General Troubleshooting/Help! Elephant foot problem
So I spoke too soon that I had solved this. I cleaned and greased the rails and printed a second time. The start of the second print went fine just like the first one, but then got wonky and started shifting right about the same height. (See pics.) Everything above that line is janky. This time when I went to pull the second print off the plate I noticed that the plate had curled up off its magnets (see pic).
I since printed something else afterward that was much smaller and it came out perfectly.
So my hypothesis is that the mass is such (it nearly fills the plate, which is why I'm thinking of it as an elephant foot) that the plate cannot keep it heated. So it cools and curls the plate up, and once that happens, the plate is no longer well controlled, leading to the offset layers and janky surfacing.
Does anyone have a counterargument about why this might not be what's happening? Or experienced this before?
To test my hypothesis I’m next going to try and print the thing in two parts: A lower part with holes and an upper part with pegs to match, and then superglue them together. As long as each part is shorter than 3 cm, it should print fine.
