My printer takes almost 10 minutes before any actual printing takes place. I understand that certain things are necessary for startup (heating the bed/nozzle, performing a purge, etc.) but my printer almost always heats the nozzle, then cools it down to 140c, and then heats it back up to the necessary temperature.

Below is the machine start code in my OrcaSlicer printer settings:

I own a FlashForge Adventurer 5M and have noticed that my prints take about 12 minutes from me pushing the button to start the print to actually begin printing. I hope someone can help me know what's going on and what I can do to fix it. FYI I use orcaslicer and this happens on every print I use regardless of nozzle, stl file, material, etc. This is what happened just now for example:

1. The printer spends about 7 to 8 minutes cooling down the hot end and doing nothing else (this was just after replacing the nozzle and running the filament through).

2. It then heated the hot end up to 220°c.

3. It booped the surface of the print bed (sorry, I don't know the technical term but I assume it had to do with calibrating the height)

4. Then cooled all the way down to 140°.

5. Booped the bed again.

6. Heated back up again to 220°

7. Wiped the excess filament onto the edge of the print bed.

8. Then it immediately began printing WHILE gradually heating up from 220 to 260! It was halfway through the first layer before it had reached the target temp.

I know very little about this stuff, but is all this normal? If it is, then can someone please tell me what the point of all those steps are.

If it's not normal, can someone please tell me what I need to do to fix it?

Specs for this specific print just now:
