Z Offset Setting
The Z Offset Setting is used to adjust the distance between the Nozzle and the Print Bed.
This can be done before printing or during printing. If the distance between the Nozzle and
the Print Bed is too small, increase the Z Offset. if the distance between the Nozzle and the
Print Bed is too large, decrease the Z Offset. The proper distance between the Print Bed
and the Nozzle is when there is a slight amount of resistance when moving a piece of
ordinary printer paper between the Nozzle and the Print Bed.
If you changed the Z Offset prior to printing, turn the printer off and then back on to save
the setting as the default.
