Probably a stupid question, but will we ever have something like a microwave to make things cold? Is there a reason this can't exist? (lemmy.dbzer0.com)

No, what it should do is:

when timer ends or stop button is pressed it should turn off microwaves but keep spinning until original position
when door is opened just stop everything immediately

This way you can stop the plate manually at any position but when operating microwave in the usual way you get the benefit of the cup always pointing the right way.

Better yet, change the rotation speed to match the timer.

It would require variable speed motors and more complex chip and programming so it would be more expensive. Just spinning the plate at the same speed until it makes a full turn could be solved mechanically.

I mean, sure, but there are microwaves out there that measure the heat of food put in it to cook it automatically. I figure a variable speed to match an input time would be just a bit easier to accomplish than that.

Have it calculate the amount of full rotations and round it down to the nearest whole number. Worst case scenario, your cup is static for 5–10 seconds before the microwave stops.

That can be done, just takes a more expensive Platten motor, and some more code in the control unit.
