Is Input Shaper not working or what's causing ringing?

@Arminas you could do G0 H2 X... and G0 H2 Y.... moves, since H2 indicates a motor only move which will give you a diagonal motion on CoreXY.

Arminas

@oliof okay, and how to read the accelerometer data during that move?

oliof

@Arminas You run M956 Pnn A1 S200 before the move. https://docs.duet3d.com/User_manual/Reference/Gcodes#m956-collect-accelerometer-data-and-write-to-file

Arminas

@oliof it will be displayed via DWC input shaper plugin?

oliof

@Arminas the input shaper plugin reads the generated files, so: Yes, if you choose the right file (see the link I provided to figure out the file name, or how to set a unique one).

Arminas

@oliof Thank you. Maybe you know why I can not complete the measurement? I can perform a movement but nothing happens next

oliof

@Arminas first step would be to check whether the file was generated or not.

Arminas

@oliof already found the issue. It works well with DWC 3.5 version. (mine was 3.4.6).

Although, I think I have another problem, but as I understand it should be solved.. Looks like Input shaper is not applied for Y axis, which is connected to duex expansion board. Is it possible that IS only works with mainboard?

oliof

@Arminas I am not aware of any limitations with the Duex5, that's a question for @dc42

@Arminas theres no limitation regarding duex as its basically part of the mainboard
