Hi i recently bougth the A40640 laser module, and the new version is arrived today. I’ve noticed a second 2 pins connector near the normal 4 pin connector. What this connector has been used for? @JackWong can you explain please? cause i found no infos neither in Neje wiki nor in Neje shop description.
Additional power interface, connected to 12V power supply, reduces the pressure of single-circuit power supply, for special requirements, customers use it on other machines, the power supply is insufficient, can provide 12V power supply separately
