Extruding problems
Hotend, nozzle and poor flow checks
Before replacing parts, check nozzle condition, filament path, hotend temperature stability, tension, heat creep and recent changes to slicer settings.

Support routes that reduce guesswork.
Electronics
Control board, wiring and firmware checks
Duet3D and other controller faults are easier to diagnose when wiring, power, firmware version, error messages and recent hardware changes are recorded first.

What to include when asking for help
Send the 3D Printer model, fault symptoms, clear photos, fitted parts, firmware details and what changed before the fault appeared.

Support articles by problem type.
Blocked nozzle or poor flow
Look for worn nozzles, partial clogs, incorrect temperature, heat creep, damaged PTFE paths, incorrect tension and unsuitable filament before replacing the whole toolhead.
Browse nozzles and hotendsLayer shifting, belts and motion faults
Check belt tension, pulley grub screws, motor wiring, driver current, loose frames, obstructions and slicer acceleration settings before assuming a motor has failed.
Browse motion partsFirmware or controller setup
When using Duet3D or RepRapFirmware, keep a copy of your config files, note the board model, firmware version and any exact error messages shown on screen.
Open Duet3D Config ToolHotend conversions and upgrades
Conversions work best when mounts, wiring, thermistors, heater cartridges, firmware limits, fan ducts and nozzle lengths are planned together.
Plan a conversionPrint quality and calibration
First layers, flow rate, pressure advance, retraction, temperature, cooling and mechanical play can all affect print quality. Change one thing at a time.
Ask for diagnosisChoosing compatible parts
If a product page does not make compatibility obvious, ask before ordering. Machine family, toolhead revision and previous upgrades can change what fits.
