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

Create a new file on the printer's SD card named user_wifi.cfg
Add the following contents to user_wifi.cfg:
```
ssid:FruitTest08
password:wikitest12
```
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.

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.
