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!
