Working on assembling my Carve King since it arrived today and I've noticed a few things that are confusing.
1. The bearings were impossible to push into the Delrin V Wheel's by hand and I ended up using a C-clamp on the end of my table to push them in. Might need 1 replacement roller shipped as it was so tight that it deformed the plastic and now it doesn't roll smoothly.
2. Holes in the plates didn't seem to be drilled out completely. Didn't think it was a problem until I installed the Y motor and the shaft coupler's set screw hits it and the shaft won't rotate past it. See photo attached.
3. Assembly Instructions V1.06 Page 5 Paragraph 2 says to slide the coupler ALL the way down onto the shaft until it stops, but mine slid ALL the way down until it was touching the motor. In the photos on Page 6, it looks as though there is a red piece of plastic that stops the shaft midway, however on my couplers the shaft goes all the way through. This caused problems (see #2 above).
Any input would be greatly appreciated. I'm scratching my head and thinking of work-arounds.

1. I will try to explain this part though I think you have completed it already. What I did was take the z motor plate (or any plate that the wheels would generally install to, and used the plate as a "backer". So, bolt through the plate, on the other side of the plate - washer over bolt, delrin, bearing, bearing washer, bearing, washer and then nylock nut. Keeping the bearing and delrin wheel aligned, slowly torque the nylock nut to compress the bearings into the delrin wheel. This is a trick I have been using from my 3d printer builds.
2. The holes weren't drilled so much as they were cnc cut (laser or water I believe). It is very easy to get a drill bit in there and just bore it out to its correct diameter and you will be good to go.
3. If you bore your holes properly all you need to do is install the coupler AFTER the motor is attached to the plate. This will allow you to "reference" the coupler location. Like my 3d printer builds I generally push the coupler down to the lowest point I can while still being able to access the grub screws.
When I assembled mine I noticed the issue with boring out the plate holes so I did all those first. And then I did the delrin wheel assembly. For me everything after that went smoothly.

Thanks for the rapid response. I didn't drill out the holes but have been able to assemble with the little notch in there. Hopefully this won't cause heartache downstream. Glad everything is going smoothly with your build!

Check my thread with a link to my build pics.
I assembled the x-axis drag-chain "guide" (aluminum piece) upside down to work better with the drag chain mount that I designed/printed.
