Checking the R2 pogo pin functionality
If you notice that your bed seems to be heating up too slowly or your print bed is not being recognized check that your pogo pins are functioning properly.
Start by removing the heated bed.
Then check the six golden colored pins. Press down on each one, they should all be rebound when pressed down and have a spring-like feel.
If any of the pins are not rebounding back to their original position, you may need to contact customer support to obtain a replacement circuit board. See the example below of a pin that does not rebound fully.
