ncrease max_accel and max_accel_to_decel parameters in your printer.cfg to 7000. Note that this is only needed for tuning, and more proper value will be selected in the corresponding section.
If square_corner_velocity parameter was changed, revert it back to 5.0. It is not advised to increase it when using the input shaper because it can cause more smoothing in parts - it is better to use higher acceleration value instead.
Restart the firmware: RESTART.
Disable Pressure Advance: SET_PRESSURE_ADVANCE ADVANCE=0.
If you have already added [input_shaper] section to the printer.cfg, execute SET_INPUT_SHAPER SHAPER_FREQ_X=0 SHAPER_FREQ_Y=0 command. If you get “Unknown command” error, you can safely ignore it at this point and continue with the measurements.
Execute the command TUNING_TOWER COMMAND=SET_VELOCITY_LIMIT PARAMETER=ACCEL START=1250 FACTOR=100 BAND=5.
а можешь показать, что под командой Tuning_tower он печатает?
