For interactive jog mode:

pip install "one-axis-stage[cli]"

Quick start

from one_axis_stage.api import StageAPI

api = StageAPI(serial_port="/dev/ttyUSB0")
api.connect()
print(api.get_info(device_id=21))
api.set_position(device_id=21, position=400)
api.disconnect()

CLI

stage scan --port /dev/ttyUSB0
stage info --port /dev/ttyUSB0 --id 21
stage move --port /dev/ttyUSB0 --id 21 --position 400
stage jog  --port /dev/ttyUSB0 --id 21
