[Closed] MK3s upgrade meltdown
Been using the upgraded MK3 for a month.
Was printing an ABS part when after leaving unattended for an hour or so, came back to see nothing coming out of extruder and R4 parts melted around the hot end. (see pix). Hot end remains clogged after many tries to remedy.
Would like to know how this happened so as not to repeat in the future.
Thanks ... Ted
I had the same issue. Did you ever find out what caused it to happen?
I will be tearing down the printer today and replace the melted parts.
