# Bambu P1S Notes

## WiFi

If you want to set up WiFi without logging in follow this:

<https://wiki.bambulab.com/en/p1/manual/p1-sd-card-network-configuration-guide>

1. Create a new file on the printer's SD card named `user_wifi.cfg`
2. Add the following contents to `user_wifi.cfg`:

    ```text
    ssid:FruitTest08
    password:wikitest12
    ```

3. Put the SD card back in the printer. It should connect automatically.

## Connecting via LAN mode

- Make sure you open 1990 and 2021 (tcp + udp) in your firewall application.

## Browsing SD card via LAN mode

| Key      | Value               |
| -------- | ------------------- |
| Port     | 990                 |
| User     | bblp                |
| Password | Printer Access Code |

<https://linuxconfig.org/lftp-tutorial-on-linux-with-examples>

1. Install lftp: `sudo dnf install lftp`
2. Start lftp with `lftp`
3. Bookmark your printer with `bookmark add p1s ftps://bblp:<access-code>@<printer ip>`
4. List your bookmarks with `bookmark list`
5. Connect to your printer via the bookmark with `lft p1s`
6. Ignore certificate error with `set ssl:verify-certificate/39:FD:60:8A:46:3B:96:A6:9A:71:72:6E:EA:9E:5A:D2:3A:DE:9B:55 no`
7. Ignore all certificate errors with `set ssl:verify-certificate no`
9.  `ls` and `cd` work as expected. To clear the screen, use `ctrl + L`.
10. Copy files to the host with `get remote-file. -o sample.php`. This will copy to the directory you were in before you ran `lftp`.
11. Copy directories to the host with `mirror -P 10 remote_dir local_dir` where `-P` is the number of parallel transfers.
12. Type `exit` to exit.

## Troubleshooting

### Under Extruding

I've had an issue where prints will look "clumpy" or "rough". This was resolved after a complete
hotend swap. I did some testing on the bad nozzle before replacing it and found it could still
extrude decently but I had to raise the temperature 50-60°C above 220° to get the plastic flowing
well. I don't think the ceramic heater was broken since the nozzle was clearly heating just fine.
This leads me to believe the thermistor went bad or became disconnected from the nozzle somehow. My
guess is Bambu didn't use enough thermal compound at the factory and it became dry and cracked,
creating a layer of air between the thermistor and the nozzle.
