12-Hour Filament (PETG/ASA/ABS) Drying GCode for Bambu Lab P1S

## 🚨 CRITICAL MATERIAL WARNING 🚨
This drying profile is ONLY suitable for:
- PETG
- ASA
- ABS

### ⛔ DO NOT USE WITH PLA ⛔
The bed temperature of 80°C will DAMAGE PLA filament!
- PLA begins to fuse at temperatures above 60°C
- Using this profile with PLA will result in a fused/ruined filament spool
- For PLA, use a dedicated PLA drying profile with lower temperatures

## ⚠ Important Safety Warning ⚠
Always wait for the Z-axis (heated bed) to complete its downward movement to the bottom of the print volume before placing your filament roll. This prevents any potential collision between the bed and your filament spool.

## What You'll Need
- Your Bambu Lab P1S printer (X1 Machines have a buildin drying Tool)
- SD card from your printer
- Computer with SD card reader
- PETG, ASA, or ABS filament that needs drying
- Small piece of paper/cardboard to place under the filament spool (optional but recommended)

## Preparation Steps

### 1. Downloading the G-code
- Download the filament drying G-code file from this page
- Remember where you saved it (usually in your Downloads folder)

### 2. Accessing Your SD Card
- Turn off your Bambu printer
- Remove the SD card from your printer
- Insert the SD card into your computer's card reader or USB adapter

### 3. File Transfer Process
1. Open File Explorer/Finder on your computer
2. Open TWO windows:
  - First window: Navigate to your Downloads folder where the G-code is
  - Second window: Navigate to your SD card → Models folder
3. Copy or drag the filament drying G-code file from Downloads to the Models folder
4. Safely eject the SD card from your computer

### 4. Printer Setup
1. Insert the SD card back into your Bambu printer
2. Power on the printer
3. The drying G-code will appear in your printer's file menu

## Running the Drying Process

### Safety Steps (VERY IMPORTANT)
1. Start the G-code
2. Wait for initial homing (G28)
3. Wait for the heated bed to move completely down
4. **ONLY AFTER** the bed is fully lowered, place your filament roll on it

### Process Details
- Total drying time: 12 hours
- Bed temperature: 80°C (Suitable for PETG/ASA/ABS ONLY)
- Chamber fan settings:
 - Initial 70% for warmup
 - Reduces to 40%
 - Finally settles at 30% for main drying cycle

### Tips for Best Results
- Place filament spool flat on the heated bed
- Consider placing a small piece of paper/cardboard under the spool to prevent any potential sticking
- Make sure the filament can rotate freely
- Keep the printer door closed during the process
- Room temperature should be stable (avoid placing printer near AC/heating vents)

## ⚠ Warning Signs - Stop the Process If:
- You hear any unusual noises
- The filament spool appears to be deforming
- The printer displays any error messages
- Chamber temperature seems unusually high

## After Drying
1. Wait for the process to complete (12 hours)
2. The bed will automatically turn off
3. Wait for the bed to cool before removing your filament
4. Store dried filament in a sealed bag with desiccant if not using immediately

Remember: Always monitor the first few minutes of the process to ensure everything is working as expected.
