I recently bought a K2 pro combo and coming from a Geeetech A20M which I paired with a mosaic palette 2 for multicolor printing. That was moderately successful but I grew tired of the fiddley nature of that setup.
I was excited to get the CFS to manage multiple colors. I’m pleased with the hardware performance, however, paired with creality print it is a big disappointment. Even setting flushing volumes to 0 I’m getting an enormous amount of wasted filament. For example I printed a model with white 98% and blue 2% filament with the finished model coming in at 21.3 g and wasted filament 137.2 g (not even close to that estimated on teh preview). That’s a 7 to 1 ratio! Unless I missed some item in the documentation. I watched as the printer spit out 6-10 cm of white filament even when there was no bleeding with the blue.
I also printed the same model with filament changes at multiple layers with flushing set to 0 knowing full there should be bleeding and it produced clean layers.
On discord there is mention of hacking the firmware to reduce this wastage, but why isn’t working out of the box? I bought this so I can concentrate on designing and printing, not hacking.
In addition the filament library management is a complete joke. Why even enter custom filaments if you can’t load that onto the printer for direct access with auto mapping. We should also be to add custom names to the vendor list,to view as a choice in the pull down. I get having the Creality filaments as a priority but this is the real world.
This is not a new concern, as I’ve read with other models. Creality development team get your act together.
I agree. Too much waste.
Adjusting the flushing for multi-color prints.
Do not set to 0, this lets the machine decide.
I have had some success setting them all to 200. The lowest recommended for the tables are 183.
I had one of those where the flushing volume exceeded to end item volume. Setting all to 200 and slicing reduced it to correct values. Waste was less then are the item.
Pretty sure there is am issue that is not scaling correctly.
On the filament part. I am digging through the profiles to see how to build my own. I have found that if you stick with “Generic” when you make rfid tags works good enough for filament tracking. You just have to select your custom filament in the slicer. I too don’t understand why the printer cannot read the software filament when it loads new filament and allow adding to the filament database without sudo access. That should be in user space.
Hello,
I made a small test here (with my newly bought K2)
Test here for text (and scroll up for pictures)
Short: With Setting Multiplier to zero “0”, the least waste has been produced. I contacted also Crealtity support about this topic, that the printer ignores basically the flush settings of the slicer. Looking through the G-Code, I found only Toolchanges - so the flush must somehow performed by the printer, although the files sent to the printer have all the settings in it at the end.
Stuck here as well.
I have my flush set to 30 for all filament colors and I also have the flush to infill on. Then I set up a purge object that color isn’t a big deal like a silly clicker toy (i give them to kids that come in my business) and line up enough that my waste gets down to next to nothing, mostly.
I still get what i think is excessive waste on 4 color prints. I tried to set the prime volume lower but got an error and the software changed it back.
I’ve seen people have changed some other setting in a reddit thread but the info was for using another slicer. I’ll wait til someone figures it out using crealitys slicer. In the mean time, this works well for me and what I use my printers for.
