Number of input shaper "test-moves"?
-
Hi,
today i used input shaping for the first time on a very fragile machine (modix big meter), so far everything worked well thanks to the excellent documentation and i ended up with a good ZVDD compensation at 22hz.
I still have to do some before and after testing however i was a bit suprised by how quick the testing moves were done.
I followed the input shaper plugin and it suggested one x and one y move, which surprised me a bit.
from what i can see from klipper input shaping its a much longer procedure with all kinds of testmoves in all directions, with different speeds and differently long moves.I wonder if I should add more moves or if I missed a step somewhere, or is there a library of testmoves out there somewhere?
Can someone shed some light on how the input shaper procedure is supposed to be done?
Cheers

@sungod3k nope, that's correct. RRF does one move in X and Y at the maximum speeds etc set in config.g.
22Hz seems a little low however -
it s huge 1x1x1 meter machine, so it might not respomd on the normal frequencies

@sungod3k can you post your graphs? would be curious to see.
IIRC, anything below 20Hz in klipper is discarded
