To ensure you have a reliable connection to your HeaterCore, you should follow the best practices outlined in this document.
- To avoid putting strain on the HeaterCore cables when the printer is in motion, leave some slack in the wires. Repeated pulling on the HeaterCore cables may result in damage to the HeaterCore.
- Do not have tight bends in the wires immediately before the connectors.
Tight bends near the Molex connectors can damage the crimps.
Avoid messy or tangled wires with lots of sharp bends.
Avoid sharp bends in close proximity to the connectors
- Use the stock Molex connectors unless otherwise specified in an official E3D Upgrade Guide:
As using butt splices is specified in the upgrade guide, Revo CR is exempt from this point
- If you experience temperature fluctuations, check your crimps at the connector to ensure they have not opened up. It's a subtle difference but it can lead to an intermittent connection so it needs to be correct.
If they have opened up, you can attempt to close them. A pair of tweezers or a very small flathead screwdriver can work.
- If there are tight bends in your wiring, especially near the connectors, consider using our printable connector clips. These clips help to prevent movement at the joints between the HeaterCore and Extension cables, which can lead to sudden temperature fluctuations. You will need some cable ties to secure them.
