# Flying Bear P905H configuration
# Flying Bear P905H

This configuration is for a P905H with **a single extruder and inductive Z-sensor**. It's been thoroughly tested, and I've tried to make the printer work smoothly, so this configuration is more focused on print quality than speed.
Configuration is based on P905H with **a single extruder and inductive Z-sensor**.

- Use this firmware as a baseline for other P905 modifications.
- Find other notes in the config files by searching for "P905H".
I've tried to adapt original Marlin 1.x limits to Marlin 2.1.x with classical jerk and linear advance enabled.

## Build Instructions
- Get Visual Studio Code and install the "Auto Build Marlin" extension.
- Download the [Marlin source code](//marlinfw.org/meta/download/).
- Copy the two Configuration files from this folder into the 'Marlin' folder (replacing the existing files).
- Open the 'MarlinFirmware' project folder in Visual Studio Code.
- Click the "Auto Build Marlin" button and then the Upload button.
- Don't forget to reset your EEPROM with `M502` and `M500` after flashing.
- Linear advance is working but CPU can not handle high speed (more than 90 mm/s or even less)
- Because P905 has heavy X and even heavier Y mass you should consider lower jerk values compared to other printers
- Turning off linear advance/jerk could let you print faster but you should lower print acceleration to 200 (as it was in manufacturer config)

There are some comments in the code that you can find by "P905H" keyword.
