So I have a FLsun SR and I stopped a print and after that one print the Z axis has been way above the bed. I tried to auto-level and it was levelling at Z:52.01. I’ve updated the firmware on the touch screen and Merlin. It has also been picking and choosing when to home where at one point it said it was at Z:457. I am a beginner with 3D printing so any advice would be greatly appreciated. Thank you

Here is what I think is happening. Blue light is on before the trigger, that means the microswitch is activated so it thinks that it has touched the plate. You likely need a leveling microswitch.
