And now with a flush object… nothing has changed in the amount flushed, and the object is mostly red, brown and black.. with white only on the last layers.
If we inspect layer by layer (layer 15 in this example), It starts printing with brown on the flush object. prints with brown my main objects… switches to white and directly print white on the main object… no white flush on my flush object.
But orca does the opposite (same layer, layer 15).. it start with brown on the main object… switches to white, and correctly flushes the white on the flush object.
Same issue here, regardless of using right click > Flush options> Fill into objects infill or from Flush into objects infill options under the multifilament menu, though its worth noting that selecting it by right clicking or the multifilament menu does not toggle the other also,
I’m using version V6.3.0.3420 and I can confirm this is still an issue… Frustrating as the amount of filament that is being wasted as a result of this setting not working correctly is vast over the number of multi-coloured prints I perform.
Same issue V6.3.0.3420. It’s frustrating. I wasted weeks trying to reduce waste by changing parameters and thinking I was doing something wrong. And the worst part is that @Creality doesn’t provide an answer or a solution.
I can confirm these same issues are happening on my K2 Plus with Creality Print v6.3.1.3548. No matter what I set the Flushing Volume Multiplier or other values to the results are exactly the same with heavy bleeding of black or red into other colors in the print that follow these colors.
Same issue for me, this is making my K2 unusable for color printing. This does not happen on my Bambu PS1 with AMS. Do we just scrap using Creality print and use a generic orca like from Elegoo?
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.
Hi sorry this is a bit late. How did you get the flushing estimate in the preview? Whenever I use a creality printer in orca it does not display the flushing volumes. I tried adding custom g code but that seemed to break the flush into object.
