Thanks for your replies! It turned out it was that the nozzle was not screwed on tight enough, as you said Chris Cheers

Hi guys I printed some models overnight last night in white PLA, and when I checked them this morning I found there are some green bits mixed in with the print. It's a similar colour to the machine's lubricant but it's hard. I changed the nozzle and cleaned the tube yesterday so I'm not sure what it is. This morning I extruded a bit of the material and it came out clean so I started another print but the same thing seems to be happening again. Has anyone ever experienced this or know what might be causing it? Thanks!
