Encoders on closed-loop stepper motors (e.g., BLDC motors in advanced extruders).
Precision temperature sensors (thermocouples) for heated chambers or nozzles.
Signal-Intensive Components:
Load cells (auto bed leveling strain gauges).
High-speed camera feeds for monitoring/AI error detection.
Why Coax Matters for Print Quality
EMI/RFI Shielding: Coax blocks electromagnetic interference (EMI) from motors, heaters, and power cables. Without this, sensors can send false signals → layer shifts, thermal errors, or print failures.
Signal Integrity: Maintains accurate data transmission over distance—critical for sensors far from the mainboard (e.g., chamber thermocouples).
Durability: Resists wear from continuous motion (e.g., on moving gantries).
When to Consider Coaxial Cable
Use coax if your printer has:
Closed-loop systems (e.g., Duet3D, BigTreeTech motor encoders).
High-temperature environments (>100°C) where standard cables degrade.
Frequent “thermal runaway” or signal errors despite troubleshooting.
Choosing the Right Coaxial Cable
Feature
Ideal for 3D Printers
Avoid
Impedance
50Ω or 75Ω (match sensor specs)
Mismatched impedance
Shielding
Dual-layer (foil + braid)
Single-layer shielding
Jacket
Silicone (flexible, heat-resistant)
PVC (stiff, melts easily)
Connectors
Gold-plated (resists oxidation)
Cheap tin-plated types
Recommended Types:
RG-174: Thin, flexible. Perfect for encoders.
RG-316: Higher heat resistance (200°C). Ideal for chamber sensors.
Installation Tips
Route Away from Power Cables: Cross coax/power at 90° angles to minimize interference.
Secure Strain Relief: Use clips or zip ties near connectors to prevent tug damage.
Test Continuity: Multimeter check post-install (signal-to-shield resistance should be >1MΩ).
Troubleshooting Coax Issues
Symptoms of Failure:
Erratic bed leveling.
“MAXTEMP” or “MINTEMP” errors.
Layer shifts during high-speed moves.
Quick Fixes:
Inspect for kinks/pinch points.
Re-seat connectors (oxidized contacts cause 70% of issues).
Replace with shielded cable if coax isn’t available (temporary fix).
Alternatives When Coax Isn’t Necessary
Stepper Motor Wiring: Standard twisted-pair wires suffice (e.g., CAT5).
Thermistors: Silicone-coated PTFE wires work for most sub-300°C hotends.
Where to Buy Reliable Cables
Trusted Brands: Igus, Lapp Group, TE Connectivity.
Always verify cable specifications against your printer’s sensor requirements (consult OEM docs). Over-engineering with heavy coax adds unnecessary weight to moving parts.
