But these advantages are most useful in printers that use cable chains. PTFE or Heluflon wires are a premium option as they have a thinner insulation and a lower friction coefficient, which increases bending capabilities and decreases wear. Check your cable loom before installing the chains. It is less prone to snagging on other wires or the walls inside the cable chain. Silicone insulation withstands heat and is more flexible which is good in high movement applications. Silicone wiring has been specified because it has a high strand count which means it has higher fatigue life. When assembling Microfit connectors, the male pins are inserted into the female housings and the female pins are inserted into the male housings.įor larger wires, such as heater cartridge wiring, heatshrink tubing is helpful. The thermistor can use a 2pin Microfit connector. Use a 3pin MLX connector (see the official sourcing guide) to allow your bed to be removable without disconnecting from the SSR directly. Adding Molex connectors to all stepper motors is useful. JST connectors are not available as mid-wire connectors so they must be mixed. The recommended MicroFit 3.0 connectors are specified for up to 5A and should be used for all connections to the stepper motors, hotend and limit switches The JST connectors are used for connections to the MCU board(s).
