 ==== Loading filament ====
+=== Normal filaments ===
 This printer features an auxiliary filament feeder, which feeds filament through 2 meters of bowden tubing to the (direct drive) extruder.

 The process is a bit more manual than I'd like, but oh well.
+=== Flexible filaments ===
+If your flexible print can fit on another printer, use them. If other printers are in use, wait for them to be available. Loading flexibles on this printer requires going through steps that have a high chance of damaging the printer if done incorrectly. If you have even a hint of doubt, stop and ask [[people:ar:start|ari]] for help. If you haven't done this before, and you haven't seen this done before, stop and ask [[people:ar:start|ari]] for help.
+This section is work-in-progress, as there have been few attempts at printing flexible filaments on this printer so far.
+The auxiliary filament feeder has proven detrimental for attempts at printing flexible filaments on this printer.
+To load a flexible filament:
+  * heat up the hotend to be able to push out the remains of whatever filament was loaded before.
+  * remove the toolhead front plate, taking care not to rip out the fan connector
+  * disconnect the reverse-bowden tube connecting the feeder to the toolhead. remember not to lose the bowden tube locking thingy
+  * push out the remains of the other filament with a thin metal rod, which should be present in the sovol maintenance parts box. a thin hex driver could also work
+  * change the hotend temperature to whatever your flexible filament requires
+  * with the idler arm loose, push the flexible filament through the extruder mechanism.
+  * close the idler wheel arm and screw it back in
+  * disable filament sensor in the printer interface.
+  * extrude filament by clicking through the printer interface until no remains of previous filament remain visible.
+  * close the toolhead front plate, remembering to re-connect the fan.
+  * secure the disconnected reverse-bowden tube and the bowden tube locking thingy.
+  * watch the first layer when starting a print, and make sure it's all actually sticking to the bed
+Remember to un-do the changes when print is finished.
 ==== Printer profiles ====
-Currently installed nozzle is hardened steel 0.4mm. Nozzles are in the general style of e3d v6 nozzles, and swapping them is possible, but extra care must be taken to not crack the ceramic heater. Because of the annoying procedure involving hot-tightening, I've ordered a second hotend module along with the nozzle set, with the intention of swapping the hotend to change between 0.4 and 0.8mm nozzles.

+OrcaSlicer since the release of version 2.3.1 has profiles for Sovol SV08 MAX.
+=== Profile fixes ===
+== Pause not working ==
+Until a version of OrcaSlicer with [[https://github.com/SoftFever/OrcaSlicer/pull/11214|profile fix]] gets released, users wanting to use "Pause at layer" feature straight from the slicer will need to make a manual profile change.
+  - Open machine settings
+  - Open "Machine G-code" tab
+  - Scroll down to the "Pause G-code" setting
+  - Write ''PAUSE'' in the text field.
-There are printer profiles provided by Sovol: [[https://github.com/Sovol3d/Sovol-OrcaSlicer/releases/download/v2.3.0.4/Sovo.Profilesl.zip]]

-<del>I've opened a [[https://github.com/SoftFever/OrcaSlicer/pull/10768|PR in OrcaSlicer]] to import the relevant ones for this printer into OrcaSlicer. Hopefully this will get merged in time to get included in v2.3.1 release.</del>The PR has been [[https://github.com/SoftFever/OrcaSlicer/pull/10768#event-19869625384|merged]]
+=== Filament profile tuning ===
-Importing "system" profiles in OrcaSlicer is rather annoying. Here's a naive approach to embed them at build time using Nix. Fair warning: this causes a rather lengthy rebuild:
+The default profiles for generic filaments are quite conservative/slow. Here's some experimentally-verified improvements:
+  * yellow Plastspaw PET-G (the same as used on huge pope meme print) + 0.8mm nozzle:
+    * Volumetric speed limitation -> Max volumetric speed -> 30mm³/s, default for "Generic PETG" is 15mm³/s
