Print Startup Routine

I’m just curious about the routine the printer goes through evry time before starting a print job.

On my Creality Hi, the nozzle and the bed heat up, the gantry goes to the top and does some checks then comes down again, dances around the bed a bit and stops. Then the nozzle cools down to 175deg and does a bit more of a dance, then cools down to 120deg then a bit more dancing then the nozzel heat goes off altogether, the gantry goes up t othe top again, comes down then stops. During this time there has been a couple of wasteful and unnecessary purges. Then the nozzle heats up again and finally the print starts.

And it does this routine for EVERY print. Take forever. It shoild n’t take anymore than a minute to do a bed level check. Why all the filament purging and powering down th nozzle for no apparent reason?

Any suggestions will be appreciated.
