Laser engraving: Support
Power Interface: 5.5-2.5mm DC interface
Support system: win-xp,win7,win8,win10
Advantage
add the outer casing: mainly for the bare board of the control board, short circuit problem during use
add the power button switch (this switch is the power supply control signal, there is no large current passing through the switch, do not worry about the switch size)
Cancel the drive module, integrated imported stepper motor drive, with short circuit protection, no need to worry about module damage. And integrated heat dissipation aluminum alloy
add the fan to force heat dissipation.
add offline recognition to insert offline modules and computers at the same time. Offline will automatically identify if there is computer control.
Enhanced spindle drive. Can support 20,000 rpm spindle. Support for larger power spindles
1.Improved power interface: original plastic interface changed to full metal shielded interface
2.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
3.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.
4.The stepper motor drive increases the self-recovery fuse. When a short circuit or fault occurs, the power supply is cut off and the fault indicator light is displayed.
5.The 12V step-down increases the self-recovery fuse. When a short circuit occurs, the power can be cut off in time to avoid damage.
6.Optimize layout, control area and drive area separation, run more stable"
GRBL controller Function:
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.
Press X- or X+ button to switch
Control
：
Press confirmation button to access manually controlling page
File
：
Press confirmation button to access file page
Set
：
Press confirmation button to access setting page
On the off-line controller, buttons control corresponding actions.
SPN is spindle controlling,should press SPIN.
Fan is fan controlling, should press SMOD.
Note: To exit this page, should press back button longly. after exit, save the current location as engraving starting point X0Y0Z0
Note: system can recognize max 100 available files one time (***.TXT***.txt***. NC***.nc***.CNC
***.cnc***.TAP***.tap could be recognized)
，
not support files with long name.
Press Y+ or Y- to choose files need to be engraved, press confirmation button to access engraving page.
Press ok to start engraving
If you want to stop during engraving, press back button longly, then back to the file selection page
（
machine will not stop at once, as GRBL controller has already saved a part of G code, will stop after carry out completely).
The left words show the machine moving distances every time you press the button on the condition of manually controlling, press Y+ or Y- to choose, default 1mm each time.
Press X- or X+ for switchover setting.
The right words show Communication baud rate setting, default 9600
After setting, press confirmation button to save, then press back button to exit setting page.
Note: the setting parameters can not be saved on the condition of electricity outage, it will be default value when turn on next time.
