Loading filament on the Sovol SV08 starts in the knob menu rather than the slicer. Selecting Load Fil hands the temperature side of the job to the printer itself: the heating block ramps up to the target temperature for whatever material is set, and once it reaches that point the extruder motor, the E axis, begins turning to push filament down toward the nozzle. The only real job left for the user is to watch the nozzle tip. A clean, steady string of filament coming out means the load worked. If nothing appears once the routine finishes, the manual’s guidance is simple: run Load Fil again rather than troubleshooting mid cycle.
The simplicity stops there, though. The manual covers loading in detail but never lays out a separate, named unload procedure with its own steps. In practice, changing filament on this machine probably means retracting the old strand first, however that is normally done on a Klipper based printer, then running the same Load Fil routine for the new material. Treat that as a reasonable pattern rather than a documented one, since Sovol has not published a distinct unload walkthrough to confirm the exact sequence.
For anyone who prefers watching to reading, Sovol keeps a video on its wiki called SV08 Filament Replacement Tutorial that covers the physical side of a filament swap. It is worth pulling up the first few times, particularly to see how much resistance is normal when pulling old filament back out.
Not every failed load traces back to a simple reload, either. Sovol’s troubleshooting index lists Unable to extrude the filament as its own separate entry, which suggests the company treats extrusion failures, things like a clogged nozzle or a slipping extruder gear, as a distinct category from cold or misfed filament. If a second or third Load Fil attempt still produces nothing, check that entry next rather than repeating the same routine indefinitely.
Loading filament on the SV08 follows the same Load Fil routine every time, from the knob menu to a steady stream at the nozzle. For general storage advice that keeps spools dry between prints, see the filament storage guide. If you’re setting the printer up for the first time, the SV08 setup guide covers what to check before that first load, and the SV08 first print walkthrough covers what comes right after.
