Does anyone know the screws used for the filament break detector in the extruder? According to Replace K2 Plus Filament Break Detection | Creality Wiki they are M2s but it seems like they’re smaller than that.
I had an issue where, on one piece of a multi-piece print, the nozzle was too close to the bed so no filament could come out. I stopped the print which resulted in a cutting error and jam. I cleared the jam and reassembled. Despite filament extruding into the waste shoot, I received a persistent extrusion error. I went to replace the filament sensor and lost a screw. I went to reassemble with a single screw holding it and lost the spring so I figured I might as well order replacement screws too.
I was looking at Amazon.com
But, and I could be mistaken, those seem to have a bigger head on the M2 variant.
