I mounted the top plate to my CNC, and routed a slot for the perimeter of the angular contact bearings, and filled it with epoxy. Tomorrow I'll pocket out the center, and pour a little more epoxy in there. When finished, the angular contact bearings will have no contact with wood. I don't want oil soaking into any wood. I could have done it in one step, but I would have used a lot more epoxy, and 90% would be routed away.

I'm in no hurry, as I'm still fine tuning the design to make sure it's right. I added a cover for the Z axis belt drives, but needed to change it when I added the Y axis E-Chain. Now I need to model a home switch housing, and throw it on there. I'll probably lower the upper limit switch, and put the home switch above it. A single ramp will be mounted to the Z carriage to activate the limits.

On top of the cover I'm going to have a small box between all the E-Chain to tie the limits together, and any other electrical connections I might need.

As for the E-Chain, I need to call Igus to get some pricing. I sent an email to a chinese manufacturer on Ebay who sells a knockoff (looks like they're using images from Igus ) to see if he has what I need, as it needs to have a specific bend radius to work right. I'd prefer the Igus, but if I can get the 2 Z axis chains for $25 from China, I may have to go that route. But I'd be willing to pay about $60-$75 for real Igus.

I've also fixed the AutoCAD model to match what I'm cutting.
