The adapter does have to be removed and reinserted in order to get things to refresh, so flexible ones designed to make it a full size SD etc. aren’t all that useful as you still have to remove the micro SD end.
So I use the microSD card as right now it is
a) a nice fast way to get timelapses and videos from the printer
b) an easy way to have a set of models or files printed frequently on hand at any time
c) the only way to print when you’re using an alternative slicer (which I do on occasion as Bambu Studio currently is missing some features and handles things in a different way to others)
It does help that I have a Micro SD slot in my laptop, so it’s a matter of seconds moving the card from one to the other.
I keep installed for the same reasons as @mowcius. I do use one of the ejectors to make it quick to remove. I also keep it on had for reviewing full video of failed prints to help isolate a reason.
How do you format the card on the printer? I don’t see an option for that, and it doesn’t prompt me to when I put the card in. I’m sure I’m missing something obvious, but I don’t see it.
