Something like this has a chance to be released soon as an upgrade.

http://www.shapeoko.com/forum/viewtopic ... =10#p55834

Ed was looking into that all the way past September, and I was lucky to get onto beta testing that plate.

Can't tell for sure what is going to be the latest iteration of this upgrade, but there is one coming.

Isn’t a variation of that plate a standard part of the XL/XXL upgrade?

ISTR that Carbide 3D has stated that some replacement / upgrade parts will be available on the shop when they have the chance.

Again for me this is not and upgrade for a S3. I am looking to upgrade my S2.

I might be a little dense, but how exactly would this upgrade it?

I too would like to upgrade my z axis. but I can't picture how this works.

I can picture how it works, but I disagree that it's an upgrade. :)

I do not have a S3 so can not say if I think it would be an upgrade for that. but there looks to be more surface area with the OX wheels than the standard V wheels in the linear actuator. I have seen at least one that has changed out to this set up and there is way less play in the Z. I have not found anything yet on ebay in this price range as of Yet. I have not pulled the gun on this purchase yet. But I still have not ruled it out.

How do you figure? The V-slot running surface is under 2.5 mm wide on either side (an 1.8 mm thick profile wall sloped at 45 degrees gives just over 2.5 mm, but there's always a radius at any edge, so 2.5 mm is being generous). The Shapeoko 3 V-wheel has a groove about 2.8 mm either side, and almost all of it engages the profile (not all of it because the profile edge rounding is a little wider than the groove in the middle of the V-wheel). If anything, the Shapeoko 3 wheel has a little more contact area than the V-slot wheel, not less. Of course, a 10-15% difference in contact surface area is not the entire story. With a much larger distance between the wheels, and shorter spacers, the Shapeoko 3 wheels are stressed less under the same sideways load on the spindle.

Sorry I realize this is an older thread. Its an upgrade because the z-axis plate is now u-shaped which adds more rigidity. The initial kits were just flat stock and its now being learned theyre not rigid enough. Its actually impressive how simple of a manufacturing fix this was.
