Voron Legacy Carbon Fiber Shaft Set

$59.99
Shipping calculated at checkout.

The complete shaft set for a Voron Legacy, in carbon fiber: ten 8mm x 320mm linear shafts, the exact cut list the official Legacy configurator gives for the 230mm spec. Two for X, four for the quad-shaft Y, four for Z. One bundle, nothing to cut.

What's in the set

  • 10x 8mm carbon fiber linear shafts, 320mm long. Solid pultruded rod, matte black, 24g each. A steel 8x320 shaft is about 125g; this whole set weighs less than two of them.

Why carbon fiber on a Legacy

  • The two X shafts ride along with the gantry, so that is where the weight comes off. The Y and Z shafts are stationary; there, carbon fiber mostly means they never rust and never need oil.
  • Same idea as the Baby Legacy Motion Kit, at full Legacy scale.

Not included

  • Bushings. The Legacy BOM calls for ten LM8LUU-size (8x15x45mm) linear bearings. On carbon fiber, use the polymer version of that size (igus drylin style); these shafts are test-fit in an igus drylin bushing, see the photos. Never run steel-ball linear bearings on carbon fiber; the balls chew the resin.
  • Belts, pulleys, leadscrews, printed parts and the frame. The Voron Legacy Frame Kit is listed separately.

Specifications

  • Printer/project: Voron Legacy, 230mm spec (2x X, 4x Y, 4x Z, all 320mm per the official configurator).
  • Shafts: 10x 8mm x 320mm, solid pultruded carbon fiber, matte black.
  • Diameter: 8.00mm measured (0.315 in on a dial caliper).
  • Weight: 24g per shaft, about 240g per set.
  • Bearing fit: polymer bushings only (LM8LUU size).

Gotchas

  • If you cut or sand carbon fiber, use ventilation, a respirator and wet methods to control the dust.

Shipping:

US Shipping is via UPS or USPS. The way it is set up shows the least expensive options for standard, priority and express shipping. I can not take special requests for specific carriers at this time.

International shipping is mostly UPS, as I utilize Zonos/UPS integration to tally extremely accurate import and shipping costs.

I require a telephone and email with international orders and you must make yourself available to the carrier or your customs, should they require more information. If you are unreachable and the package is discarded or returned, I will not be responsible for returning your shipping cost.

If there is a problem with an international order, it is my choice to refund part or all of the order, or send a replacement.

Addresses are verified through Shopify, but the customer is still responsible for inputting their address in the correct format. Any returns or lost shipments, due to incorrectly addressed packages, are the responsibility of the customer.
