The general recommendation is not to change +it from its default value 5.0, and this is the value used by default by the +`calibrate_shaper.py` script. If you did change it though, you should inform +the script about it by passing `--square_corner_velocity=...` parameter, e.g. +``` +~/klipper/scripts/calibrate_shaper.py /tmp/resonances_x_*.csv -o /tmp/shaper_calibrate_x.png --square_corner_velocity=10.0 +``` +so that it can calculate the maximum acceleration recommendations correctly. +Note that the `SHAPER_CALIBRATE` command already takes the configured +`square_corner_velocity` parameter into account, and there is no need +to specify it explicitly. + If you are doing a shaper re-calibration and the reported smoothing for the suggested shaper configuration is almost the same as what you got during the previous calibration, this step can be skipped. |
