I do a lot of R&D prints of mostly small parts. The current part takes 2 minutes to print, yet the whole operation takes 10 minutes. Why can’t the printer re-use the settings from the previous print? If Bambu Studio had an option box saying Re-use settings it would make things go much faster.

I turn off auto-leveling after the first print of the day, and turn off flow calibration because I manually calibrate all my filaments. This saves a few minutes, but each print will always need to some time to heat and position the nozzle and bed, and get the plastic flowing.
Turn off the check-first-layer thing, too.
If you don’t run bed leveling and flow calibration and first-layer-check, and if you’re using an AMS you leave the filament loaded, the printer’s start up time is comparable to any other printer.

Ikraus & RocketSled - thanks
Yep, got everything turned off after the first print which I usually do with just bed levelling. It still seems to spend a lot of time moving the head to and fro for no obvious reason. With my Creality CR10-S Pro after the bed and nozzle are up to temp and it has homed the head it starts printing more or less instantly.
In the grand scheme of things it’s not a major issue since the quality is absolutely superb. I just wondered if there was a GCode or something that could say ‘use the previous settings’.
I’d have to look at the gcode, but I believe it is calibrating the Z offset before each print. Like @Ikraus, I also calibrate each filament, so no flow calibration needed, and also do bed leveling once a day or if I switch build plates.
However, the Z offset is so crucial to getting the first layer perfect, that I would probably not turn that off even if it was an option. Just removing (and flexing), then replacing the build plate can affect the results. I also leave the first layer detection enabled on my X1C because it takes very little time overall. Plus, I want to get some value out of the lidar I paid for 
Also, I watched the camera while the printer was getting started on a job, and I noticed the lidar was active while scanning the plate. I assume this is the object detection scan, as it only seemed to scan the build area of the print job. Seems reasonable to be able to turn this off manually if you know the plate is clear, but also did not take that much time in the big scheme of things.
There is a check for the correct plate , which can be turned off , but i wouldn’t a few times saved me
- I turn off first layer inspection
- turned off the autoflow as i do not use it using manual
- The plate check is ON as a few times forgot to change or just selected the wrong one
- Bed Leveling and Z ON
- Vibration compensation OFF/ON lately more ON as moved the printer a few times and no need for custom code
Here is a good examples, but just use what you need

Also if you open the Machine Gcode is well documented and you can play with it not very difficult , mainly comment out sections .
