Sovol Zero Slicer Profiles for OrcaSlicer, PrusaSlicer & SuperSlicer + Klipper Macros: Faster Chamber Heating, Quiet Exhaust

Profiles for the Sovol Zero in OrcaSlicer, PrusaSlicer and SuperSlicer, generated from one source so all three slicers ask for the same speeds and accelerations. An optional Klipper macro pack adds bed boost for the chamber preheat, a quiet PID exhaust fan, a nozzle brush routine, a purge ring, a scheduled bed cooldown and, on 1.3.7, a first-layer lift for nozzle growth.

Which file

Download the ZIP for your slicer. Each one includes INSTALL.md and the optional macro pack.

• OrcaSlicer: copy profiles/SVZero.json and profiles/SVZero/ together into Orca's system/ folder, then enable SV Zero in printer selection.

• PrusaSlicer and SuperSlicer: File > Import > Import Config Bundle, and pick SVZero_PrusaSlicer.ini or SVZero_SuperSlicer.ini.

What you get

• 10 nozzle sizes from 0.2 to 1.4 mm, with 56 print presets from Fine to Draft

• Brass and hardened steel filament presets for PLA, PLA Silk and PETG, plus ABS, PC, PCTG and TPU

• Accelerations scaled to the Zero's measured input-shaper limits, 11,500 mm/s² on X and 6,000 on Y, with every feature in each tier kept in proportion

• Draft runs its infill at the 21 mm³/s PLA flow cap instead of asking for more and being clipped

• Shrinkage compensation for each material, in XY and Z

• A precision mode for slow, quiet, fine-detail prints on the 0.4 nozzle and below: layers from 0.04 mm at 64 microsteps and 1.4 A

• A bed preview built from Sovol's own hotbed CAD, lead screws included, with Chinchill's buildplate texture (CC BY 4.0)

Klipper macro pack

The profiles work on stock Sovol firmware without it. One consolidated file for 1.3.7 or 1.4.x adds:

• A quiet PID exhaust. The fan throttles to hold the chamber instead of switching between off and 80% the way stock 1.4.x does, which is loud and leaves horizontal bands. On my Zero it held the chamber within about half a degree with the fan at 30-36%, never off, and at its loudest it was about 11 dB quieter than stock's 80%.

• An M191 chamber soak that parks the plate where it heats the chamber best and stirs with the part fan, which doubles what the bed gives up.

• Bed boost, with the Python helper. The bed runs up to 120 °C while the chamber climbs and is back at print temperature before the soak ends, timed from past waits on your own printer. M191 waits on the air at the stirred nozzle rather than the rear sensor. On my Zero, from a 27 °C box, it halved the ABS soak: 13.3 minutes against 25.6 with the bed at 100.

• Nozzle growth compensation on 1.3.7. The tare-tap takes Z with the nozzle at 150 °C, and a hotter nozzle reaches further down, about 0.14 mm at ABS's 280 °C on my Zero. The first layer is lifted by 1.1 µm per °C above 150: +0.09 mm for PLA up to +0.14 mm for ABS. Off on 1.4.x.

• A nozzle brush routine for the silicone pad, which needs commissioning for your pad

• A purge ring with no start blob

• A lower X/Y stepper current, 2.4 A on Fine to Strength against stock's 3.5, set at print start and put back after

• A 5-133 Hz input-shaper test, which also fixes the front screen's Resonances test (stock sweeps 35-45 Hz, and the Zero's X axis sits near 61)

• A bed cooldown at 2 °C/min that brings in the exhaust and then the curtain fan, weighted by how hard each was measured to cool the plate

• A runout check that refuses a job with no filament at the sensor before anything heats

• An optional Spoolman check of material and remaining filament before heating

Tested so far

My 1.3.7 Zero, 218 automated tests, and a headless slice of every nozzle, tier and filament in all three slicers. The nozzle growth lift came from tap pairs beside the bed's sensor and from single-layer ABS squares printed at four lifts on that Zero. An ABS benchy then printed start to finish on the 2.1.2 macros with the lift. On 1.4.x, one owner's report so far: the nozzle clean fix let their print start. Not yet printed: Brass and Steel's new temperatures, PCTG, scarf seams on holes, the 2.1.1 accelerations and lower stepper current, prints on the 0.25 and 0.3 nozzles or in precision mode below 0.4. Not yet tried: Windows and macOS installs. The shrinkage values are nominal per material.
