PETG Settings for Artillery X4 Pro S1

Temperature Settings

Start with the nozzle at 240°C and the bed at 85°C. If you see poor layer adhesion, increase the nozzle temperature by 5°C increments. If you experience stringing, decrease the nozzle temperature by 5°C. For the first layer, you can increase the bed temperature by 5°C for better adhesion, then let it drop back to 85°C for subsequent layers.

The PETG filament has a recommended nozzle temperature range of 230-250°C and a bed temperature range of 80-90°C. The Artillery X4 Pro S1 supports nozzle temperatures up to 300°C and bed temperatures up to 110°C, which fully covers the recommended range for this filament.

Speed & Quality

The Artillery X4 Pro S1 supports high-speed printing at up to 500 mm/s. For PETG, we recommend 60-150 mm/s for general printing. Start with the lower end for quality-critical prints and increase for draft prints. Always print the first layer at 25-50% of your normal speed for better adhesion.

For quality-critical prints like miniatures or display pieces, reduce the speed to 60 mm/s and use a 0.12-0.16mm layer height. For draft or rapid prototyping, you can push the speed to 150 mm/s with a 0.24-0.28mm layer height. The standard 0.2mm layer height at 105 mm/s provides the best balance of speed and quality for most prints.

Bed Adhesion

PETG bonds extremely well to smooth PEI sheets -- sometimes too well. Use a textured PEI sheet or apply a thin layer of glue stick as a release agent on smooth PEI to prevent damage. On glass beds, always use glue stick (PETG can pull glass chips off). Let the bed cool completely before removing prints.

Common Issues with PETG on Artillery X4 Pro S1

Here are the most common problems you may encounter when printing PETG on the Artillery X4 Pro S1, along with proven solutions:

• Excessive stringing: Reduce temperature to 230-235°C, increase retraction speed to 60 mm/s, and dry the filament
• Foggy or rough surface: Reduce fan speed to 30% and increase temperature slightly
• Sticking too hard to bed: Let the bed cool completely before removal; use glue stick as release agent on PEI
• Brittle prints: Likely moisture-damaged; dry at 65°C for 6-8 hours

Tips for Best Results

Follow these expert tips to get the best possible prints with PETG on your Artillery X4 Pro S1:

• Dry your PETG before printing -- even a new spool left open overnight can absorb enough moisture to affect quality
• Slow down the first layer to 15-20 mm/s for solid adhesion
• Use a lower fan speed (30-50%) -- too much cooling weakens layer adhesion with PETG
• If printing on smooth PEI, use glue stick as a release agent to prevent bed damage
• PETG is an excellent all-around material once you dial in the settings

Support Settings

For prints requiring supports with PETG, use tree supports for easier removal and less scarring. Set a 0.15-0.2mm Z-distance between support and model. If you have a dual-extruder setup, consider PVA (for PLA/PETG) or HIPS (for ABS) as dedicated water/solvent-soluble support material.
