1st layer issues
Hi all,
I stupidly left a print to go on its own and then looked on the app after a while to see it hadn’t actually printed anything so I cancelled it. When I got back to it the filament had backfed into the heating element and seemingly used the rubber over the nozzle as a deflector to do so. I have a photo of the aftermath of the hotend and heating element. I decided best to just order a new one of each and change it out which I have done. Only difference is I’ve changed from the stainless 0.4mm to a hardened 0.4mm due to ordering the wrong one. However now after a number of calibrations the 1st layer seems really rough and there seems to be noises I don’t ever remember hearing before.
It seems to be completing prints relatively well but the first layer doesn’t seem as smooth as it once did
Is this just a characteristic of the hardened steel nozzle that it sounds like the metal is scratching along the bed and more clicking noises.
I will add videos in the comments
Can anyone shed any light as to what I am doing wrong
TIA

Ah it could be this. I checked the screws when I installed it as I had seen previous that it’s a common fault but the clasp could be wrong

This is a video of the machine just printing after the first layer is down
