I’ve been having some issues with prints done on my 660. Brown colours come out very green. That’s it though, all other colours come out just fine. So far I’ve changed all print heads except black, purged and aligned them, and cleaned the pogo pins. I perform the regular maintenance suggested by the user guide after every print, (clean parking caps, service station, and fast axis rails)

Any suggestions would be great, thanks.

3D systems binder or knock off?
