💡 How to prevent filament grinding during initial multi material extrusion sequences?
Most feed issues stem from improper tension calibration or misaligned gear teeth rather than the motor itself, making proper adjustment handy for steady output.
- Verify idler springs sit evenly across all active drive pathways
- Lubricate linear rails sparingly with PTFE compatible grease only
- Monitor heat block temperatures closely to avoid thermal creep issues
