I recently got an A1, and overall I’ve been very happy with the results and the smarts built into the thing.
From what I see, a lot of the pre-print activity is baked into the machine start gcode packaged with bambuslicer and some macros embedded into the firmware.
I would like to have a profile that can disable the EXTREMELY loud and buzzing motor vibration test - I cannot start a new print on this printer in my home after 10pm in its current form 
I would like it to retain the last tuning configuration ideally, so there is gcode:
M982.2 S1 ; turn on cog noise reduction
M1002 gcode_claim_action : 13
- And much later on:
M975 S1 ; turn on mech mode supression
So, which of those 3 functions should I disable to “Skip the tuning, use the last saved value”? I’m guessing removing one or both of the first calls, and leaving the last one.
I see hints of similar profiles being shared for the X1C, with links to 404’ed resources hosted on third party websites like printables/thingiverse. It would be nice to have a similar A1 “ultra fast start YOLO” profile, but realistically I need to disable this one thing and exactly this one thing, I’m not opposed to the time taken by calibration, only to the resonant frequencies that it is very good at generating – those frequencies travel thru this old house’s frame like a freight train.
