I am having a problem with my 1.1.9 firmware.

When I have AUTO_BED_LEVELING_BILINEAR enabled the printer homes Z in the wrong direction - the nozzle goes up instead of down when I issue G28.

With AUTO_BED_LEVELING_BILINEAR disabled the printer homes as expected, but that means I can't auto align the bed. Setting Z_HOME_DIR to 1 does get it moving in the right direction, but I'm then stuffed for printing because the Z axis goes in the wrong direction.

Works fine using a BLTouch probe, but I'm trying to use an IR or capacitive probe.

did u solve this?
Would be nice to post the solution if you did.
