Spindle Overview

From ShapeOko
Jump to: navigation, search

The typical choice for a tool (the industry term for this is spindle) is a trim router (a Dewalt DWP611 is suggested).

Rotary spindles are the most frequent tool choices, but there are a number of other options.

Pen / Plotter Mounts

Mounting a pen is something of a rite of passage.

Rotary Spindle Options

The Dewalt DWP611 and the Makita RT0701 are the main choices for spindles for the Shapeoko 3 (they also work well on suitably upgraded Shapeoko 1/2s).

Notable differences:

  • Dewalt has finer-grained speed control, Makita lower and higher range of possible speeds (the lower speeds are especially useful on plastics and wood)
  • Dewalt has multiple precision collet options (standard ones as well as the ER-style collets from Precise Bits), Makita has a single source for precision collets (albeit in a variety of sizes)
  • Dewalt has lights, the Makita does not[5]
  • Dewalt has a plastic button on the Body, which limits Z plane positioning inside the mount, Makita has a more Robust Tool changing mechanism, with a cylinder push lock below the shaft, which will allow more mounting options in the Z plane[6]
  • Makita bearings easier to change
  • Makita brush life longer and replacements less expensive and easier to change

Note that spindles may be upgraded w/ better collets. Some are merely replacements for the standard collets in different sizes, while at least one manufacturer offers specialized systems which allow one to use ER style collets.[7] These are more convenient and easier to change (esp. if one buys a matching nut for each collet) and afford a greater clamping tolerance (e.g., a 1/4" collet can hold a 6mm endmill[8]).

Engraving Tool

Similar to a rotary spindle is a high-speed engraving tool:

Laser Cutter

Mounting a laser for engraving and cutting is a popular upgrade. While it does have a number of safety implications, it affords options which aren't feasible otherwise.
