Z distance blockers (for e.g. Anet A8)

In order to set both Z motors to (about) the same height before leveling:
1) Home X
2) turn off steppers
3) Place distancers on Z rods
4) manually move z axis down
5) Move Z axis up using the position menu
6) Home all

For even better adjustment, you should make a mark on the Z rod connectors and on the base of the Z rods, sometimes they are off by just one step.

**After a long time of having marks on the Z rod connectors, I'd recommend to try that first.** I rarely use these blockers
