🚀 Start G-Code Scripts

Universal Start (Ender3V2-Sprite-Start.gcode)

Uses Cura slicer variables ({material_bed_temperature_layer_0} etc.) so temperatures are pulled automatically from your slicer profile. Use this as your default in Cura for maximum flexibility across materials.

Sequence:

1. Pre-heat nozzle to 150°C (softens residual filament, no ooze)
2. Heat bed to slicer material temperature
3. Home all axes
4. Run UBL 4-point quick tilt correction + load mesh slot 0
5. Fade mesh correction over 5mm
6. Move to prime position
7. Heat nozzle to print temperature
8. Double prime line (relative extrusion — easy to tune)
9. Reset and prepare for print
10. Beep notification

---

PLA Start (Start-PLA.gcode)

Hardcoded for PLA at 210°C nozzle / 60°C bed. Use this when you want explicit control rather than relying on slicer variables.

Key PLA settings:

Setting	Value
Nozzle temp	210°C (215°C for PLA+)
Bed temp	60°C
Fan	100% from layer 2
Retraction	1mm @ 45mm/s
First layer speed	25mm/s

---

ABS Start (Start-ABS.gcode)

Designed for the enclosed heated cabinet build. Includes a 3-minute enclosure heat soak before homing to ensure thermal stability and prevent warping.

Key ABS settings:

Setting	Value
Nozzle temp	240°C (245°C for ASA)
Bed temp	100°C (105°C for ASA)
Chamber temp	45–50°C minimum
Fan	0–20% max
Retraction	1mm @ 45mm/s
First layer speed	20mm/s
Heat soak	3 minutes (adjust to taste)

⚠️ ABS requires the enclosure to be closed during the entire print. Opening it causes thermal shock which leads to warping and layer delamination.

---

🏁 End G-Code Scripts

Universal End (Ender3V2-Sprite-End.gcode)

Works with any material. Retracts 1mm (appropriate for Sprite direct drive), presents the print, cools down, and disables motors.

PLA End (End-PLA.gcode)

Runs a brief full-fan blast after print completion to speed up cooling, then shuts everything down.

ABS End (End-ABS.gcode)

Slow cool sequence — critical for ABS to prevent warping:

1. Fan stays OFF
2. Bed holds at 60°C for 5 minutes
3. Then bed turns off completely
4. Double beep reminds you to wait before opening the enclosure

⏳ Wait 15–20 minutes after the print finishes before opening the enclosure.

⚙️ Firmware Configuration (Ender2V2SpriteConfigurationFile.gcode)

Applied directly to the printer via SD card. Sets up:

Setting	Value	Notes
Brightness	150	M256 B150
Power loss recovery	Enabled	M413 S1 — resumes print after power outage
Filament change	200mm load/unload	M603 L200 U200
Probe feedrate	800mm/min	C851 S800
Mesh insets	5mm all sides	C29 L25 R195 F25 B195
Mesh size	5x5 grid	N5
Mesh bed temp	50°C	T50 — matches PLA bed temp
Bed dimensions	220x220mm	C102 X220 Y220
Build volume	230x230x240mm	C101 X230 Y230 Z240
Filament sensor	Active LOW	C412 M0

💡 Tip: For ABS printing, change T50 to T100 in the mesh command so leveling happens at ABS bed temperature for more accurate compensation.

🎨 Display Themes

Apply themes via SD card. Each file sets the LCD colour scheme and saves to EEPROM.

Theme	Description
Default	Stock Creality green
Blue	Cool blue tones
Grey	Neutral grey
Purple	Deep purple
Red	Warm red

To apply a theme:

1. Copy the theme .gcode file to the root of an SD card
2. Insert into printer and print the file
3. The printer will apply colours, save to EEPROM, and reboot

🔧 How to Use in Cura

Universal Scripts (recommended)

1. Open Cura → Printer Settings → Machine Settings
2. Paste contents of Ender3V2-Sprite-Start.gcode into Start G-code
3. Paste contents of Ender3V2-Sprite-End.gcode into End G-code

Material-Specific Scripts

1. Create separate printer profiles in Cura for PLA and ABS
2. Use Start-PLA.gcode / End-PLA.gcode in the PLA profile
3. Use Start-ABS.gcode / End-ABS.gcode in the ABS profile

💡 Key Improvements Over Stock G-Code

Issue	Old Behaviour	Improved Behaviour
Nozzle pre-heat	Cold during homing	150°C during homing (softens residual filament)
UBL fade height	10mm	5mm (correction where it matters)
Retraction	4mm total	1mm + 1mm (correct for Sprite direct drive)
Prime line travel	Z0.03 (dangerous)	Z0.2 travel → Z0.3 prime
Prime extrusion	Absolute (harder to tune)	Relative (easy to tune)
Motor disable	Instant	2 second delay (prevents bed drop)
ABS cooling	Immediate shutdown	Slow cool with bed hold at 60°C
Enclosure heat soak	None	3-minute soak before homing

---

⚠️ Important Notes

• Sprite Direct Drive — retraction should be 1–2mm maximum. More causes grinding and clogs
• UBL Mesh Slot 0 — these scripts load mesh slot 0 (G29 L0). If you save your mesh to a different slot, update this value
• Power Loss Recovery — enabled (M413 S1) in all start scripts and configuration file. The printer will resume a print automatically after a power outage
• ABS Ventilation — ABS fumes are hazardous. Route enclosure ventilation outside your workspace, not into the room
• Heat Soak Time — the 3-minute ABS heat soak (G4 S180) may need adjusting based on your cabinet's insulation quality
