Description
EBB SB2209 CAN V1.0 (RP2040) + Voron Tap, suddenly unable to get Klipper to trigger the z endstop. Tried shorting gpio21 directly to gnd and no change within Klipper. Also tried connecting to gpio22 and gpio6 but nothing will get Klipper to trigger the z endstop. Tried a fresh install of Klipper from scratch, using up-to-date install, no change.
Checked with Voron discord, I am not the only user of SB2209(RP2040) that is having issues with Voron Tap.

Research direction
The report names EBB SB2209 CAN V1.0, RP2040, Voron Tap, Klipper, and GPIO21, GPIO22, and GPIO6, but gives no repository files or tests to start from. Reproduce the endstop failure with the stated wiring and compare Klipper's GPIO behavior; done means the Z endstop triggers reliably.
