Wobble in x axis lines.

Post by Knotty_Dawg » Fri Dec 25, 2015 2:03 am

Making some cribbage boards tonight and fing that I have a wobble along the x axis when routing straight lines. Happens at the same place in parallel lines.

Went over the v track bearings, all seem tight.
Picture sort of shows it, just barely noticeable deviation.
Reduced feed 50%and the same wobble occurs.

Could it be a slightly out of wack v bearing?

Any ideas?

Check the repeat distance of the wobble. If it is the same as the perimeter of the wheels that means that one (or more) of your X wheels have ball bearings that they are wobbly or not correctly fitted in the wheels.

Insightful diagnosis!

Not a problem I can recall having come up, and am faintly surprised at that.

I think you may be on to something there.
Also found evidence that one of the belt bearings is making contact with the rail.

It was a bad v-wheel on the X axis.
One side of the v alternates thick to thin and is shifting the Z axis assembly.

Now to order a few spares.
Are the ones from Inventables the same? https://www.inventables.com/technologie ... -wheel-kit
Or is there another source(s)?
