We got our TAZ 5 a few weeks ago and have made some parts on it that were all run mostly during the day. Last night we decided to run a slightly modified version of a part that we had run before and came in to find the printer as in the attached picture.
The first layer was under the build platform and there was a large blob of material you can see on the right side. Then it looks like at some point it was able to lay down a few layers that somewhat stuck together on top of the randomly extruded birds next. I can sort of understand if the base delaminated from the build platform and was able to move that the mess of material could have been caused but what I don’t understand is the blob, even if the Y axis jammed X would still have been able to move.
We used Cura ABS_cura_Medium_0.5TAZ profile downloaded from the lulzbot site with no changes. This is the same profile we used on the lat print as well and had no issues.
My biggest concerns now is can we clean the print head which is covered in burnt ABS.
