Prusa Mini+ with E3D Revo Micro & ObXidian Nozzles

Specialized knowledge for printing on a modified Prusa Mini+ with E3D Revo Micro hotend and ObXidian wear-resistant nozzles in 0.25mm, 0.4mm, 0.6mm, and 0.8mm sizes.

Hardware Specifications

| Component | Specification | |-----------|---------------| | Printer | Prusa Mini+ | | Build Volume | 180 × 180 × 180 mm | | Hotend | E3D Revo Micro (40W HeaterCore) | | Thermistor | Semitec 104NT-4-R025H42G | | Nozzles | ObXidian 0.25mm, 0.4mm, 0.6mm, 0.8mm | | Max Hotend Temp | 300°C | | Filament Diameter | 1.75mm | | Drive System | Bowden with direct drive extruder |

Nozzle Selection Guide

| Nozzle | Best For | Trade-offs | |--------|----------|------------| | 0.25mm | Fine detail, text, miniatures | Slowest, avoid abrasive filaments | | 0.4mm | General purpose, balanced | Standard, most profiles available | | 0.6mm | Faster prints, structural parts | Less detail, +25% impact strength | | 0.8mm | Rapid prototyping, large objects | Least detail, fastest, best for abrasives |

When to Use Each Nozzle

0.25mm - Miniatures, small text, jewelry, precision parts

  • ⚠️ Avoid filled filaments (particles often >0.25mm)
  • ASA and ABS work best with small nozzles per E3D

0.4mm - Default for most prints, prototypes, mixed detail

0.6mm - Structural parts, functional prints, moderate abrasives

0.8mm - Large objects, vases, rapid prototypes, heavy abrasives (CF, GF)

  • Best choice for filled filaments—lowest clog risk
  • May need 60W HeaterCore for high-temp materials at high flow

E3D Official Starter Settings

These are E3D's conservative starter settings for Revo hotends. Track width = extrusion width ≈ nozzle diameter.

PrusaSlicer Configuration

Printer Settings (per nozzle)

| Setting | 0.25mm | 0.40mm | 0.60mm | 0.80mm | |---------|--------|--------|--------|--------| | Nozzle diameter | 0.25 | 0.4 | 0.6 | 0.8 | | Min layer height | 0.06 | 0.10 | 0.15 | 0.20 | | Max layer height | 0.20 | 0.32 | 0.48 | 0.64 | | Retraction length | 3.0mm | 3.5mm | 4.0mm | 4.5mm | | Retraction speed | 35 mm/s | 35 mm/s | 35 mm/s | 35 mm/s | | Lift Z | 0.15mm | 0.2mm | 0.2mm | 0.3mm |

Built-in Profiles

PrusaSlicer has profiles for multiple nozzle sizes:

  1. Configuration → Configuration Wizard
  2. Select "Original Prusa MINI+"
  3. Check boxes for each nozzle size (0.25, 0.4, 0.6)
  4. 0.8mm: Create manually based on 0.6mm profile

Nozzle Swap Procedure

Revo quick-swap (no tools, no hot-tightening):

  1. Cool down below 50°C
  2. Unscrew current nozzle by hand
  3. Install new nozzle, finger-tight only
  4. Update slicer - select correct nozzle profile
  5. Re-calibrate - run First Layer Calibration
  6. Verify - print test square

⚠️ Each nozzle needs its own Live Z calibration!

Speed Calculation

Max Speed (mm/s) = Max Flow (mm³/s) / (Layer Height × Line Width)

Examples at E3D Medium profile:

| Nozzle | Layer | Width | E3D Wall | E3D Infill | |--------|-------|-------|----------|------------| | 0.25mm | 0.125mm | 0.25mm | 25 mm/s | 50 mm/s | | 0.40mm | 0.20mm | 0.40mm | 25 mm/s | 50 mm/s | | 0.60mm | 0.30mm | 0.60mm | 25 mm/s | 50 mm/s | | 0.80mm | 0.40mm | 0.80mm | 25 mm/s | 50 mm/s |

Note: E3D settings are conservative. Prusa Mini+ can often handle faster speeds.

ObXidian Nozzle Care

All sizes:

  • E3DLC coating: Non-stick, reduces buildup
  • Copper alloy body: Brass-equivalent thermal performance
  • Tool steel tip: Wear-resistant
  • Max temp: 300°C
  • Install: Finger-tight only, no tools

Size-specific guidance: | Nozzle | Abrasive Filaments | Clog Risk | |--------|-------------------|-----------| | 0.25mm | ❌ Avoid | High | | 0.40mm | ⚠️ Light use | Medium | | 0.60mm | ✅ Good | Low | | 0.80mm | ✅ Best choice | Very Low |
