Flushing volume table - apply between separate prints?

Bambu Lab Software Bambu Studio
1

Have a P1S, AMS2 and using 1.7 and 2.0.1.50.

I’m aware of this table in Bambu studio (below), but what I cannot figure out is whether it is functional only when changing media during a single print run, or if the printer remembers the last print filament used between runs.

Going from black to white I get an ugly grey for quite some time, despite the setting here. I can chase it and make it bigger and bigger, but would like first to know if this even applies to different print runs, and remembered somewhere inside the printer?

In my experience, values entered here usually, but not always (!), temains.
Points of caution:

  • Using Makerworld print profiles as these may contain different modifications.
  • Always check after a Studio update (!) The multiplier occassionally set’s itself to zero.

Just in case, as it is a frequently overlooked feature: Individual entries can just be manually overwritten. That can be helpful in particular when doing multi-material prints as purge volumes are calculated based on color and brand.

I may be misreading your answer or you my question.

Not asking if changes in this table persist between prints (etc.).

I’m asking when this table takes effect to control flushing volumes. I assume within a print if I change filament, it takes affect at that point.

But let’s say today I print black, then tomorrow I print a whole separate model in white. Does it remember it is changing from black to white and use this table, or does it just do some standardized flush when loading the filament?

YMMV, In my A1 it does not remember the filament used in the last print, so it is a standard purge for the start of the next print.

My assumption from the above images those volumes would come from using all those colours for the same print especially when you compare white with the other darker colours

My recent white and black prints flush a grey into the purge tower , but have printed as expected

I’m thinking that is my problem here. Any suggestions on how to manually do a larger purge when I know it will be a problem?

You could do a manual load of the new color before starting the print and then the print startup flushing may be enough or, if you know G-Code, I do not, you could add lines to the startup G-Code section to increase the flushing before the print.

I’m not sure a manual load is any different than just selecting the color, but maybe a manual load, an unload, and then let the print do the next load again. Maybe that will double up. I’ll experiment. Thanks.

You are right, I misunderstood.

Other than manually purging, you could add additional purging to the starting Gcode and save it as a custom printer profile. However, I expect manual purging to be more pragmatic.
