Like Hu says, I sure read a lot of messages about people losing steps on their Z-axis, and always thinking it's some other problem, when it's really underpowered. Instead of 50%, I'd double what you think you need. The force required to push down isn't the problem, it's abruptly pulling it up while it's moving down.
