Setting zoffset in cura

There used to be a post showing the gcode to adjust zoffset, but I can’t find it anymore. I haven’t printed for a bit, but now my print head is floating above the PEI about 5 mm… tuning zoffset seems the thing but I can’t find nor remember the instructions to set zoffset in cura.

Any help appreciated.

Are you printing with the mini or the taz?

Is this post by Rhoderman the one you were thinking of? I bookmarked it, since I knew I’d forget how to do it.
