Input shaping not working on markforged kinematics [BUG???]

SanderLPFRG

Hi all,
Based on my last topic, I suspect that there might be a bug in the 3.5.0-beta.2 firmware.

I cannot get Input shaping to work on my machine with markforged kinematics.

Things i have tried;

Low jerk, down to 100mm/min
High speed and accell, up to 170mm/s and 9000mm/s2
Every type of input shaper
Different frequencies

Is there anything I can do to see if this is a bug or something else?

@SanderLPFRG I think there were some Input Shaping changes between 3.5.0.beta.2 and 3.5.0.beta.4.

Might be worth a try.

@Herve_Smith Thanks for the reaction.

Fortunately, I did that and tried to update. However, since I got an error and it does not work I was hoping to see if I did something wrong.

The pi reports tere are no releases available... any ideas?

@Herve_Smith
i did, but it kept giving errors, I switched back and forth between stable and unstable, reset date/time, and it then worked.

IS is working in beta4 on markforged kinematics, so it indeed was a bug in beta2
