I found the v-slot system recently and watched a lot of the videos posted on youtube. The belt and pinion system looked really slick and it got me wondering if it would work for the vertical system of a Delta printer. Is the weight of the drive motor too much to maintain accuracy? Most machines use a pretty small shuttle attached to a belt or line but the pinion system looks more positive to me if it can maintain position with the added. weight. I don't know much about the subject but have been gathering all the information I can. Thanks for any input.
