4.10 X/Y/Z-axle Motion Drive Interface
The interfaces of the above three motion axles are the same (6Pin, 3.81mm space).
The Axle-X interface is exampled.
Pin Symbols Definitions
1 GND
Kernel power ground (output, only used for common cathode
connection of driver)
2 xDir+
Differential plus end of directional signal
3 xDir-
Differential minus end of directional signal
4 xPulse- Differential minus end of pulse signal (when the common anode
connection is used and the pulse rising edge valid, input will start from
this pin.)
5 xPulse+ Differential plus end of pulse signal (when the common anode
connection is used and the pulse falling edge valid, input will start from
6 +5V
this pin.)
Kernel 5V power positive (output, only used for common anode
connection of driver)
The polarity of directional signal for driver pulse signal can be set. Where a certain
axle is reset, it will move to the opposite direction of machine origin, which means the
polarity of directional signal for this axle is not correct. In such a case, the connection
between this axle and the motor driver can be broken first (otherwise the mainboard can
not be detected to the spacing so as to lead to the collision of this axle), and then such a
polarity can be corrected after this axle is reset completely. Upon the correction, the reset
key can be pressed against to reset the mainboard.
4.11 Laser Power Control Interface CN6/CN7
This control system has two independent and adjustable digital/analog laser power
control interfaces. Signals of the two interfaces are similar and the first digital interface
(CN6) is hereby exampled (6Pin, 3.81mm space):

1 LGND
Laser power 5V ground (output)
2 L-On1- Laser-enabled control interface
1. When the laser is the RF laser, this pin will not be used;
2. When the laser is a glass tube, if the used laser is outputted in the
low-level form, this pin will be connected with the laser power enable
end and used to control the ON/Off of laser.
3 L-On1+ Laser-enabled control interface
1. When the laser is the RF laser, this pin will not be used;
2. When the laser is a glass tube, if the used laser is outputted in the
high-level form, this pin will be connected with the laser power enable
end and used to control the ON/Off of laser.
4 LPWM1+ Power control interface of laser/laser tube
1. When the laser is the RF laser, this pin will not be used;
2. When the laser is a glass tube and the laser power PWM end is
high-leveled, this pin will be connected with the laser power PWM
end and used to control the power of the laser.
5 LPWM1- Power control interface of laser/laser tube
1. When the laser is the RF laser, this pin will be connected with the
laser RF-PWM end;
2. When the laser is a glass tube and the laser power PWM end is
low-leveled, this pin will be connected with the laser power PWM end
