Failed homing and bed level at temp above 70c

Bambu Lab X1 Series Bambu Lab X1C

An external disturbance was detected on force sensor 1

Added a new X1C to my modest print farm today, first print, I get this error, but only when the bed is at temp. I print polycarbonate, so the bed is a toasty 110c. When I perform a self test, everything passes, when I attempt a print I get the error, if I run a self test while the bed is still hot, it fails. If I let it cool down, it passes again. Should I assume bed sensor 1 is bad and return the printer?

Try backing off the bed adjuster nut a small amount for force sensor 1 to give it a little bigger sensor air gap when hot.
