## Activate button and led support

[Raspberry Pi Power-Up and Shutdown with a Physical Button](https://embeddedcomputing.com/technology/open-source/development-kits/raspberry-pi-power-up-and-shutdown-with-a-physical-button)
|
||
|
||
|
||
### TL;DR
|
||
|
||
#### Add button support
|
||
|
||
1. Edit `/boot/config.txt` file.
|
||
2. Add line ` dtoverlay=gpio-shutdown`.
|
||
|
||
Final result:
|
||
```
|
||
[...]
|
||
|
||
[all]
|
||
# enable raspicam
|
||
start_x=1
|
||
gpu_mem=128
|
||
|
||
# Simple button on/off
|
||
dtoverlay=gpio-shutdown
|
||
```
|
||
|
||
#### Add LED support
|
||
|
||
1. Edit crontab
|
||
```
|
||
#> crontab -e
|
||
```
|
||
|
||
|
||
2. Add the line
|
||
```
|
||
@reboot raspi-gpio set 4 op dh
|
||
```
|
||
|
||
Final result:
|
||
```
|
||
# Edit this file to introduce tasks to be run by cron.
|
||
#
|
||
# Each task to run has to be defined through a single line
|
||
# indicating with different fields when the task will be run
|
||
# and what command to run for the task
|
||
#
|
||
# To define the time you can provide concrete values for
|
||
# minute (m), hour (h), day of month (dom), month (mon),
|
||
# and day of week (dow) or use '*' in these fields (for 'any').
|
||
#
|
||
# Notice that tasks will be started based on the cron's system
|
||
# daemon's notion of time and timezones.
|
||
#
|
||
# Output of the crontab jobs (including errors) is sent through
|
||
# email to the user the crontab file belongs to (unless redirected).
|
||
#
|
||
# For example, you can run a backup of all your user accounts
|
||
# at 5 a.m every week with:
|
||
# 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/
|
||
#
|
||
# For more information see the manual pages of crontab(5) and cron(8)
|
||
#
|
||
# m h dom mon dow command
|
||
@reboot raspi-gpio set 4 op dh

I upgraded my Ender 3 printer with [BIGTREETECH SKR MINI E3 V2](https://www.aliexpress.com/item/4001050145015.html) mainboard.
|
||
|
||
Firmware above is built for this mainboard!
|
||
|
||
|
||
## Installed firmware
|
||
|
||
- Currently used tag: [`2.1.2.4`](https://github.com/MarlinFirmware/Marlin/tree/2.1.2.4)
|
||
- Details: [Firmware sources and custom configuration](./Marlin-2.1.2.4/) (local repo)
|
||
- Last compilation date: `2024-10-10 @ 09:53`
|
||
|
||

# Printer calibration:
|
||
|
||
After firware update, proceed with the different calibrations in the above order:
|
||
|
||
1. **[Z-Offset Wizard – A Complete Guide](https://3dprintscape.com/z-offset-wizard-complete-guide/)** \
|
||
On my custom firware, you can use the `Z Probe Wizard` feature to help performing the Z-Offset. \
|
||
To do so, on Ender 3 screen menu, select : `Motion > Z Probe Wizard`.
|
||
2. **Bed leveling** \
|
||
To have a printer bed properly leveled when you make changes to the printer, here the list of operations to be done in that exact order. \
|
||
Both bed tramming and ABL require a BLTouch (or equivalent) hardware. See [3D printed custom parts & mods](#3d-printed-custom-parts--mods).:
|
||
1. Do a **bed tramming** (a.k.a manual bed leveling). On Ender 3 screen menu, select: `Motion > Tramming Wizard`.
|
||
2. Do an **automatic bed leveling (ABL)**.
|
||
In Octoprint, go to [Bed Visualizer](https://plugins.octoprint.org/plugins/bedlevelvisualizer/) plugin UI and click `Update Mesh Now` button.
|
||
3. **[Marlin PID Auto-Tune - A Complete Guide](https://3dprintinggeek.com/marlin-pid-tuning/)**
|
||
- :warning: First do the PID Auto-Tune for the **bed**. Else you may have false positive thermal runout.
|
||
4. **Linear Advance (also know as Pressure Advance)** \
|
||
Linear advance tunning is filament specific. \
|
||
For a given brand & type (PLA, PETG), you **may** use the same LA tunning. \
|
||
But for optimal result you should tune PA for each filament roll.
