HPV4 V-Slot Linear model 400-500mm 3401S Stepper motor T8*8 Lead Screw 2/4/12/14mm Z-axis router Reprap 3D printer sapre parts Review

Let’s break down the components you’ve mentioned for Reprap 3D printer spare parts:

1. HPV4 V-Slot Linear Model (400-500mm):

   • This linear model is designed for precise movement along the Z-axis in 3D printers.
   • It comes in various effective travel lengths: 400mm, 450mm, and 500mm.
   • The guide width or diameter options include T8-2mm, T8-4mm, T8-8mm, T8-12mm, and T8-14mm.
   • You can find this kit on Aliexpress for $26.99.

2. Stepper Motor (3401S):

   • The 3401S stepper motor is likely a NEMA17 motor.
   • Unfortunately, I couldn’t find specific details about the 3401S variant, but NEMA17 motors are commonly used in 3D printers.
   • These motors provide precise control for moving the printer’s axes.

3. Lead Screw (T8*8):

   • The T8*8 lead screw is part of the Z-axis mechanism.
   • The “T8” refers to the thread pitch (8mm per revolution), and the “*8” indicates the lead (8mm of linear travel per revolution).
   • Lead screws are essential for translating rotational motion from the stepper motor into linear movement.
