Anyone else have the issue when you print a mostly white or bright coloured item, then for some reason half way through some rogue black or darker colour will just get blobbed into it randomly, where is this darker material coming from, seems to be stuck in the nozzle or something. No issues with flow or bed etc, it just seems as if there is a tiny bit in the nozzle which releases when it feels like, happens on all my A1s
That has happened to me, even after wiping the nozzle clean before the print starts. I think stray extruded filament must sometimes get stuck inside the silicone shoe, then ooze out during a print job.
