Discord Chat

There is a Discord server dedicated to Klipper at: https://discord.klipper3d.org.

This server is run by a community of Klipper enthusiasts dedicated to discussions on Klipper. It allows users to chat with other users in real-time.

I have a question about Klipper

Many questions we receive are already answered in the Klipper documentation. Please be sure to to read the documentation and follow the directions provided there.

It is also possible to search for similar questions in the Klipper Community Forum.

If you are interested in sharing your knowledge and experience with other Klipper users then you can join the Klipper Community Forum or Klipper Discord Chat. Both are communities where Klipper users can discuss Klipper with other users.

Many questions we receive are general 3d-printing questions that are not specific to Klipper. If you have a general question or are experiencing general printing problems, then you will likely get a better response by asking in a general 3d-printing forum or a forum dedicated to your printer hardware.

Do not open a Klipper github issue to ask a question.

I have a feature request

All new features require someone interested and able to implement that feature. If you are interested in helping to implement or test a new feature, you can search for ongoing developments in the Klipper Community Forum. There is also Klipper Discord Chat for discussions between collaborators.

Do not open a Klipper github issue to request a feature.

Help! It doesn't work!

Unfortunately, we receive many more requests for help than we could possibly answer. Most problem reports we see are eventually tracked down to:

Subtle errors in the hardware, or
Not following all the steps described in the Klipper documentation.

If you are experiencing problems we recommend you carefully read the Klipper documentation and double check that all steps were followed.

If you are experiencing a printing problem, then we recommend carefully inspecting the printer hardware (all joints, wires, screws, etc.) and verify nothing is abnormal. We find most printing problems are not related to the Klipper software. If you do find a problem with the printer hardware then you will likely get a better response by searching in a general 3d-printing forum or in a forum dedicated to your printer hardware.

I have diagnosed a defect in the Klipper software

Klipper is an open-source project and we appreciate when collaborators diagnose errors in the software.

There is important information that will be needed in order to fix a bug. Please follow these steps:

Be sure the bug is in the Klipper software. If you are thinking "there is a problem, I can't figure out why, and therefore it is a Klipper bug", then do not open a github issue. In that case, someone interested and able will need to first research and diagnose the root cause of the problem. If you would like to share the results of your research or check if other users are experiencing similar issues then you can search the Klipper Community Forum.
Make sure you are running unmodified code from https://github.com/KevinOConnor/klipper. If the code has been modified or is obtained from another source, then you will need to reproduce the problem on the unmodified code from https://github.com/KevinOConnor/klipper prior to reporting an issue.
If possible, run an M112 command in the OctoPrint terminal window immediately after the undesirable event occurs. This causes Klipper to go into a "shutdown state" and it will cause additional debugging information to be written to the log file.
Obtain the Klipper log file from the event. The log file has been engineered to answer common questions the Klipper developers have about the software and its environment (software version, hardware type, configuration, event timing, and hundreds of other questions).
1. The Klipper log file is located in /tmp/klippy.log on the Klipper "host" computer (the Raspberry Pi).
2. An "scp" or "sftp" utility is needed to copy this log file to your desktop computer. The "scp" utility comes standard with Linux and MacOS desktops. There are freely available scp utilities for other desktops (eg, WinSCP). If using a graphical scp utility that can not directly copy /tmp/klippy.log then repeatedly click on .. or parent folder until you get to the root directory, click on the tmp folder, and then select the klippy.log file.
3. Copy the log file to your desktop so that it can be attached to an issue report.
4. Do not modify the log file in any way; do not provide a snippet of the log. Only the full unmodified log file provides the necessary information.
5. If the log file is very large (eg, greater than 2MB) then one may need to compress the log with zip or gzip.
Open a new github issue at https://github.com/KevinOConnor/klipper/issues and provide a clear description of the problem. The Klipper developers need to understand what steps were taken, what the desired outcome was, and what outcome actually occurred. The Klipper log file must be attached to that ticket:

I am making changes that I'd like to include in Klipper

Klipper is open-source software and we appreciate new contributions.

New contributions (for both code and documentation) are submitted via Github Pull Requests. See the CONTRIBUTING document for important information.

There are several documents for developers. If you have questions on the code then you can also ask in the Klipper Community Forum or on the Klipper Community Discord. If you would like to provide an update on your current progress then you can open a Github issue with the location of your code, an overview of the changes, and a description of its current status.
