PLA Retraction Settings for Bowden Tube: Values and Tests
Start PLA on a Bowden printer at 5 mm retraction and 40-60 mm/s, then tune with a 1-6 mm tower. Slicer fields, pressure advance and hardware fixes.

Best Slicer Settings Profile for Ender 3 V3: PLA and PETG
Stock OrcaSlicer values for the Ender-3 V3, the volumetric cap that sets your speed, and tuned PLA and PETG starting points to calibrate from.

3D Printer Calibration Order: What to Tune First
This 3D printer calibration order starts with mechanical checks and bed leveling, then covers e-steps, temperature, flow, pressure advance, and retraction.
-
Pressure Advance Calibration: Klipper and Marlin K Factor
Calibrate pressure advance in Klipper (including smooth time), Marlin Linear Advance M900 K and OrcaSlicer to fix bulged corners and starved line starts.

How to Level a Bed With BLTouch: Marlin and Klipper Guide
How to level a bed with BLTouch in Marlin and Klipper: mechanical tramming, mesh leveling, Z-offset tuning, and the traps that silently skip the mesh.
-
Ender 3 E-Steps & Steps per mm: Exact Values and Calibration
Find documented Ender 3 steps per mm, read the active E value, calibrate with Marlin G-code, save to EEPROM and check firmware differences by model.

How to Fix Stringing on 3D Prints: Retraction Settings
Stringing comes from retraction, temperature, and travel speed. Starting values for direct-drive and Bowden setups, plus a calibration sequence that works.
-
Bed Leveling: Manual vs Auto and How ABL Probes Work
What bed leveling actually corrects, how manual and automatic leveling differ, and how inductive, capacitive, and touch probes sense the bed surface.
-
Nozzle Size and Layer Height: How to Choose Both Together
Nozzle diameter and layer height are not independent settings, because one constrains the other. How to pick both for detail, strength, or print speed.
-
Print Speed vs Quality: Where Input Shaping Changes the Math
What actually limits print speed, why fast printers do not all show ringing, and how input shaping and pressure advance change the speed-quality trade.
-
Flow Rate Calibration: Slicer Tests and Dimensional Accuracy
Calibrate flow rate in OrcaSlicer, PrusaSlicer, Cura and Klipper with worked calculations, a defect lookup table and dimensional verification steps.
-
Filament Dry Box vs Heated Chamber: Calibration Setup
Separate filament drying, dry-box feeding and heated print chambers, then keep spool condition and enclosure settings consistent during calibration.
-
Extruder Calibration: How to Tune and Verify E-Steps
E-steps decide how much filament your printer really extrudes. Measure, calculate, and set the correct value, then verify it with a second test print.
