This is a fork of Klipper (GitHub), a 3d-Printer firmware. The code in this repo adds experimental features to reduce resonances and ringing during printing. The current focus is to extensively test adaptive S-Curve acceleration - the input shaping feature was already integrated into the mainline Klipper codebase.

The current branch recommended for the broad use is scurve-shaping (installation and tuning instructions). All other branches are either deprecated in favor of this one, or have been published for convenience and contain more experimental features and lack proper documentation. Please update your installation to the suggested branch if you are using one of the older branches.

The feedback is welcome at the Adaptive acceleration support feature request in the main Klipper repo. If you have issues specifically with input shaping, please use this ticket instead. In general, if you report bugs, please double-check that the issue cannot be reproduced on the mainline Klipper code without input shaping, and attach the full klippy.log of the failed print attempt to your bug report. Typically the problematic GCode is also required to debug the issue. However, if the issue can be reproduced on the mainline Klipper code, please create a separate issue here instead, and attach klippy.log from the attempt on the mainline code.

Updates:

• 2020-08-04: [input_shaper] is fully merged into the mainline Klipper (together with tuning docs).
• 2020-07-09: [input_shaper] is merged into the mainline Klipper (except the docs for now)! Other approaches (e.g. [smooth_axis]) are incompatible with input shaping, which means that all S-Curve branches except scurve-shaping can no longer be updated. All users of scurve-smoothing and scurve-c-combine-smoothpa are encouraged to migrate to scurve-shaping branch (or to the mainline Klipper) and update their configurations accordingly.
• 2020-07-06: scurve-shaping branch is now recommended for broad use.
