Hello.
I have installed the second nozzle and i have made some prints with only that nozzle and it was time to test some dual color print.
The print turned out nice except for the color “mix” is it possible to make some adjustments so that the color for the letters does not mix with the color for the rest of the print? both material is PLA standard Velleman
The current settings right now is standard except for this
Temperatur 190 (PLA)
Flow 75
Retraction 3mm
speed 150mm/s
It’s very hard to avoid this even with the oozing shield. The retraction releases the pressure inside the nozzle but can’t prevent oozing due to gravity .
I suspect this is a result of using two quite different filaments. The black and white Velleman PLAs behave quite differently - I actually have different filament profiles for them. Black is quite ‘runny’, so I’m not surprised to see it smearing like that.
I printed the bracelet with blue and yellow which can use the same profile, and did not get any colour mixing.
Thanks for the replies.
Maybe i should make a new test with some other filaments.
Right now i have white, black, orange and purple in Velleman filament.
by the way, do you mind sharing your settings for the black filament? what have you made different with that, I have the same settings for all my PLA.

I am interested too
My Velleman Black PLA is currently printed at 70% flow, 188C, but I think it can probably go down to 185.
Yes this problem is indeed due to the contrasting colors and different oozing characteristics of different colors of filament.
It’s a hard problem to solve completely to be honest.
[quote=“Isaksson”]…the black filament? what have you made different with that, I have the same settings for all my PLA.[/quote]Sorry, missed answering the second part of your question. I use black PLA for all sorts of things. It can have quite a nice finish. Here are two boxes, for example, the second is printed at 0.2mm as a prototype (though it’s perfectly functional):
I understand from above message thread, that color, flow & other related settings could result in a different configuration profile per color (even within the same filament brand, as I guess we’re mostly using Velleman’s own).
Question to those experienced enough to make the call: would those values per color be something we could put on the wiki, maybe?
Or that Velleman technicians tests this on our behalf & reports their recommendations via the Vertex web pages on the company’s site?
I think, we’d all do well with a detail like this. (It would be an heroic task, of course - but the appreciation you’d get in return from your fellow users and / or customers would be endless).
Personal preferences will of course still float around, but - for example - I am still quite new to all this & have a single profile for all PLA… (I am using 190°C overall now, with modified retraction settings as advised on the forum earlier - but, as said, those settings are used for all the printjobs & all circumstances).
Would above be doable? A profile recommendation table of sorts, per color?
Cheers,

Good morning,
there is a thread for this around in the forum.
