Saving and Loading Files

The RTMC130 system uses various file types to store your movements, configuration settings, and other important data. Proper file management is crucial for maintaining your work and ensuring consistent operation across sessions.

Remember: The RTMC130 operates in an MS-DOS environment with file naming constraints. Filenames are limited to 8 characters with a 3-character extension (8.3 format). Save your work frequently to prevent loss due to system crashes or power failures.

Understanding File Types

The RTMC130 system uses several distinct file types, each serving a specific purpose:

File Type Extension Contains When to Use
Move Files .MOV Movement data, keyframes, and paths To save a specific movement sequence
Setup Files .SET System configuration, axis settings, motor patches To save hardware configuration settings
Environment Files .ENV Overall system preferences To save global system settings
Temporary Files .TMP Temporary move storage For quick save/restore operations
ASCII Files .ASC Text-based move data For importing/exporting to other systems

Default System Files

The RTMC130 system automatically looks for these important default files:

  • DEFAULT.SET - Loaded automatically at startup if present
  • RTMC.ENV - Contains environment variables and global settings
  • LASTMOVE.MOV - Auto-saved version of the most recent move (for recovery)

Tip: After configuring your system to your preferences, always save a DEFAULT.SET file. This will ensure the system returns to your preferred configuration each time you start the software.

Saving Movements

After creating a movement sequence, saving it is essential to preserve your work for future use.

Saving a Move File

  1. From the main Control Panel, click UtilFiles
  2. Select Save Move from the menu
  3. The Save Move dialog will appear
  4. Enter a filename (up to 8 characters, no extension needed)
  5. Optionally, add a description of the move when prompted
  6. Press Enter to save
  7. The system will save the file with a .MOV extension

Quick Temporary Save

For quick saves during work sessions:

  1. From the main Control Panel, click UtilFiles
  2. Select Save Temp from the menu
  3. The move will be saved with an automatically assigned temporary name

Keyboard Shortcut: Type st (Save Temp) followed by Enter at the main Control Panel for a quick temporary save.

Naming Conventions

Due to the 8-character limit, develop a consistent naming scheme:

  • Project Prefixes: Use 2-3 letter prefixes for projects (e.g., CM_ for "Commercial")
  • Version Numbers: Include version numbers (e.g., ORBIT_01, ORBIT_02)
  • Move Types: Indicate move type (e.g., PAN_ORBT for a panning orbit)
  • Descriptive: Make names descriptive within the constraints (e.g., DOLLY_IN)

Important: The system will overwrite existing files with the same name without warning. Always use unique filenames or verify before saving with an existing name.

Loading Movements

Loading previously saved movements allows you to reuse your work or continue editing from a previous session.

Loading a Move File

  1. From the main Control Panel, click UtilFiles
  2. Select Load Move from the menu
  3. The Load Move dialog will appear showing available move files
  4. Use the arrow keys to navigate through the file list
  5. Press Enter to select the highlighted move
  6. The move will be loaded into memory, replacing any current move data

Restoring a Temporary Save

  1. From the main Control Panel, click UtilFiles
  2. Select Load Temp from the menu
  3. The system will display available temporary saves
  4. Select the desired temporary file to load

Keyboard Shortcut: Type lt (Load Temp) followed by Enter at the main Control Panel to quickly load the most recent temporary save.

Before Loading a Move

Take these precautions before loading a move file:

  • Save Current Work: If you have unsaved changes, save them first
  • Check Configuration: Ensure your hardware configuration matches the one used when the move was created
  • Verify Space: Make sure the physical space is clear for the movement that will be loaded
  • Initial Test: After loading, run the move at low speed first to verify it behaves as expected

Safety Warning: Loading a move and immediately running it at full speed can be dangerous if the move requires more physical space than is available or uses different axis assignments than your current setup.

Saving System Configurations

Setup files store your hardware configuration, including motor patches, axis settings, and calibration values. Saving these settings is crucial for maintaining consistent system behavior.

Saving a Setup File

  1. Configure your system as desired:
    • Set axis parameters in AxisSetup
    • Configure motor patching (see Motor Patching)
    • Adjust any other hardware settings
  2. From the main Control Panel, click UtilFiles
  3. Select Save Setup from the menu
  4. Enter a filename (up to 8 characters)
  5. Press Enter to save
  6. The system will save the file with a .SET extension

Saving the Default Setup

To create a configuration that loads automatically at startup:

  1. Configure your system as desired
  2. From the main Control Panel, click UtilFiles
  3. Select Save Default Setup from the menu
  4. The system will save the configuration as DEFAULT.SET

Multiple Machine Configurations: If you use your system with different physical configurations, create separate setup files for each (e.g., CRANE.SET, DOLLY.SET).

Loading a Setup File

  1. From the main Control Panel, click UtilFiles
  2. Select Load Setup from the menu
  3. The Load Setup dialog will appear showing available setup files
  4. Select the desired setup file
  5. Press Enter to load
  6. The system will apply the configuration immediately

Important: Loading a setup file changes your axis calibrations and motor patching immediately. This can cause unexpected movement if motors are powered. Consider disabling motor drivers before loading a new setup.

File Management

Proper file management is essential for maintaining an organized workflow and preventing data loss.

Viewing File Directories

  1. From the main Control Panel, click UtilFiles
  2. Select View Moves to see all move files or View Setups to see setup files
  3. Use arrow keys to navigate through the list
  4. Press ESC to return to the menu

Copying and Backing Up Files

Regular backups are crucial. To copy files to a backup disk:

  1. Exit the RTMC130 software to return to DOS
  2. Use DOS commands to copy files:
    COPY *.MOV A:
    COPY *.SET A:
  3. Or use a backup utility if available

File Management Best Practices

  • Regular Backups: Back up important moves and setups to external media regularly
  • Version Control: Use incrementing version numbers for iterative work
  • Documentation: Keep a written log of important file details and settings
  • Clean-up: Periodically remove obsolete files to prevent clutter
  • Organization: Group related files using consistent naming conventions

Tip: At the end of each project, create an archive folder on a separate drive with all the related move and setup files. Label it clearly with the project name and date.

Recovering Lost Files

If you experience a crash or power failure:

  1. Upon restarting, use the rq (Reload Quit) command at the main prompt
  2. This will attempt to recover data from the last session
  3. If successful, immediately save the recovered data with a new name

Important: Recovery is not always possible after a crash. This reinforces the importance of frequent saving during your work sessions.
