# Script Name: 3d_printer_restore.sh
#
# Description:
# This script automates the restoration of Klipper 3D printer configuration files
# by backing up the existing configuration directory and replacing it with a fresh
# clone from a specified Git repository. It performs the following steps:
#
#   1. Checks for the existence of the current configuration directory.
#   2. If found, renames it to preserve the original as a backup.
#   3. Creates a new, clean configuration directory.
#   4. Clones the contents of the specified Git repository into the new directory.
#   5. Logs all actions and timestamps to a log file for traceability.
#
# Variables:
#   CONFIG_DIR   - Path to the current printer configuration directory.
#   BACKUP_DIR   - Path to store the backup of the original configuration.
#   REPO_URL     - URL of the Git repository containing the desired configuration.
#   LOG_FILE     - Path to the log file where script activity is recorded.
#
# Usage:
#   Run this script on a system with Git installed and access to the target repo.
#   Ensure that the CONFIG_DIR path and REPO_URL are correctly set before execution.
