MK3S+ Extruder clicking sound

Been busy and hasn’t been able to print much in the last year. Yesterday I updated all the firmware on my mk3s+ and mmu2s. I’m trying to print and I’ve tried different plates and filaments and everything keeps either clogging or when it does print the extruder makes an awful clicking sound and it’s skipping when printing. Any ideas on why it’s clicking and struggling to print consistently without skipping? TIA

The three common reasons for prints suddenly failing after a printer has been unused for a while:

A dirty print bed. Give it a really thorough clean and avoid touching the print area.

Damp filament. Look up threads here about drying filament especially if it has been left open.

General neglect, dust and cobwebs... Basic cleaning, lubrication and general maintenance have all been missed.
