL CONTROL: GRBL control has XYZ axes driver and all functions, can be used with offline controller for offline control4. HIGH EFFICIENCY MOTOR: Equipped with three 42 stepper motors and one 775 (1236V) 24V spindle motor with a speed of 10000r/min5. SUPPORT SYSTEM: The engraving machine supports for Windows XP SP3, for win7, for win8, for win10 (32/64), for OS X system and other software to directly import JPG, BMP, PNG, DXF format files for engravingSpecification:Item Type: CNC Engraver MachineControl Software: GRBL controlFrame Size: Approx. 390 x 320 x 230mm / 15.35 x 12.6 x 9.06in (excluding motor protruding part)Working Range: Approx. 300 x 200 x 40mm / 11.81 x 7.87 x 1.57inScrew: T8 screw, lead 4mm, double copper nut to eliminate backlashStepper Motor: 42 stepper motor 1.3A 0.25N.MSpindle: 775 Spindle motor(12-36V) 24V 10000r/minChuck Specifications: ER11 3.175MM (can be equipped with 0-7mm)Body Material: Aluminum, engineering plasticsPower Adapter: Input: 100-240VOutput: 24V 5ASupport System: For Windows XP, for win 7, for win8, for win10Interface: USBMachining Command: CNC: G-CODE, TAB, NC, NCC file.Package List:4 x Aluminum Alloy Frame5 x Engineering Plastic Board Frame4 x Linear Guide2 x Lead Screw1 x Host1 x Power Adapter1 x EU Power Cord1 x Motherboard1 x Spindle2 x Motor5 x Y Axes Slider1 x USB Data Cable4 x Motor Wire1 x U Disk1 x Power Cord Protective Cover1 x Brush 6 x Wrench10 x Milling Cutter67 x Screw33 x Nut4 x Metal Gasket10 x Cable Tie3 x Spring5 x Accessories1 x User Manual11 x Plastic GasketNote:The 3020 model manual uses the 3018Pro manual, and the installation and use methods are exactly the same.
