## Configuration
Start with the [Positron3D Prusawire Configuration](https://github.com/Positron3D/prusawire-klipper-config) settings and profiles.
More detail general instructions are found at [Software Configuration \| Voron Documentation](https://docs.vorondesign.com/build/software/configuration.html).
### Sensorless Homing
If you are running the Einsy board, congrats, you are now done.
For the BTT SKR Mini E3, some further tuning likely needs to happen. Refer to [this guide](https://gist.github.com/clee/9108f7717defce8b1222698f816def0a#finding-the-right-stallguard-threshold) by clee on setting the correct stallguard threshold.
### Input Shaper
Some defaults have been provided, but they are no doubt unsuitable for your exact machine. We recommend installing [ShakeTune](https://github.com/Frix-x/klippain-shaketune) for measuring resonances, and reading the [Klipper guide](https://www.klipper3d.org/Measuring_Resonances.html#max-smoothing) on understanding which value to choose.
**Y Axis Input Shaping**: This requires an external accelerometer (eg LDO Input Shaper) to be mounted to your heated bed.

```
- `cd ~/printer_data/config/prusawire/`
- `cp printer.cfg.example ../printer.cfg`
- `cd ~/printer_data/config/`
- Edit `printer.cfg`:
- Uncomment the correct section for the control board you're using.

## SuperPINDA Probe
Brown = +5V
Blue = GND
Black = Signal
### NiteHawb-SB
Make sure there isn't a "!" in the superpinda config or it won't work.
```
[probe]
pin: ^nitehawk:gpio13
```
On NiteHawk-SB, use the XY Endstop Port. Connect Black(Signal) to GPIO13.

### ShakeTune - Input Shaping
Usage Documentation: [klippain-shaketune/docs/README.md at main · Frix-x/klippain-shaketune · GitHub](https://github.com/Frix-x/klippain-shaketune/blob/main/docs/README.md)
1. Be sure to have a working accelerometer on your machine and a `[resonance_tester]` section defined. You can follow the official [Measuring Resonances Klipper documentation](https://www.klipper3d.org/Measuring_Resonances.html) to configure it.
2. Install Shake&Tune by running over SSH on your printer:
```shell
wget -O - https://raw.githubusercontent.com/Frix-x/klippain-shaketune/main/install.sh | bash
```
3. Then, append the following to your `printer.cfg` file and restart Klipper:
```
[shaketune]
# result_folder: ~/printer_data/config/ShakeTune_results
# Path where the processed results will be stored. If the folder doesn't exist,
# it will be automatically created. You can change this if you'd like to store
# results in a different location.
# number_of_results_to_keep: 10
# This setting defines how many results you want to keep in the result folder.
# Once the specified number is exceeded, older results will be automatically deleted
# to free up space on the SD card and avoid cluttering the results folder.
# keep_raw_data: False
# If set to True, Shake&Tune will store both the processed graphs and the raw accelerometer
# .stdata files in the results folder. This can be useful for debugging or archiving purposes.
# Please always attach them when reporting any issues on GitHub or Discord.
# show_macros_in_webui: True
# Mainsail and Fluidd doesn't create buttons for system commands (macros that are not part
# of the printer.cfg file). This option allow Shake&Tune to inject them into the webui at runtime.
# If set to False, the macros will be hidden but still accessible from the console by typing
# their names manually, which can be useful if you prefer to encapsulate them into your own macros.
# timeout: 600
# This defines the maximum processing time (in seconds) to allows to Shake&Tune for generating
# graphs from a .stdata file. 10 minutes should be more than enough in most cases, but if you have
# slower hardware (e.g., older SD cards or low-performance devices), increase it to prevent timeouts.
# measurements_chunk_size: 2
# Each Shake&Tune command uses the accelerometer to take multiple measurements. By default,
# Shake&Tune will write a chunk of data to disk every two measurements, and at the end of the
# command will merge these chunks into the final .stdata file for processing. "2" is a very
# conservative setting to avoid Klipper Timer Too Close errors on lower end devices with little
# RAM, and should work for everyone. However, if you are using a powerful computer, you may
# wish to increase this value to keep more measurements in memory (e.g., 15-20) before writing
# the chunk and avoid stressing the filesystem too much.
# max_freq: 200
# This setting defines the maximum frequency at which the calculation of the power spectral density
# is cutoff. The default value should be fine for most machines and accelerometer combinations and
# avoid touching it unless you know what you're doing.
# dpi: 300
# Controls the resolution of the generated graphs. The default value of 300 dpi was optimized
# and strikes a balance between performance and readability, ensuring that graphs are clear
# without using too much RAM to generate them. Usually, you shouldn't need to change this value.
