4.9 X/Y/Z/U axle Motor Driver Interface AXIS_X~AXIS_U
The interfaces of the above four motion axles are the same. The AXIS-X interface is exampled.

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.
And, the Pulse signal can be falling edge valid or rising edge valid. The default setting is falling
edge valid.
The Pulse signal and the directional signal are all OC outputs. The
Controller must be common anode with the motor driver
4.10 Laser Power Control Interface CN5/CN6
This control system has two independent and adjustable digital laser power control interfaces.
Signals of the two interfaces are similar and the first digital interface (CN5) is hereby exampled:

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.
