Bed leveling failed, Need Help!

Hi everyone,

I recently had a really bad print failure on my Prusa i3 MK3S which caused the filament to gather around my print head in a huge mess and it ended up melting some of my parts so I had to do a reconstruction of my extruder. It was mostly 3D printed parts, but my PINDA warped a little bit, so I got a new one to replace it and my hot end was a bit messed up so I got a new one for it as well.

After reassembling my extruder, I am running into an issue with the bed leveling during the initial calibration. The specific error message I am getting is: "Bed leveling failed. Sensor didn't trigger. Debris on nozzle?" With it being a new hotend, there is zero debris on the nozzle. I have also relubricated all of my posts and the Z screws, so that isn't it either. Here are some pictures and a video showing what's going on for reference.

Does anyone have any ideas? Thanks in advance for any help!

Check your Z motors. it looks like one side is not moving at the same speed as the other. regards Joan

It looks to me like the right side isn't moving at all.

Mine acted exactly the same way when initially assembled. I had plugged the right hand Z motor into the wrong jack on the EINSY.
