Coreless Servo

A coreless pen-lift servo upgrade is available for most AxiDraw V3 and SE series pen plotters. It offers a greater lifting strength and is significantly quieter than the standard (Tower Pro SG-90) pen-lift servo motor.

Purchase the upgrade for a compatible AxiDraw

• If your AxiDraw has a silver-colored pen-lift servo mount, purchase the full upgrade kit.

Prior to purchase, check the information on that page to confirm compatibility with your AxiDraw.

• If your AxiDraw has a black-colored pen-lift servo mount, you can purchase just the "replacement servo", with the full lift arm.

Again; prior to purchase, check the information on that page to confirm compatibility with your AxiDraw.

Replacement coreless pen-lift servo

• If your AxiDraw already has the coreless pen-lift servo, you can purchase a spare or replacement unit here, either with or without the full lift arm.

Upgrade instructions

• Installation instructions are available here (7 MB PDF file).

This document includes the full installation instructions for the upgrade, as well as an end section with instructions for replacing the rolling wheel on the lift arm and calibrating the lift arm position.
