The grating drive board (digital drive card) converts digital instructions from the host computer into high-precision current/voltage, and is equipped with a grating motor,

Read the signal from the grating encoder, measure the angle in real time, and the FPGA performs PID calculations and dynamically corrects deviations, achieving a positioning accuracy of 10 urad;

Achieve micro-radian level positioning and precisely control the high-speed scanning of the laser beam on the XY plane.

Purpose: high-precision laser marking/engraving, laser drilling/micro-machining, laser medical aesthetics/scanning, 3D printing/laser projection, etc.
