Hello, I recently updated marlin on my FLSun reprap kit, and I've changed the necessary parameters in the configuration.h file. Now, when I home z, or even send a g28 z0 command, the Z axis homes up instead of down. It's set to home to min, and when I move the z axis up or down, it moves in the correct direction. I don't have this issue with my X or Y homing, so I'm kind of lost as to why it would home in the wrong direction. Thanks!
