Community Reviews & Feedback

Positive Aspects:

• Extremely stable and precise large-format printing
• Dual-tool system enables clean multi-material prints
• Excellent for engineering parts and prototypes
• Open-source ecosystem with deep customization
• Reliable auto-calibration and tool alignment

Areas for Improvement:

• Large footprint requires significant workspace
• Tool changes are slower than AMS-style systems
• High price point compared to smaller multi-color printers
• TPU requires careful tuning on dual-tool setups

🎯 Best Practices for Prusa XL (Dual-Tool)

Initial Setup

1. Run full auto-calibration and tool alignment
2. Verify nozzle heights for both toolheads
3. Update firmware before first print
4. Print the official dual-tool calibration model
5. Check toolchanger latch tension

Daily Maintenance

• Clean the large PEI sheet before each print
• Inspect toolchanger mechanism weekly
• Lubricate linear rails monthly
• Check toolhead parking docks for debris
• Monitor purge volumes for multi-material jobs

Material Handling

• PLA, PETG, ABS, ASA all print well
• TPU requires slow speeds and direct drive toolhead
• Use filament with consistent diameter for best toolchanging reliability
• Dry filament improves multi-material performance

🖥️ Recommended Slicers

The Prusa XL works best with:

• PrusaSlicer (Official): Full dual-tool integration
• SuperSlicer: Advanced tuning for power users

⚙️ Optimal Slicer Settings

General Quality Settings

Setting	Recommended Value	Notes
Layer Height	0.2mm (standard), 0.1mm (high detail)	Large-format prints benefit from thicker layers
Print Speed	80–150 mm/s	Reduce to 60 mm/s for multi-material
Travel Speed	200 mm/s	Helps reduce stringing
Retraction Distance	0.6–1.0 mm	Direct drive extruders
Retraction Speed	35–45 mm/s	Prevents blobs during tool changes

Curved Top Surfaces

• Enable ironing for PLA
• Ironing speed: 20–35 mm/s
• Top layers: 6–8

Minimizing Layer Lines

• Enable Input Shaper
• Use adaptive layer height
• Use “Random” seam for organic models

Support Settings

Setting	Recommended Value
Support Type	Organic or Snug
Overhang Angle	55°
Support Density	10–12%
Top Distance	0.25 mm

🔧 Calibration Guide

Bed Leveling

1. Heat bed to 60°C
2. Run auto-leveling
3. Verify with paper test
4. Adjust Z-offset if needed

Toolhead Calibration

1. Run automatic tool alignment
2. Verify nozzle heights manually
3. Check toolchanger latch tension
4. Print dual-color calibration cube

Temperature Calibration

• PLA: 200–215°C
• PETG: 235–250°C
• ABS/ASA: 245–260°C

Flow Rate Calibration

1. Print single-wall cube
2. Measure wall thickness
3. Adjust flow until accurate

⚠️ Common Issues & Solutions

Toolhead Misalignment

• Re-run tool alignment wizard
• Check tool dock cleanliness
• Verify nozzle height offsets

Stringing

• Increase travel speed
• Lower temperature by 5–10°C
• Enable combing

Under-Extrusion

• Check extruder tension
• Dry filament thoroughly
• Increase flow by 2–5%

Warping (Large Prints)

• Use brims or rafts
• Increase bed temperature
• Use enclosure add-ons for ABS/ASA

📊 Material-Specific Recommendations

PLA

• 200–210°C nozzle, 60°C bed
• Great for multi-material prints
• Brands: Prusament, eSun, Overture

PETG

• 240–250°C nozzle, 80°C bed
• Reduce speed to avoid stringing

ABS / ASA

• 245–260°C nozzle, 100°C bed
• Use enclosure for best results

TPU

• Use direct drive toolhead
• Print at 20–30 mm/s
• Not recommended for dual-tool mixing
