Purging volumes not calculating properly #4166

Open HitLuca opened 7 months ago

What happened?

When slicing a multicolor print a Purging volumes... button is available, which contains the purged amount of filament for each color transition. Even with Advanced wipe tower purge volume calculus enabled and various settings changed for it, the purge matrix keeps using default values (140) for any filament change regardless of the pigment % of each color.

The pictures above have tool 1 with pigment % of 1, and tool 2 with pigment % of 0 as an example. Also if using the same filament twice as tool color the matrix purges the same amount even if should be close to 0

After some more testing I found out that the advanced volume calculus works as expected, but overrides the user-defined volumes in the matrix. I would assume that the values in the matrix are the final ones, and the smart calculus only defines the starting point. Disabling this feature allows me to properly change the purge volumes, and enabling it properly changes volumes between filaments based on their pigment %.

My suggestion would be to always start from the smart values if enabled, and if the setting is changed the user should be notified that the matrix values will be recalculated (or have the option to skip it)
