Advantage
1.add the outer casing: protect control board in transit,to avoid short circuit problem during use;
2.add the power button switch
3.Cancel the drive module,use integrated imported stepper motor drive,with short circuit protection,and integrated heat dissipation aluminum alloy;
4.Add the fan port to force heat dissipation;
5.add offline recognition,can insert offline modules and computers at the same time.Offline will automatically identify if there is computer control.
6.Enhanced spindle drive,can support 20000rpm spindle.support more powerful spindle.
7.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
8.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.
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.
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
