After a year printer y homing failure

[sjason1377]

Y axis started to ignore endstop. Switch works fine tested no noise led reports correctly and m122 call show correct switch position. I removed some gcode files to free up card space and the issue started then. ; Configuration file for Duet Ethernet (firmware version 1.17 to 1.19)
