Here's a simple trick to get your Anycubic spool printing smoothly without those annoying jerks: try adjusting the retraction settings on your printer. Specifically, you want to lower the retraction speed and increase the retraction distance. This will help prevent the filament from getting tangled or jammed during printing, resulting in a round and smooth finish.
