I woke up to see the print was being pushed around and clogging the module. I tried to limit how much force to clear out the hard and semi goo PLA crammed inward but saw a wire from the nozzle waa detached afterwards, changed the nozzle and new pla loaded fine but when running an auto calibrate it’s a bit off as you can see in the video.

Guessing the sensor was damaged when I pulled off a print fail but figured I’d check here before ordering a new module, the original I have seems to be one that had the defective filament reader switch anyways.

Any thoughts or recommendations?  
Top pic is precleanout (I was using black pla which made it look much worse) and bottom pic is after getting pla and the nozzle out.

Did you just change the nozzle or the whole hotend?  
If the whole hotend is changed, make sure that it is neatly inserted into the groove above, otherwise the nozzle is too deep.
