Last week I was printing with Cheetah, same settings as always and since the print was 18 hours I wen home (I have the printer at the office) then when I came back I found a huge mess!!! It took me about 5 hours to clean the mess, there was cheetah even "inside" the print core, so I was heating the printcore and removing what I could with a lot of patience. I managed to clean it and it looked ok. After that I printed Innofil PLA and ultimaker ABS, both with good results. Today I printed with cheetah again, a small piece (35 min) and I printed it from a printcore AA in the extruder number 2, since it is cleaner that the one in the extruder number 1. When I checked the printe it was printing ok, I left it alone for the last 10 minutes and...: There is a point when it starts to just extrude material and it sticks to the noozle, the material is even having the nozzle shape: I can see that the conditions change at some point, the part of the piece that I could save changes color after some good layers Does anyone has a clue of the reason for this annoying thing!?? I can really figure out why this is happening now if I do things as I always did... I hope someone can give some light to this topic... Have a great day makers!
