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: plastic interface changed to full metal shielded interface
2.Improved USB interface: The  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"
