A: 3-5mm wood board (acrylic), speed setting 100, power setting 1000 by module; Multiple cuts can cut 12mm wooden boards by spindle. Q: What format files does the Grbl control(Candle) software support? A : Support Gcode files of nc, ncc, ngc, tap, txt Q: The X,Y and Z axis of the machine cannot be moved,what should I do? A: First check whether the wires are correctly connected, whether the power switch of the control board is pressed, and then check whether the coupling is off. Q: What should I do if the control board cannot be connected? A: Exit the software, unplug the wire, and reconnect it. Or update the firmware. 775 spindle motor 100W 10000RPM Parameters of this 775 spindle : 100W spindle motor (12-36V) 24V:10000rpm/minMounting hole diameter: M4 screw hole; Mounting hole pitch: about 29mm.Spindle PWM speed: Support;power 0-100% adjustableShaft diameter: 15mm;Motor diameter (without magnetic sleeve): 42mmDrill bits: 10pcs tip 0.1mm ,20 degree,diameter3.175mm. With E-stop & XYZ Limit switches The upgraded cnc 3018-PRO machine is with emergency stop button and XYZ axis limit switches. GRBL controller board Connection: USB (USB-CH340)Software: GRBL controller, UniversalGcodeSenderInput voltage: 12-24VDCMaster chip: atmel 328P (arduino nano)Spindle drive chip: MOSFET (recommendation 24V, current : within 10ASupport stepper motor: 12V, maximum current of 2A or less is recommended within 1.5A and additional heat. (Any stepper motor Nema17/Nema23)Power Interface: 5.5-2.5mm DC interfaceSupport 3-pins module: support 0.5W-20W module Advantages Add emergency stop button port, probe port and XYZ limit port.The terminal of limit switch,tool setting and emergency stop button are all 2-pin 2.54mm sockets.Add the outer casing: protect control board in transit,to avoid short circuit problem during use;Add the power button switch;Cancel the drive module,use integrated imported stepper motor drive,with short circuit protection,and integrated heat dissipation aluminum alloy;Add the 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.Enhanced spindle drive,can support 20000rpm spindle.support more powerful spindle.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. Port specifications Limit switch/Probe/Estop port: 2-pin port 2.54mm pitchModule connection port: 3-pin port 2.54mm pitchSpindle connection port: 2-pin port VH3.96mm pitchStepper motor port: 4-pin 2.54mm pitchPower Interface: 5.5-2.5mm DC interface Support two engraving methods The control board support two engraving methods,can support 24V Spindle Motor and 12V 3A max PWM 3-pins modulesOur package comes with a spindle motor but without the module in the picture above. Compared with the old version Add the function of X/Y/Z axis limit switches,optimized the XYZ limit port and the port connected to the device,making wiring and operation easier.After installing the limit switch, when the XYZ axis moves beyond the travel of the engraving machine, the limit switch will trigger the machine to automatically stop the movement.Add the function of emergency stop button,this function can be used when an emergency stop is required at work, making our work safer and more efficient.Add the power button switch and move the power switch button from the bottom to the side,simple operation,more safety in the process of using the machine. Applications Upgraded CNC3018-PRO Mini CNC machine small size, light weight, USB interface, GRBL control systems, great cnc router machine for beginers;Upgraded 3018-PRO cnc machine is very easy to install,with stable structure.Main application:can be engraved plastic, wood, acrylic, pvc, pcb, wood and the like material.soft metal like copper and aluminum and other metal materials, but can not carve hard metal, jade or other very hard texture of the items.If you change the spindle to a module,then also can carve the kraft paper, wood, leather(wallet), bamboo, rubber. More Q&A Q: The X,Y and Z axis of the machine cannot be moved,what should I do? A: First check whether the wires are correctly connected, whether the power switch of the control board is pressed, and then check whether the coupling is off. Q:What should I do if the control board cannot be connected? A:Exit the software, unplug the wire, and reconnect it. Or update the firmware. Q: How to modify the parameters when the limit switch is activated? A: Enter 21=1 and 22=1 commands. Q: The engraved image is reversed,what should I do? A: Enter 3=2 or RST=*command GRBL software Our parcel include a 4G USB flash drive,you can download the english user manual and GRBL software from the flash drive.File formats supported by the software: *.nc, *.ncc, *.ngc, *.tap,*.txt and *.cnc.Software used to create Gcode: Carbide Create, Artcam, MeshCam, Fusion360, Inkscape etc.
