3D scanner (lidar, ultrasonic) v2

This is concept of cheap 3D scanner with lidar ( http://www.benewake.com/en/tfmini.html ).
I use Arduino Nano with CNC shield + A4988 driver for stepper motor.
Scanner write position (x,y,z) to SD card.
buttons for home H(orizontal), for home V(ertical), scan and stop(not working yet).

for now:
this is first test build.
NOT work microstep, so 1 step is 1,8° (not good for scanner-working on)
lidar accuracy is not acceptable - see video
UPDATE:
modify for change lidar or ultrasonic senor.
enabled multistep on driver(shield has wrong wiring...)
