Printers are precision motion systems pretending to be appliances. Ship one like a toaster and it arrives as a calibration project, or scrap.
The short version of doing it right: re-fit the factory foam if you kept it (keep it). Lock every axis: gantry strapped, bed screwed down or blocked, print head immobilized. Remove anything glass. Remove spools, drybox them separately. Photograph everything before the lid closes, and insure it for replacement value, not purchase price.
We've moved machines between provinces, in and out of an RV, and to field jobs. If you're relocating a machine or a whole farm, the checklist above is the difference between printing the day it arrives and waiting a month for parts.
