Play in the router

(Clinton C Caraway) #1

I purchased a Shapeoko 3 XXL locally.
While I was setting it up for the first time…
I noticed while changing the bit a lot of sloppiness in the router carriage.
Can someone please explain the steps to tighten up the router.
Thanks in advance and please remember I’ve owned this less than 24hrs so my knowledge of terminology is limited.

basic things first: Check that the rubber belts are tight (they should basically “snap” back but not be so tight that they don’t move at all).
Also check that the non-symmetric nuts that hold the bottom v-wheels of the carriage together are set so that the V-wheels are tight to the aluminum bar… the non-symmetry part will cause these wheels to move up or down as the nut rotates

The basic points of adjustment for a machine are:

It is also important to be sure that the collet is correctly tightened, the endmill fits correctly and doesn’t slip, and the router is mounted securely in the mount, and that the mount doesn’t shift. Note than endmill pullout can happen gradually, especially when profiling against tall walls.[4]

Also feeds and speeds may be a consideration: https://docs.carbide3d.com/support/#tooling-support and see https://www.youtube.com/watch?v=S9bceJxpqG0 for concepts on this and https://www.precisebits.com/tutorials/calibrating_feeds_n_speeds.htm for a testing technique and see the series #MaterialMonday: #MaterialMonday on YouTube

Beyond that it’s usually a matter of Calibration and Squaring the Machine c.f., http://docs.carbide3d.com/shapeoko-faq/how-to-calibrate-the-machine-for-belt-stretch/
