motor controller with PLICO
Project description
plico_motor
client of a motor controlled under the plico environment
plico_motor is an application to control motors under the plico environment.
Installation
Note: it is recommended, before installing packages, to create a conda environment to work.
conda create --name myenv
To create an environment with a specific python version
conda create --name myenv python=3.7
To activate you environment
conda activate myenv
On server
On the server machine you install plico_motor_server with the following command
pip install plico_motor_server
This command also installs a server configuration file that needs to be modified. The file is located at 'yourLocalPath/plico_motor_server/plico_motor_server/conf/plico_motor_server.conf' and contains ip address and port number of your motor. There are five types of motor indicated with motor1, motor2, motor3, motor4 and motor5: this number is to be used to start the corresponding server.
The plico_motor_server package installs also the client package.
On client
On the client machine
pip install plico_motor
Usage
Customize configuration file
location: 'yourLocalPath/plico_motor_server/plico_motor_server/conf/plico_motor_server.conf' The configuration file can be edited by specifying the characteristics with which you want to set your motors at server start-up (speed, usb_port ...) and specifying the number of motors you want to use (from one to five).
Servers are available for:
- Any motor using the PI GCS communication protocol with serial or USB connection
- Tunable Filter (KURIOS VB1 - Thorlabs) with serial or USB connection
- Filter Wheel (FW102B - Thorlabs) with serial or USB connection
- Newport Picomotor linear actuators
- Standa 8SMC5-USB motor using driver Standa 8smc4-5: standa devices are currently not supported on MacOS X because the installation of the libximc library via pip command does not include the macosx package.
Starting Servers
On the servers machine use the executable
plico_motor_server_n
where n indicates the number of the server you want to start in according to what is declared in the configuration file. If you wish to start all servers included in the configuration file, use the command
plico_motor_start
Using the client module
In a python terminal on the client computer:
from plico_motor import motor
your_motor = motor(ServerHostName, ServerPort, axis)
Usage example
your_motor.home()
your_motor.move_to(1000) #nanometers
your_motor.move_by(-50)
