QIDI Slicer – Precision 3D Printing Made Simple

Q: Where do I download the latest QIDI Slicer safely?

Use the official GitHub Releases page for versioned installers (Windows/macOS/Linux) and the QIDI Wiki for overview/links. Avoid third-party mirrors.

Q: macOS says “App can’t be opened”—how do I run QIDI Slicer?

In System Settings → Privacy & Security, click Open Anyway for QIDISlicer, then Open when prompted. This allows the trusted app while keeping Gatekeeper enabled.

Q: On Ubuntu 24.04, QIDI Slicer 1.2.x crashes with a libsoup2/3 error. What should I do?

Prefer the AppImage build when available or temporarily roll back to a stable earlier release (e.g., 1.1.7) while monitoring newer releases for fixes.

Q: My Z-offset is different when I start prints from QIDI Slicer vs. Fluidd. How do I make them match?

Unify Start G-code so bed mesh and Z-offset are applied only once. In Klipper, calibrate bed mesh, save, and load the profile once in Start G-code; avoid duplicate offsets.

Q: Does QIDI Slicer support tree/organic supports? How do I enable them?

Yes. QIDI Slicer (PrusaSlicer-based) includes Organic supports in newer builds. Select Support style: Organic, then tune interface and Z-gap for easier removal.

Q: Supports fuse to my PLA model when I choose “Everywhere.” How can I remove supports cleanly?

Use Touching build plate, add a dense support interface, increase Support Z-distance slightly, and consider Organic style for less contact.

Q: I can’t upload/print over Wi-Fi from QIDI Slicer. What’s the best workaround?

Export G-code and print via USB/SD for reliability. Update to the latest slicer—point releases often fix Send/UI issues.

Q: Is QIDI Slicer compatible with OrcaSlicer/PrusaSlicer profiles?

Broadly yes—settings map well. After importing, always verify Start/End G-code and revalidate flow, retraction, and speeds on a small test print.

Q: QIDI Slicer crashes or can’t open project files—what quick checks should I try?

Update to the latest release, reset your local config so the app rebuilds defaults, and re-export the model as STL/3MF from CAD.

Q: What’s the simplest, most reliable way to go from model to print on QIDI?

Import → choose printer/material → slice & preview → export G-code → print via USB/SD. It avoids network/driver pitfalls for new setups.

QIDISlicer 1.2.5 Sep 04, 2025 V1.2.5 All Releases

Getting Started with QIDI Slicer

Install, configure, and achieve reliable results quickly. This expanded guide balances speed, quality, and repeatability, with clear choices when trade-offs are required.

Check Requirements

Component	Recommended
OS	Windows 10/11, macOS 12+ (Monterey or newer), or a current Linux distro (Ubuntu/Fedora/Arch)
CPU	64-bit dual-core+ (quad-core improves slicing/preview performance)
RAM	8 GB (16 GB for large organic meshes or high-poly scans)
GPU	Integrated is fine; a discrete GPU speeds previews with dense supports
Disk	1–2 GB free + room for model libraries and G-code archives

Printer readiness: Verify the correct nozzle installed (typically 0.4 mm brass/hardened), stable bed hardware, and clean build plate. If your model has a firmware updater, run it before your first long print.

Download & Install

Use the Downloads section on this site (curated from official releases) or go directly to the GitHub page. Prefer the installer for your OS; portable builds are useful if you lack admin rights.

Download (Recommended) GitHub Releases

Windows: Run the .exe installer; if blocked by SmartScreen choose More info → Run anyway. Use the .zip only for portable use.
macOS: Open the .dmg, drag the app to Applications. If Gatekeeper warns you, open via System Settings → Privacy & Security → Open Anyway.
Linux: Prefer .AppImage (set executable: chmod +x), or install .deb/.rpm for your distro.

Security tip: Download only from the official links above. Avoid random file-sharing sites.

First Launch Setup

Pick your language and confirm where profiles will be stored.
Enable auto-update checks so you’re notified about slicing improvements.
Telemetry is optional; disabling it doesn’t limit features.

Add Your Printer

Go to Printers → Add and select your exact QIDI model. If it isn’t listed, choose Custom FFF and set:

Build volume: X/Y/Z per your printer spec
Nozzle dia: 0.4 mm (unless you installed a different size)
Filament: 1.75 mm
Start/End G-code: use manufacturer defaults if available.

Factory profiles include sane speeds/accelerations and retraction baselines. You can create variants for quality vs speed later.

Load Filament & Choose a Profile

Load the filament at the nozzle temperature indicated on the spool. Select a material preset (PLA, PETG, ABS, TPU) and a quality target (Draft/Standard/Fine). These presets tune temperatures, cooling, and baseline speeds for that plastic.

Keep filament dry—store with desiccant. PETG/TPU absorb moisture quickly and string more when humid.
Match bed surface to material (e.g., smooth PEI for PLA; textured PEI or glue stick for PETG to prevent sticking too hard).

Level the Bed (First-Layer Success)

Clean the plate with 90–99% IPA. Remove oils and dust.
Run your printer’s auto-level or manual 4-corner tramming.
Print a first-layer grid. Adjust Z-offset in 0.02–0.05 mm steps until lines are slightly squished and continuous.

Too high Z → poor adhesion/gaps; too low → elephant skin and nozzle scuffing. Aim for smooth, joined tracks with a satin sheen.

Import, Orient & Arrange Models

Drag in .STL/.3MF/.OBJ. For assemblies, 3MF keeps parts grouped and materials.
Rotate so a flat face rests on the bed; avoid overhangs exceeding your support threshold.
Scale to fit; maintain 2–5 mm spacing between parts for skirts and clean toolpaths.
Use Auto-arrange for multiple parts to reduce travel and stringing.

Quality, Walls & Infill (Dial-in)

Layer height: 0.2 mm (general), 0.12–0.16 mm (fine), 0.24–0.28 mm (draft).
Perimeters: 2–3 for most parts; 4+ for functional strength and better top surfaces.
Top/Bottom: Top 5–7 layers prevent pillowing; bottom 3–5 layers ensure base rigidity.
Infill: 12–20% for shells/models; 30–60% for load-bearing; Gyroid/Cubic for balanced isotropy.

Use finer layers only where visible. For internal geometry, coarser layers save time with minimal visual impact.

Supports & Bed Adhesion

Supports: Start with “Touching build plate”. Use support interface for clean undersides; increase support Z-gap slightly if removal is difficult.
Adhesion: Skirt (2–3 lines) to prime extrusion. Brim for tiny contact patches or warping plastics. Reserve rafts for extreme warping only.

Cooling, Retraction & Speed

Cooling: PLA high fan; PETG moderate (too much → brittle layers); ABS minimal with enclosure.
Retraction: Direct drive baseline ~0.8–1.2 mm @ 25–35 mm/s; adjust in small steps to reduce stringing without causing jams.
Speeds: 40–60 mm/s standard; slow outer walls for surface quality; keep first layer slow (15–20 mm/s).

Preview & Validate Toolpaths

Use the layer preview to confirm:

First-layer lines are continuous and evenly squished.
Support contact points are minimal but adequate.
Bridges have fan/cooling and reasonable speeds.
Thin walls aren’t skipped; switch to “Line width view” if available.
Time and filament estimates match expectations.

Export & Start the Print

Name files descriptively (e.g., gearbox_cover_PLA_0p2_3walls.gcode).
Transfer via SD/USB or network (if supported). Verify correct file before starting.

First-Layer Checks (Live)

If edges lift, add a brim, increase bed temp slightly, or improve enclosure/room draft control.
If under-extruded, re-seat filament, increase nozzle temp by 5 °C, check that the drive gear bites cleanly.

Material Baselines

Material	Nozzle / Bed	Cooling	Notes
PLA	200–210 °C / 55–65 °C	High	Easy & stable. Great for models and fixtures.
PETG	230–245 °C / 70–85 °C	Medium	Tough and slightly flexible. Dry well to reduce stringing.
ABS/ASA	235–255 °C / 90–110 °C	Low	Needs enclosure; strong and heat-resistant; watch for warping.
TPU	210–225 °C / 40–55 °C	Low	Slow speeds (20–35 mm/s), minimal retraction; ensure clean filament path.

Troubleshooting (Fast Fixes)

First layer not sticking

Re-clean plate; brim +5–10 lines; lower Z-offset slightly; increase first-layer flow to 105–110%.
Slow first layer to 15–20 mm/s; raise bed temp by 5 °C.

Stringing

Dry filament; increase retraction distance/speed gradually; lower nozzle temp by 5–10 °C.

Weak parts / splits

Raise nozzle temp slightly; add perimeters; reduce cooling (ABS/PETG); increase wall overlap if available.

Surface artifacts

Slow outer walls; enable “ironing” (for flat tops) sparingly; ensure belts are tensioned and wheels not loose.

Fine-Tune Like a Pro

Expert Tools Iterate in small steps

Variable Layer Height (Detail Where It Matters)

Goal: Apply fine layers to curved/visible areas and coarse layers elsewhere to save time without sacrificing finish.

Enable Variable/Adaptive Layer Height. Set Min (e.g., 0.12 mm) and Max (e.g., 0.28 mm).
Use a higher curvature threshold so only steep geometry gets fine layers.
Preview and confirm only domes, fillets, and logos refine; infill stays coarse.

Use case	Min/Max	Notes
General models	0.16 / 0.28 mm	Balanced quality/time
Miniatures	0.10 / 0.20 mm	High detail on faces
Drafts	0.20 / 0.32 mm	Fast iterations

Use the layer preview scrubber to ensure only curved regions get finer layers.

Adaptive Infill (Strength Where Loads Concentrate)

Goal: Put density where it adds strength (around fasteners, thin posts, load-bearing spans) while keeping the rest light.

Start with Gyroid or Cubic at 12–20% for cosmetic; 30–60% for functional parts.
Enable adaptive/density scaling near top/bottom or stress zones if available.
Use per-model modifiers (A3) to locally raise density.

Per-Model Modifiers & Local Overrides

Add a modifier mesh (box/cylinder or imported STL) intersecting the target area.
Override settings inside the modifier (e.g., higher infill, more perimeters, different layer height).
Preview to verify only the overlapped region changes.

Reinforce screw bosses, clamp faces, or hinge points without penalizing the whole part.

Advanced Supports (Clean Undersides, Easy Removal)

Style: Try Tree supports for organic shapes; grid for predictable bridges.
Interfaces: Enable a denser interface for smooth undersides; tune Z-gap for easy break-off.
Painting/Blockers: “Paint” supports only where needed; add blockers on cosmetic faces.
Angles: Start at 50–55°; adjust by material and bridging ability.

Surface Tuning (Seam, Ironing, Line Width)

Seam placement: Hide on a rear edge or corner; random seams reduce zits but can dimple surfaces.
Ironing: For glossy tops, low flow & slow speed; use sparingly to avoid ripples.
Line width: 110–115% improves bonding; wider first layer improves adhesion.

Target	Setting
Hide seam	Corner/back; reduce “extra prime”
Glossy tops	Enable ironing; slow outer walls
Strong walls	Line width 110–115%; 3–4 perimeters

Speed, Acceleration & Jerk (Quality vs Throughput)

Walls: 40–60 mm/s; Infill: 80–120 mm/s if extrusion keeps up.
Acceleration: 500–1500 mm/s² for walls (higher for infill). Lower if ringing appears.
Jerk/corners: Reduce jerk or enable “slow small perimeters” for crisp edges.

Pressure Advance / Linear Advance

What it does: Compensates extrusion pressure lag for sharper corners and dimensional accuracy.

Klipper: Calibrate pressure_advance via PA test and update printer.cfg.
Marlin: Calibrate K-factor with an LA tower; save to EEPROM.
Re-tune for different filaments, temps, and nozzles.

Use only if firmware supports it—incorrect values can cause artifacts.

Calibration Workflow (Rapid, Repeatable)

Temp tower: Pick the segment with best bonding and least stringing.
Retraction tower: Increase distance/speed until strings vanish without gaps.
Flow/EM: Single-wall cube measured thickness ≈ line width.
Speed/Accel: Raise until ringing appears, then step back.

Save each success as a versioned profile (e.g., PLA-Std-2025-09).

Profile Management, Versioning & Print Farms

Versioned names: include material, quality, and date (e.g., PETG-Fine-2025-09).
Export/backup: keep profiles in cloud/VCS; weekly mini-benchmark to catch drift.
Consistency: standardize filament brands/colors across machines for predictability.

QIDI Slicer – Frequently Asked Questions

Official links & safe installs We monitor new releases

Where do I download the latest QIDI Slicer safely?

Two safe sources:

GitHub Releases (changelogs, versioned installers for Windows/macOS/Linux).
This Website. Use these to avoid mirrors and repacks.

macOS says “App can’t be opened”—how do I run QIDI Slicer?

QIDI Slicer isn’t notarized in some builds. On macOS 12+:

Open System Settings → Privacy & Security.
Scroll to “Security” and click Open Anyway for QIDISlicer.
When prompted, click Open.

This keeps Gatekeeper active while allowing this trusted app.

On Ubuntu 24.04, QIDI Slicer 1.2.x crashes with a libsoup2/3 error. What should I do?

This is a known conflict when both libsoup2 and libsoup3 symbols load in one process. Workarounds observed by users:

Prefer the AppImage build when available.
If blocked, try an earlier stable release (e.g., 1.1.7) and watch the latest release notes for fixes.

Always test on a fresh user profile if you upgraded in place.

My Z-offset is different when I start prints from QIDI Slicer vs. Fluidd. How do I make them match?

Ensure you’re not applying Z-offset or bed-mesh twice. Tips:

Standardize your Start G-code (either let the firmware apply mesh & offset, or let the slicer call it—never both).
In Klipper, run BED_MESH_CALIBRATE and save; call BED_MESH_PROFILE LOAD=default once in Start G-code.
Avoid “babystepping” offsets in one workflow that aren’t persisted to the other.

Does QIDI Slicer support tree/organic supports? How do I enable them?

Yes—QIDI Slicer is based on PrusaSlicer, which includes Organic (tree-like) supports. In most builds, you’ll find it under Support style as Organic. If your version predates the feature, update to a newer release.

Use Interfaces for cleaner undersides.
Increase Support Z-gap slightly if removal is difficult.
Paint supports only where needed to cut material/time.

Supports fuse to my PLA model when I choose “Everywhere.” How can I remove supports cleanly?

Switch to Touching build plate for many helmet/overhang models.
Enable a support interface and increase interface density.
Raise Support Z-distance slightly (and lower nozzle temp 5–10 °C if stringy).
Test Organic supports for reduced contact.

I can’t upload/print over Wi-Fi from QIDI Slicer. What’s the best workaround?

Network tools vary by firmware and are evolving. If “Send” fails or is greyed out, use a reliable path:

Slice → Export G-code.
Copy to USB/SD and print locally; confirm file name matches.
Update to the latest slicer release; several “Send”/UI fixes land in point releases.

Is QIDI Slicer compatible with OrcaSlicer/PrusaSlicer profiles?

Yes in principle—QIDI Slicer is a fork aligned with PrusaSlicer’s ecosystem; many settings map cleanly. Community users also run OrcaSlicer successfully on QIDI printers. Always verify machine g-code sections (Start/End) and flow/retraction after importing profiles.

QIDI Slicer crashes or can’t open project files—what quick checks should I try?

Update to the latest release (point releases often fix import/UI bugs).
Start with a fresh profile (rename/delete the local config folder to let the app recreate it).
Test the model as .STL or .3MF freshly exported from CAD.

What’s the simplest, most reliable way to go from model to print on QIDI?

Import .STL/.3MF → choose the correct printer & material profile.
Slice → check preview (first layer, supports, bridges, time/filament).
Export G-code → copy to USB/SD → print from printer menu.

It’s basic—but consistently avoids network/driver pitfalls for new setups.
