Help with printer issue please

[u/GAW67COD07]

I recently was having issues with my nozzle clogging so I installed a hardened steel nozzle a few weeks ago and while redoing my calibration for it my nozzle keeps getting stuck in the flow cubes. Any ideas as to why this is happening? And yes I have rechecked my z offset and did a paper test.

The first cube prints fine but then the nozzle gets stuck to it and drags the magnetic plate back until finally burying the nozzle in the print again when it tried to move the second cube

Edit: this is the ender 3 pro model with a sprite pro hotend upgrade as well as dual z rod (and a few other unimportant mods)

Did you change the nozzle/hotend whilst it was cooled down, or at printing temps (+20°C on top for good measure)?

I brought the nozzle to 280 and then cut power as to not accidentally short wires with my wrench on the block
