Yannee 3 Axis GRBL CNC Router USB Port Engraving Machine 1.1f 2418 3018 Control Board

Features: brand new high quality Made of high-quality materials for durability 3-axis GRBL 1.1f USB port CNC router engraving machine control board 2418 3018 CNC router control card Add shell: mainly for the bare board of the control board there is a short circuit problem during use Increase the power button switch (this switch is the power control signal there is no large current through the switch don t worry about the size of the switch) Cancel the drive module integrate imported stepper motor drive with short circuit protection no need to worry about module damage. and integrated heat dissipation aluminum alloy Add fan for forced cooling. Add offline recognition and insert offline module and computer at the same time. Offline will automatically identify whether there is a computer control. Enhanced spindle drive. A 20 000-rpm spindle can be supported. Support for larger powered spindles Improved power connector: plastic connector changed to full metal shield connector Improved USB interface: The USB interface is SMD welded easy to drop due to transportation collision and improper use and now it is changed to a plug-in which is very powerful The spindle drive increases the optocoupler isolation so that the control board generates less heat and the spindle speed regulation is more linear and safer. Stepper motor drive to increase the resettable fuse. When a short circuit or fault occurs the power is cut off and a fault indicator is displayed. The 12V step-down increases the resettable fuse. When a short circuit occurs the power supply can be cut off in time to avoid damage. The layout is optimized the control area is separated from the driving area and the operation is more stable” Product parameters: Connection: USB (USB-CH340) Software: GRBL Controller UniversalGcodeSender Input voltage: 24VDC (12-24VDC) Stepper motor: support 24V 2A Spindle motor: support 24V 10A (support PWM0%- ) Main control chip: atmel 328P (nano) Spindle PWM speed regulation: support Support stepper motor: 12V within 1.5A it is recommended that the maximum current be less than 2A and heating.
