Filament clogging keeps after updating software
I upgraded my MK3s to 3.9 last year and all had been working fine until the more recent slicer & firmware updates where the filament now does its little retract dance at the end of the print. The filament now jams at the start of a new print and needs to be unloaded and cut before being reloaded from where it will print correctly until the next new print.
When it jams , the end of the extracted piece of filament is rougher, distorted and a fractionally thicker where it has melted which is why I assume it causes it to jam, and why a clean cut end doesn't have a problem.
So is there an update or an option to correct this because having to unload and reload the filament every time I want to print something is a pain.
Cheers
