This Python 3 package is for controlling a (custom) scanner, which uses two SCX11 universal controllers and stepping motors.
Only serial connection is supported.
The package enables easy connectivity and creation of concurrent control scripts for the motors.
Move scanner to two user defined positions.
from scx11scanner.scanner import Scanner
# Specify serial ports
scan = Scanner(x_motor='COM5', y_motor='COM4', log_path='log.log')
with scan.open() as s:
s.calibrate() # Moves scanner to max position and sets HOME position
s.move_pos(x=50, y=50)
s.move_pos(x=25, y=25)
# Both motors start moving immediately and block execution until the movement is finished.Note
move_pos() function requires calibration or at least reset_home() to set (x=0, y=0) position for the motors.
Otherwise, use move_up(), move_down(), move_left(), move_right() or Motor() class' methods directly.
Warning!
Use calibrate() to move scanner/motor to maximum position ONLY if there is an mechanism to stop motor movement at maximum position with outside alerting signal.
Individual motors can also be controlled separately from the Scanner().
from scx11scanner.scanner import Motor
motor = Motor()
with motor.open as m:
s.move(dis=10) # Specify moving distance if HOME position is not set.
s.move(dis=-10)Tested only with Python 3.5 (Windows), but underlying PySerial module should support linux also.
pip install <directory path to setup.py>
