I made a rack so I can stack all my large AMS on top of each other so needed more cables to daisy chain all 4 AMS to the P1S.
Viisually, the male cable ends look identical.
Bambu Lab saying:
may cause
Is quite vague especially when it is likely that many owners have a mix of old and new AMS devices connected.
Assumptions are risky but the cables have not caused enough of an issue to prompt Bambu Lab to recall old cables. They can look at the sell dates and easily determine who has old cables and who has new.
