I had the two bottom V Wheels break on the X-Axis. It was the second run on cutting 1/2" plywood. The first run worked fine; however, using the same file on the second piece of plywood, the Z-Axis dropped much more than it was supposed to, damaged the plywood, and broke the V-wheels. I am not sure what caused this, or how to fix.

I ordered some V Wheels from Inventables. They fit fine; however, they are narrower and are probably more susceptible to breakage.

I had problems w/ my Z-axis dropping too low until I used a small prybar to help tension the Z-axis belt.

Anyone know if the other vendors offer exact replacements?

Just came across this on eBay:

Looks like an exact replacement. :)

Note - I don't have any relationship to the vendor, never used them before, etc.

How's that different from the V-wheel from Inventables?

Not sure. It sounds like the ones from Inventables aren't an exact replacement. Was kind of thinking these ones might be.

Those V-wheels are identical to the ones I have, and mine are the same as the ones from Inventables. They match this technical drawing (PDF). Not sure what the exact dimensions are for the ones on the Shapeoko 3, but the few pictures I saw (including the one in this post) looked the same too.

If the Shapeoko 3 V-wheels are indeed wider (and I believe that), then nobody has an exact replacement...

I apologize for my previous post. I said that the V Wheels from Inventables are narrower than the Shapeoko 3; however, after measuring both, they are the same. My eyesight is not as good as it used to be. When I installed the V Wheels from Inventables, they appeared to me to be narrower.
