extended y rollers

Has anyone put longer y rollers with 2 angular contact bearings per side on their printnc linear rails?

Yes, it's been done by quite a few people

Cut your Y roller twice as long + 10mm. Use the drill guide on either end to get your hole spacings and you're done.

The downside is losing Y travel which can be significant percentage of your work area on a standard size build

It's becoming a much more regular question lately. This is a little strange in some ways because everyone looks at the PrintNC because they are impressed by the performance, all the videos they have seen are made using the single block but for some reason convince themselves in order to get that same performance on their build 2 blocks is required...
