Polish Logging Output for Production Multi-Material Printing

Status

✅ Multi-material printing system is now fully functional!

After extensive troubleshooting, the system successfully:

• Detects material changes at correct layers (1, 2, 3)
• Executes pump operations (drain→fill→mix→settle) with detailed logging
• Coordinates bed positioning and pause/resume workflow
• Processes A→B→C material transitions correctly

Current Output Quality

The system produces excellent research-focused logs with proper categorization:

• PROGRESS: Layer progress updates
• MATERIAL: Material change start/completion with timing
• TIMING: Detailed bed positioning and pump sequence steps
• EXPERIMENT: Experiment start/end summary

Identified Improvements

High Priority (Quick Wins)

1. Clean up startup logging - consolidate redundant PRINT messages during initialization
2. Fix goresume warning display - change "ERROR: unrecognized command: goresume" to INFO level (expected behavior)
3. Reduce status polling noise - decrease frequency of AUTO: Status: PAUSE messages during material changes

Medium Priority (Nice to Have)

4. Add experiment summary - total time, materials used, changes completed
5. Material usage tracking - cumulative volumes per material (A: 45ml, B: 45ml, etc.)
6. Better progress indicators - show pump operation progress during long sequences

Low Priority (Future Enhancement)

7. Pump timing optimization - research faster material change sequences
8. Advanced error recovery - handle edge cases and failures gracefully
9. Remote monitoring - API for external monitoring systems

Example Current Output

[01:00:39] MATERIAL: Change #1: Layer 1 → Material A
[01:00:39] TIMING: Step 1: Pausing printer...
[01:00:39] TIMING: Step 2: Waiting for bed to reach raised position...
[01:00:39] TIMING: Step 3: Starting pump sequence...
[01:00:39] PRINT: Running Drain Pump: 50ml at 5.0ml/s (10.0s)
[01:00:39] PRINT: Running Pump A: 45ml at 2.5ml/s (18.0s)
[01:00:39] MATERIAL: Change #1 completed in 63.7s

Implementation Notes

• System is production-ready as-is
• Improvements are polish rather than functionality fixes
• All changes should maintain research-friendly logging format
• Keep backward compatibility with existing GUI parsing

Files Involved

• src/controller/print_manager.py - main logging coordination
• src/controller/mmu_control.py - pump operation logs
• src/controller/printer_comms.py - goresume warning source
• src/gui/dialog.cpp - GUI log parsing (may need updates)

Testing

Any changes should be tested with:

1. Complete A→B→C material change sequence
2. GUI log parsing and display
3. Research log file generation
4. Error condition handling
