Hi, that’s not white color; it’s the filament seam. But if you want to be more sure, remove color 4 (white PLA) and see if the same thing appears—that’s what I mean by seams. If not, then it was indeed white filament.
Agreed, nothing to worry about. The white dots are markers for the start and end of trajectories for the nozzle, ie seams.
Thanks for both explanations. I would just have to use white PLA as the base for my first test of colour printing! I’m relieved it’s working properly.
I find that a slightly annoying feature of Orca. If you look on the “Line Type” drop-down (instead of "Filament as you have now, top right), you’ll see the white colour code listed as “Seams”, and for some reason that applies on all the other drop-downs too – even though that isn’t listed on their colour codes. There might be a good reason for it, but I don’t know what it is and this has confused other people too (me included).
However, after a little experimentation prompted by this thread, I have found you can turn them off if you wish. On the Line Type drop-down, down the right hand side there are visibility switches (eye icons). Turn off seams visibility and they disappear from the other views (eg Filament) as well.
