Voron 3D printer uses just one bearing per XRod... is that a smart choice? (1 reply)

Hi guys, just noticed on reddit about the release of a corexy 3d printer called voron and while looking at it it hit me that the XCarriage only uses one LM<#>UU (albeit something Mitsumi, not chinese) per XRod. Even Mitsumi or whatever brand LM<#>UUs have a certain amount of play in the bearings plastic tracks, which would translate to side to side rotation and possibly affect the print especially if the hotend is not straight in the center of the bearing (ex: dual hotend).

Have you seen the voron yet? What do you think (especially about my observed issue above)?
