Yesterday I wrote to Elegoo support service and become quickly this anwer
but I never try yet.

Thanks for your contact and purchasing Elegoo products.
1. Please level the build plate before you print a model. Please loose two fixed screws on build plate first when you level the build plate.
2. About the problem of the z-axis, you could loose the screws pointed by the arrow.
Then add a 1-2MM gasket on it and re-lock the screws. Thus the metal plate will move down 1-2MM which it can be detected by the sensor earlier and will not keep moving down too.
Please note that after adding the gasket, you need to re-level the build plate.
Hope all above can help you solve the problem.
Looking forward to your reply.
Best regards.
