Keys sticking when moving all axis

While trying to move the coordinance either x, y or z the key seems to stick sometimes especially for z. While homing today my bit went into the material and I had to stop it by shutting down.
So I have 2 issues.

  1. I can’t get it to home properly now. After the x and y homes the Z continues to go way down with stopping to home and I have to shut down right away.

  2. How can I prevent the movement from sticking in the future?

Any assistance would be appreciated.
