Hey,

Still fairly new to this hobby and have lots of ideas but I've got a snag with a few prints now and was hoping someone could help me work out what I'm doing wrong.

The project is small trays for a custom advent calendar but as you can see the corner on the second picture has lifted massively.

A 3d printed tray in grey with a handle.

This has happened before with a different print too and I never solved that issue either.

Using an Ender 3 Pro with some generic filament from amazon, hot end at 200C (goes stringy any higher), bed was 50C for this print I think.

Any help would be wonderful :)

The shorter side on the X makes less air movement across the bed thus retaining more heat in a localized area. Think of all printer motions like little fans themselves. Moving a palm frond or paper fan moved in a large motion moves more air.

The moving bed and undesired cooling it causes is one of the largest weak spots in Cartesian printers.
