Anet A8 upgrade!
The laser cut frame relies on washers under the bed to hold part of it together. When those washers slip loose the whole thing twists making leveling a nightmare. So I ordered an extruded aluminum frame, had my brother print the parts. Dissasembled the entire thing and took over the dinning room table to reassemble it. I also switched to prusaslicer (from cura) and have the settings dialed in I think (at least for hatchbox black) I did a print in place of this articulating Caterpillar and it went beautifully.
I still need to upgrade the firmware and some cable management… but I rebuilt a 3d printer and got excellent results.
