+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at [marlinfirmware@github.com](mailto:marlinfirmware@github.com). All complaints will be reviewed and investigated and will result in a response that is deemed necessary and appropriate to the circumstances.

+
+Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4, available at [https://contributor-covenant.org/version/1/4][version]

+  * Other channels exist for certain topics. Check the channel list.
+
+## How Can I Contribute?
+
+### Reporting Bugs
+
+This section guides you through submitting a Bug Report for Marlin. Following these guidelines helps maintainers and the community understand your report, reproduce the behavior, and find related reports.
+
+Before creating a Bug Report, please test the "nightly" development branch, as you might find out that you don't need to create one. When you are creating a Bug Report, please [include as many details as possible](#how-do-i-submit-a-good-bug-report). Fill out [the required template](issue_template.md), the information it asks for helps us resolve issues faster.
+
+> **Note:** Regressions can happen. If you find a **Closed** issue that seems like your issue, go ahead and open a new issue and include a link to the original issue in the body of your new one. All you need to create a link is the issue number, preceded by #. For example, #8888.
+
+#### How Do I Submit A (Good) Bug Report?
+
+Bugs are tracked as [GitHub issues](https://guides.github.com/features/issues/). Use the New Issue button to create an issue and provide the following information by filling in [the template](issue_template.md).
+
+Explain the problem and include additional details to help maintainers reproduce the problem:
+
+* **Use a clear and descriptive title** for the issue to identify the problem.
+* **Describe the exact steps which reproduce the problem** in as many details as possible. For example, start by explaining how you started Marlin, e.g. which command exactly you used in the terminal, or how you started Marlin otherwise. When listing steps, **don't just say what you did, but explain how you did it**. For example, if you moved the cursor to the end of a line, explain if you used the mouse, or a keyboard shortcut or an Marlin command, and if so which one?
+* **Provide specific examples to demonstrate the steps**. Include links to files or GitHub projects, or copy/pasteable snippets, which you use in those examples. If you're providing snippets or log output in the issue, use [Markdown code blocks](https://help.github.com/articles/markdown-basics/#multiple-lines).
+* **Describe the behavior you observed after following the steps** and point out what exactly is the problem with that behavior.
+* **Explain which behavior you expected to see instead and why.**
+* **Include detailed log output** especially for probing and leveling. See below for usage of `DEBUG_LEVELING_FEATURE`.
+* **Include screenshots, links to videos, etc.** which clearly demonstrate the problem.
+* **Include G-code** (if relevant) that reliably causes the problem to show itself.
+* **If the problem wasn't triggered by a specific action**, describe what you were doing before the problem happened and share more information using the guidelines below.
+
+Provide more context:
+
+* **Can you reproduce the problem with a minimum of options enabled?**
+* **Did the problem start happening recently** (e.g. after updating to a new version of Marlin) or was this always a problem?
+* If the problem started happening recently, **can you reproduce the problem in an older version of Marlin?** What's the most recent version in which the problem doesn't happen? You can download older versions of Marlin from [the releases page](https://github.com/MarlinFirmware/Marlin/releases).
+* **Can you reliably reproduce the issue?** If not, provide details about how often the problem happens and under which conditions it normally happens.
+
+Include details about your configuration and environment:
+
+* **Which version of Marlin are you using?** Marlin's exact version and build date can be seen in the startup message when a host connects to Marlin, or in the LCD Info menu (if enabled).
+* **What kind of 3D Printer and electronics are you using**?
+* **What kind of add-ons (probe, filament sensor) do you have**?
+* **Include your Configuration files.** Make a ZIP file containing `Configuration.h` and `Configuration_adv.h` and drop it on your reply.
+
+### Suggesting Features or Changes
+
+This section guides you through submitting a suggestion for Marlin, including completely new features and minor improvements to existing functionality. Following these guidelines helps maintainers and the community understand your suggestion and find related suggestions.
+
+Before creating a suggestion, please check [this list](#before-submitting-a-suggestion) as you might find out that you don't need to create one. When you are creating an enhancement suggestion, please [include as many details as possible](#how-do-i-submit-a-good-enhancement-suggestion). Fill in [the template](issue_template.md), including the steps that you imagine you would take if the feature you're requesting existed.
+
+#### Before Submitting a Feature Request
+
+* **Check the [Marlin website](http://marlinfw.org/)** for tips — you might discover that the feature is already included. Most importantly, check if you're using [the latest version of Marlin](https://github.com/MarlinFirmware/Marlin/releases) and if you can get the desired behavior by changing [Marlin's config settings](http://marlinfw.org/docs/configuration/configuration.html).
+* **Perform a [cursory search](https://github.com/MarlinFirmware/Marlin/issues?q=is%3Aissue)** to see if the enhancement has already been suggested. If it has, add a comment to the existing issue instead of opening a new one.
+
+#### How Do I Submit A (Good) Feature Request?
+
+Feature Requests are tracked as [GitHub issues](https://guides.github.com/features/issues/). Please follow these guidelines in your request:
+
+* **Use a clear and descriptive title** for the issue to identify the suggestion.
+* **Provide a step-by-step description of the requested feature** in as much detail as possible.
+* **Provide specific examples to demonstrate the steps**.
+* **Describe the current behavior** and **explain which behavior you expected to see instead** and why.
+* **Include screenshots and links to videos** which demonstrate the feature or point out the part of Marlin to which the request is related.
+* **Explain why this feature would be useful** to most Marlin users.
+* **Name other firmwares that have this feature, if any.**
+
+### Your First Code Contribution
+
+Unsure where to begin contributing to Marlin? You can start by looking through these `good-first-issue` and `help-wanted` issues:
+
+* [Beginner issues][good-first-issue] - issues which should only require a few lines of code, and a test or two.
+* [Help Wanted issues][help-wanted] - issues which should be a bit more involved than `beginner` issues.
+
+### Pull Requests
+
+Pull Requests should always be targeted to working branches (e.g., `bugfix-1.1.x` and/or `bugfix-2.0.x`) and never to release branches (e.g., `1.1.x`). If this is your first Pull Request, please read our [Guide to Pull Requests](http://marlinfw.org/docs/development/getting_started_pull_requests.html) and Github's [Pull Request](https://help.github.com/articles/creating-a-pull-request/) documentation.
+
+* Fill in [the required template](pull_request_template.md).
+* Don't include issue numbers in the PR title.
+* Include pictures, diagrams, and links to videos in your Pull Request to demonstrate your changes, if needed.
+* Follow the [Coding Standards](http://marlinfw.org/docs/development/coding_standards.html) posted on our website.
+* Document new code with clear and concise comments.
+* End all files with a newline.
+
+## Styleguides
+
+### Git Commit Messages
+
+* Use the present tense ("Add feature" not "Added feature").
+* Use the imperative mood ("Move cursor to..." not "Moves cursor to...").
+* Limit the first line to 72 characters or fewer.
+* Reference issues and Pull Requests liberally after the first line.
+
+### C++ Coding Standards
+
+* Please read and follow the [Coding Standards](http://marlinfw.org/docs/development/coding_standards.html) posted on our website. Failure to follow these guidelines will delay evaluation and acceptance of Pull Requests.
+
+### Documentation
+
+* Guidelines for documentation are still under development. In-general, be clear, concise, and to-the-point.

+   *   G26 Mesh Validation Tool
+   *
+   *   G26 is a Mesh Validation Tool intended to provide support for the Marlin Unified Bed Leveling System.
+   *   In order to fully utilize and benefit from the Marlin Unified Bed Leveling System an accurate Mesh must
+   *   be defined. G29 is designed to allow the user to quickly validate the correctness of her Mesh. It will
+   *   first heat the bed and nozzle. It will then print lines and circles along the Mesh Cell boundaries and
+   *   the intersections of those lines (respectively).
+   *
+   *   This action allows the user to immediately see where the Mesh is properly defined and where it needs to
+   *   be edited. The command will generate the Mesh lines closest to the nozzle's starting position. Alternatively
+   *   the user can specify the X and Y position of interest with command parameters. This allows the user to
+   *   focus on a particular area of the Mesh where attention is needed.
+   *
+   *   B #  Bed         Set the Bed Temperature. If not specified, a default of 60 C. will be assumed.
+   *
+   *   C    Current     When searching for Mesh Intersection points to draw, use the current nozzle location
+   *                    as the base for any distance comparison.
+   *
+   *   D    Disable     Disable the Unified Bed Leveling System. In the normal case the user is invoking this
+   *                    command to see how well a Mesh as been adjusted to match a print surface. In order to do
+   *                    this the Unified Bed Leveling System is turned on by the G26 command. The D parameter
+   *                    alters the command's normal behaviour and disables the Unified Bed Leveling System even if
+   *                    it is on.
+   *
+   *   H #  Hotend      Set the Nozzle Temperature. If not specified, a default of 205 C. will be assumed.
+   *
+   *   F #  Filament    Used to specify the diameter of the filament being used. If not specified
+   *                    1.75mm filament is assumed. If you are not getting acceptable results by using the
+   *                    'correct' numbers, you can scale this number up or down a little bit to change the amount
+   *                    of filament that is being extruded during the printing of the various lines on the bed.
+   *
+   *   K    Keep-On     Keep the heaters turned on at the end of the command.
+   *
+   *   L #  Layer       Layer height. (Height of nozzle above bed)  If not specified .20mm will be used.
+   *
+   *   O #  Ooooze      How much your nozzle will Ooooze filament while getting in position to print. This
+   *                    is over kill, but using this parameter will let you get the very first 'circle' perfect
+   *                    so you have a trophy to peel off of the bed and hang up to show how perfectly you have your
+   *                    Mesh calibrated. If not specified, a filament length of .3mm is assumed.
+   *
+   *   P #  Prime       Prime the nozzle with specified length of filament. If this parameter is not
+   *                    given, no prime action will take place. If the parameter specifies an amount, that much
+   *                    will be purged before continuing. If no amount is specified the command will start
+   *                    purging filament until the user provides an LCD Click and then it will continue with
+   *                    printing the Mesh. You can carefully remove the spent filament with a needle nose
+   *                    pliers while holding the LCD Click wheel in a depressed state. If you do not have
+   *                    an LCD, you must specify a value if you use P.
+   *
+   *   Q #  Multiplier  Retraction Multiplier. Normally not needed. Retraction defaults to 1.0mm and
+   *                    un-retraction is at 1.2mm   These numbers will be scaled by the specified amount
+   *
+   *   R #  Repeat      Prints the number of patterns given as a parameter, starting at the current location.
+   *                    If a parameter isn't given, every point will be printed unless G26 is interrupted.
+   *                    This works the same way that the UBL G29 P4 R parameter works.
+   *
+   *                    NOTE:  If you do not have an LCD, you -must- specify R. This is to ensure that you are
+   *                    aware that there's some risk associated with printing without the ability to abort in
+   *                    cases where mesh point Z value may be inaccurate. As above, if you do not include a
+   *                    parameter, every point will be printed.
+   *
+   *   S #  Nozzle      Used to control the size of nozzle diameter. If not specified, a .4mm nozzle is assumed.
+   *
+   *   U #  Random      Randomize the order that the circles are drawn on the bed. The search for the closest
+   *                    undrawn cicle is still done. But the distance to the location for each circle has a
+   *                    random number of the size specified added to it. Specifying S50 will give an interesting
+   *                    deviation from the normal behaviour on a 10 x 10 Mesh.
+   *
+   *   X #  X Coord.    Specify the starting location of the drawing activity.

+ *   #define MAX7219_CLK_PIN   77

+ * areas of the code, please be aware that the orientation (rotation) of the display can

+ * Endstop Interrupts

+ * the temperature-ISR via endstops.update(), most of the time finding no change.
+ * With this feature endstops.update() is called only when we know that at
+ * least one endstop has changed state, saving valuable CPU cycles.
+ *
+ * This feature only works when all used endstop pins can generate either an
+ * 'external interrupt' or a 'pin change interrupt'.
+ *
+ * Test whether pins issue interrupts on your board by flashing 'pin_interrupt_test.ino'.

+This is an example configuration for the CL-260 Ultimaker 2 clone.
+Change Z_MAX_POS to 300 for the CL-260MAX.
+
+(The printer is available on AliExpress; be aware that this is not a beginner's
+printer -- it needs tweaking and some parts replaced before being decent.)
+
+The printer comes with a quite old Marlin, the sources are available here:
+http://www.thingiverse.com/thing:1635830/ and I recommend replacing them.
+
+The setting "works" for my printer and the extruder using my calibration value.
+You might want to tweak some settings, e.g enable EEPROM, increase default Z speed, adjust homing speeds,...
+
+Have fun!

+# Example Configuration for BQ [Hephestos 2](http://www.bq.com/uk/hephestos-2)
+Based on the original configuration file shipped with the heavily modified Marlin fork by BQ.
+The forked firmware and configuration files can be found at the [BQ Github repository](https://github.com/bq/Marlin).
+
+NOTE: The look and feel of the LCD menu will change dramatically when using the original Marlin firmware.
+
+## Changelog
+ * 2018/05/30 - Configuration updated to the latest Marlin version (43a55a9af).
+                ABL Bilinear 5x5 is active by default.
+
+ * 2017/07/06 - Configuration updated to the latest Marlin version and added support for the
+                official BQ heated bed upgrade kit.
+
+ * 2016/12/13 - Configuration updated to the latest Marlin version.
+
+ * 2016/07/13 - Configuration updated to the latest Marlin version.
+
+ * 2016/06/21 - Disabled heated bed related options, activated software endstops and SD printing now
+               disables the heater when finishes printing.
+
+ * 2016/03/21 - Activated 4-point auto leveling by default and updated miscellaneous z-probe values.
+
+ * 2016/03/01 - The first release of Marlin's configuration file for the
+                BQ Hephestos 2 3D printer.
+
+
+## Support
+This configuration should work easily with the stock Hephestos 2, nevertheless if you encounter any
+issues you may contact me on [Github](https://github.com/jbrazio), [Twitter](https://twitter.com/jbrazio) or by mail.
