I was trying to print a file where the printer has to stop for a change of filament 4 times (M600). It didn’t. When I checked the gcode I did find 4 instances of M600.
What could be the reason?

Can you paste in part of the code so we can quickly see if it is that?
Are you trying to manually change filament? Bambu doesn’t use the Marlin style M600 gcode.

I’m having the same problem today on the A1. I just paused at the appropriate layers instead and did it manually in the end. Is there another command for Bambu printers then? I’ve been using Orca slicer.

Yes, manually.
In this video https://www.youtube.com/watch?v=ua3DoRlmN-c
around minute 7:30 one can see that he enters M600 in what seems to be Bambu Studio. If it should be Orca, I am surprised that Orca would accept but not BL Studio.
While Teaching Tech does enter M600 in the video, the difference is that he is slicing for a non Bambu printer. As I said before Bambu printers don’t recognize M600.
To correctly manually change filament on a Bambu (with correct purges and wipes) you need to add gcode such as listed here.

The pause code for Bambu printers is not M600. It is: M400 U1.

Studio will add a pause (M400 U1) with just a right click on the appropriate layer.
There had been a problem with layer shifts after a pause, but I believe that was corrected months ago. If not, using this code prevented the problem:
M400 U1 ;pause
G28 X ;home
That’s all I’ve needed to change filament colors without an AMS.
I’ll try that first thing in the morning (different time zone).
Thanks again to all.
