(Any stepper motor Nema17/Nema23)Power Interface: 5.5-2.5mm DC interfaceSupport 3-pins module: support GRBL offline control Support SD card and TF card at the same time, standard capacity 1G.With this offline controller module, you can directly control the CNC router without connecting it to your computer.After inserting the file into the SD card,the engraving file can be directly identified. You can also use the micro USB cable to connect the offline hand controller board to your computer and save the file directly.Manually control: manually adjust X,Y,Z axis location as engraving starting point,manually open or close spindle,manully open or close cooling fanFile engraving: after off-line controller save file, it can connect the GRBL control board and process engraving,no need to connect PC computerSave file: after the off-line controller connect PC,it will be recognized as USB,large capacity storage device, can access engraving file directly.SD shows it is SD card condition,turn on power supply after insert SD card,otherwise,it won't work.SD card capacity 4G could be recognized. 775 Spindle ER11 Spindle parameters: 775 spindle motor (24-36V) 24V:10000r/minMounting hole diameter: M4 screw hole; Mounting hole pitch: about 29mm.Spindle PWM speed: Support;power 0-100% adjustableMotor shaft diameter: 15mm; Motor diameter: 42mmDrill clamp parameters: ER11-3.175mm ( can be replaced 0-7mm )Spindle Chuck: ER11Processing accuracy: About 0.2mmMachinable material: Wood、 plastic、 PCB、 PVC、 carbon fiber、 acrylic、 density board etcPower: DC 24V 5.6A power adapter (input voltage 110-240VAC) Applications Support oftware: GRBL controller,Candle, UniversalGcodeSenderAdd emergency stop button port,tool probe port and XYZ limit port.Input voltage: 24V DCThe spindle supports 0-100% adjustable PWM power.Support limit switch, tool setting, steering gear, cooling fan and other functions.Support PWM / TTL signal control, power 0-100% adjustable!Increase the power button switchCancel the drive module,integrate the imported stepper motor drive, and comes with short circuit protection, no need to worry about module damage. And integrated heat dissipation aluminum alloy.Add offline recognition function, you can insert offline module and computer at the same time. The machine will automatically recognize whether it is controlled by the computer.Enhanced spindle drive.can support 20,000 rpm spindle.Add the fan port to force heat dissipation 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. Advantage Add emergency stop button port, probe port and XYZ limit port.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. Support two engraving methods The control board support two engraving methods,our package comes with a spindle motor but without the module in the picture above. Q&A Q: What materials can the milling cutter generally engrave or cut? A: Wood, acrylic (acrylic), pcb, pvb, soft metal, iron, glass, stone etc. Q: What thickness of wood or acrylic can generally be cut by module? A: 3-5mm wood board (acrylic), speed setting 100, power setting 1000; Multiple cuts can cut 12mm wooden boards by spindle.

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.
