RGB Controller Power Tap (Sienci AltMill)

A plug-and-play power tap that runs the ncSender RGB Controller straight from your Sienci AltMill's X-axis closed-loop motor supply — no separate power brick, and nothing to splice.

$24.99

Pre-order. Will be available in early October Expected October 2026. Your card is charged when you order.

DIY option

Prefer to build your own cable?

The tap terminates in a 2-pin, 3.81 mm-pitch pluggable terminal block — a Phoenix-style male plug and female socket with a screw-locking flange. If you'd rather make your own cable instead of buying the ready-made tap, this is the mating connector to use: 2-pin 3.81 mm pluggable terminal block set on Amazon.

  • 2 pin, 3.81 mm pitch
  • Phoenix-type male plug + female socket
  • Screw-locking flange
