SAVE_INPUT_SHAPER is not a valid command, SET_INPUT_SHAPER is.

See https://www.klipper3d.org/G-Codes.html?h=set_input_shaper#set_input_shaper

Maybe this is k1 specific but SAVE_INPUT_SHAPER is not a klipper command in at least v0.11. I have not change the one in the k1 scripts file.

Hmm I'm not aware of the set variant.

Guppy uses some of its own klippy extras to do some of these things:

Could be a extra command, haven't found it anywhere but the set_input_shaper is the default klipper one.

Uses set_input_shaper so that is correct. But for the gcode command send over the network (not via python script) is not doing anything. I've tried googeling the SAVE_INPUT_SHAPER but it gives zero results.
