UPDATE as of 16/02/26. — WORKING on my K2 (standard) combo after the latest update. Info and write up is under the “MAKE” section below. Please scroll down there to see all about it now working on the K2 series printers as well now. Thanks

1 - Pic your printer/slicer file from my files here, Then open Creality Print (or ***********) and open the 3MF into a new project

You will then get the loaded project that should look something like this

2 - if you have opened the file for your printer (K1 Max,Creality Hi, etc) there will only be a couple of settings that you need to change.

Pic your colours and filament you want to use then click on Flushing options.

You want this to look like this.

If it looks like this(which it will if you have changed the colours)

You need to change the flushing values all back to 50 as per my first picture and leave the multiplier at 1.00

3 - The only other thing to check before slicing is that your Sparse & Solid infill Directions still look like this

If they are not 0 then change them to 0 to look like my above picture.

4 - Slicing time, Pic which plate you want to print (2,3,or 4 Colours), Click on that plate so it is chosen and then click the SLICE button. Load up your filament if you haven’t already done it and then once your all ready click the Print button (or send the file to the the printer and start your print)

5 - once its finished printing it should look like this.

6 - Reading the results. I use a Razor blade scraper or the likes to carefully remove the samples and then place them on a white back ground (piece of paper or the likes) then you can look at each sample and choose when the colour changes to the next colour and read there values. So if you look at the below picture.

From the Left (Pink going into yellow) the reading would be around 160, so you then add 50(our flushing value we set) and your flushing value for pink into yellow would be 210. Add that to your flushing table on the slicer and go to the next example yellow to pink, which is 175 + 50 = 225 is what you put into your flushing value for yellow going into pink. You then just work along the rest of your examples just like we have done & ive shown in the picture

Now you should have cut your waste in half and saving yourself lots of filament.

Here’s a before and after example & I can cut it down even further as I was being very conservative on my numbers.

Things to note - when doing say Black to White or light colours you may need more than the 500 scale to bleed out the colour, if you strike this just make the flushing amount for Example Black into white 200 and then when you choose the amount on your printed example you would do That + 200 = what you get. You may not run into this but just wanted to note it here.

I keep my tests and then I can look back when im about to do my print and if ive tested those colours I can just read the example and put it into the flushing volume in the slicer.

But it’s a quickish test of only about 25mins for 4 colours and with the savings it will be well worth doing.

This will work on Creality Print (CP) & Orca Slicer (Orca) but pics may look different in orca slicer then on here..

Feel free to ask if you have any questions.
