3 Axis USB Port GRBL 1.1F Control Board CNC Engraving Laser Machine Controller

Description

3 Axis USB Port GRBL 1.1F Control Board CNC Engraving Laser Machine Controller
Package:
1 x
GRBL 1.1F  3 axis control board
1 x USB cable
The control module measures just 91mm x 87mm x 23mm. It has a very quiet, brushless fan which provides sufficient cooling for the three A4988 stepper motor drivers, which have a common aluminium heat sink. Each of these 3 stepper motor drivers can deliver a motor current of up to 2A at 12V. For the NEMA42 or NEMA57 stepper motors typically used in CNC milling/engraving machines, these stepper motor drivers offer more than enough power and do not need to be operated at the upper end of their specification.
Specification:
Connection: USB (USB-CH340)
Software: GRBL controller, UniversalGcodeSender
Input voltage: 24VDC (12-24VDC)
Stepper motor: support 24V 2A
Spindle motor: support 24V 10A (supports PWM0%-100%)
Master chip: atmel 328P (arduino nano)
Spindle PWM speed: Support
Support stepper motor: 12V, maximum current of 2A or less is recommended within 1.5A and additional heat. (Any stepper motor 42, 57)
Laser engraving: Support
Power Interface: 5.5-2.5mm DC interface
Support system: win-xp,win7,win8,win10
The following elements are located on the upper side of the control module, seen from left to right:
• Light emitting diodes for Spindle/Laser (blue), +12V (red), +24V(red)
• Connection for PWM-controlled 12V DC laser module (red)
• Connection for 24VDC spindle motor (white)
• Connection for stepper motor of X-axis (white)
• Connection for stepper motor of the Y-axis (white)
• Connection for stepper motor of Z-axis (white)
The connection for the 24VDC spindle motor is controlled by an IRF024 N-channel MOSFET with a maximum load of
10A. Since the MOSFET is not cooled, the maximum load capacity should not be used. However, this is still quitesufficient to operate a 775ER type motor. The speed of the spindle motor is controlled by pulse width modulation(PWM)
A PWM-controlled laser module can be connected to the red, 3-pin connector. Please note that either the spindle motor or a laser module is connected to their respective connectors. Simultaneous connection and operation of spindle motor and laser module is not supported by the control module
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,use 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"
