The Sovol SV07 is a fast bedslinger with a Klipper brain, and its stock profiles are optimistic. Sovol’s own vendor profile ships 230°C and 8,000 mm/s² acceleration; the community presets that people actually print with are more conservative. This is what the community runs for PLA, what we run in the shop, and where the two differ.

The numbers
| Setting | Community / vendor | Shop (live) | Verdict |
|---|---|---|---|
| Nozzle temp, PLA | 205–230°C. Sovol vendor default 230°C; CV Jayo PLA preset 215°C (range 205–215°C) | 220°C first layer, 215°C rest | No conflict. Inside the band; 215°C matches CV exactly. |
| Bed temp, PLA | 55–65°C. Sovol default 55°C; CV 55–60°C | 65°C first layer, 63°C rest | Mildly above consensus. Helps adhesion on this bed; expect slightly more elephant’s foot. 60°C is the standard value to try if adhesion is fine. |
| First-layer speed | 40 mm/s (CV sets all first-layer speeds to 40 mm/s so the presets work out of the box) | 25 mm/s | Slower than CV. Fine for adhesion; 40 mm/s is safe to try. |
| Print speeds | 150–180 mm/s is the practical sweet spot for quality; 250 mm/s is Sovol’s recommended max for accuracy; 500 mm/s is a marketing peak, not a usable quality speed | 80 mm/s print, 200 mm/s travel in the shop profile | Conservative. The hotend caps out around 250 mm/s anyway (see volumetric speed). |
| Acceleration | CV process default 8,000 mm/s². Clever Creations recommends dropping to 5,000 mm/s² with accel-to-decel 2,000 mm/s² to avoid missed steps and layer shifts | 4,500 mm/s², accel-to-decel 2,000 mm/s² | Matches the community safe zone. The 8,000 mm/s² process value is where the layer-shift reports come from. |
| Square corner velocity | Klipper default 5.0; 3.0 is the conservative community-typical value for a bedslinger | 3.0 | No conflict. (Klipper has no jerk setting; square corner velocity is the equivalent.) |
| Retraction (direct drive) | 0.5–0.8 mm at 40 mm/s; CV: 0.5 mm, 40 mm/s, min travel 2 mm, wipe on, z-hop 0.24 mm | 0.6 mm at 40 mm/s, z-hop 0.6 mm | No conflict. The 0.6 mm z-hop is above CV’s 0.24 mm but it is a stronger version of the same nozzle-scratch fix. |
| Pressure advance, PLA | 0.02–0.05 s. Sovol ships 0.036; CV ships 0.02 | 0.04 | No conflict. Middle of the band; confirm per spool with a tower. |
| Max volumetric speed | 18–20 mm³/s. CV: “The hotend can deliver filament up to 18–20 mm3/s — and that’s about 250 mm/s print speed” | 20 mm³/s | Confirmed. This is the real speed ceiling, not mm/s. |
| Cooling | Fan max 100%; CV: min 40%, max 100%, overhang 95%, fan off for the first layer | Per CV | No conflict. |
| Layer heights | 0.10 mm fine / 0.20 mm standard / 0.32 mm draft | 0.20 / 0.30 mm | No conflict. |
| Input shaper | MZV typical; X ~45–65 Hz, Y ~35–55 Hz for SV07-class machines. Re-measure with an ADXL345 if ringing appears | X 2hump_ei at 43.4 Hz, Y zv at 40.6 Hz (from the live snapshot) | Inside the ballpark. The SV07 ships with an ADXL345; mount it square, one screw per axis. |
What actually matters
- The volumetric cap is the speed limit. 20 mm³/s is the hotend’s flow ceiling. Asking the slicer for 300 mm/s just gets flow-limited; the 250 mm/s draft preset is the community ceiling for quality prints.
- Acceleration is where layer shifts come from. The SV07 is a bedslinger: the heavy Y bed rings lower than X and is the layer-shift suspect at high accel. Keep Y accel conservative. The shop caps (225 mm/s, 4,500 / 2,000 mm/s²) sit in the safe zone the community recommends.
- Calibrate rotation distance before trusting flow or pressure advance. CV requires it before any flow or PA value can be trusted. The shop extruder reads 40 — verify on your machine, don’t copy blindly.
- Pressure advance is per spool. 0.04 is a sensible middle value, but the correct way to confirm it is a tower (
TUNING_TOWER COMMAND=SET_PRESSURE_ADVANCE PARAMETER=ADVANCE START=0 FACTOR=.005). Klipper warns that values above 0.200 can skip steps. - Retraction and z-hop are cheap insurance. 0.6 mm at 40 mm/s with a 0.6 mm hop stopped the nozzle drag we were seeing. CV’s 0.24 mm hop in v1.5.5 was raised specifically to stop nozzle scratching.
Shop profile
The shop’s working OrcaSlicer preset is PLA 220/215°C, bed 65/63°C, 20 mm³/s volumetric cap, 80 mm/s print / 200 mm/s travel, retract 0.6 mm at 40 mm/s, 3 walls, 15% gyroid, 4 top / 3 bottom layers, 5 mm brim. The same numbers feed the print-time estimates in STLTools, which ships with a Sovol SV07 estimate profile.
None of this is a substitute for calibrating your own machine and filament. It is the starting point that the community data and our bench agree on.
