Has anyone else had issues with flushing volumes not changing and total material weight going up when you add an object and set it to be flushed into? Not sure what im doing wrong if anything. It seems to work just fine on my Bambu. I’m about to redownload PRUSA and see if it’s any different there.
Still not working. Creality told me to:
do try the following;
Ensure you’re on the newest Creality Print (v6.3+ as of late 2025) and K2 Plus firmware bugs persist but updates sometimes help. Load models, paint colors, enable prime tower, right-click your flush object > Flush Options, tick all relevant color transitions and “flush into infill,” and set its layer volume higher than needed purge. Slice, then preview layers to confirm flushing hits the object before main prints (it often prints mains first, wasting filament).

Switch to Orca Slicer (import K2 Plus profile) it reliably redirects flush (e.g., 77g to 49g waste) unlike Creality Print.
Optimize color order (dark to light) and add 1-2 dedicated flush objects per transition.
If CFS-enabled, check printer’s “Calculation of Flush Amounts” in settings and disable any fixed firmware flush stages
Download Creality’s official K2 Plus Orca config .3mf from their wiki (drag into Orca to install), calibrate flow/pressure via Orca tools, and map filaments to CFS slots matching your print colors. If “send to printer” fails, slice/export to USB as fallback this way over Creality Print for purge reduction.

Which doesn’t work either
