two fysetc input shapers config

[xenoton79]

If someone wants to connect two at the same time, here is the config.

`# Obtain definition by "ls -l /dev/serial/by-id/" then unplug to verify
[mcu hotend]
serial: /dev/serial/by-id/***
[mcu bed]
serial: /dev/serial/by-id/***

Hi @xenoton79,

Can you provide an example on how to do this same thing for 3 Fysetc Input Shapers? I have a Sovol SV04, so I have X1, X2 and Y.

I'm at a lost because accel_chip_x and accel_chip_y are specific commands... I'm wondering how to do this for a dual carriage.

I'm not sure if I can help with this or if it even works that way.

According to my logic you only have one X axis. No matter how many extruders are attached to it.
So you only need two Fysetc input shapers.

However, I'm not sure what is referred to as X in your case and whether input shaping can even handle X1 and X2.

You have to test this yourself.
Otherwise, here is an interpretation of how it could work.

Thank you for the quick reply.

The SV04, the IDEX bed slinger, visually have 1 X-rail but have 2 independent belts and 2 independent motors on this rail and the 2 X heads move independently on X.

Unfortunately, I don't think accel_chip_x1 or aceel_chip_x2 are valid configuration parameters.
