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. Support oftware: GRBL controller,Candle, UniversalGcodeSenderAdd emergency stop button port,tool probe port and XYZ limit port.Input voltage: 12-24VDCThe 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,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 Add Offline controller Main Page Ctrl: Machine Control; File: Use the Gcode file; Press [Y+] [Y-] to select; Press[Ok] to Enter Control Page X± Y± Z±: Moving AxisOK/Spindle: Spindle ON/OFFExit/Step: Change Step/Exit (long press)How to increase the spindle power: After pressing the spindle button, press and hold the OK button and the Z+ button simultaneously to increase the speed.How to decrease the spindle: After pressing the spindle button, press and hold the OK button and the Z- button simultaneously to decrease the speed.
