How to select stepper motor for a Z-axis application with Ballscrew

[QUOTE="Vatech, post: 6544220, member: 680642"] [B]TL;DR Summary:[/B] it is needed to select stepper motor for a Z-axis application with Ballscrew. we suppose as knowing data that the z axis is verstical and the load is 6.6kg. I build a Z-axis (not the one displayed on image). The weight of the Buildplatform is 2.29kg and is going to be used on a MSLA printer, so the weight might get increased 1kg additionally, so 3.29kg. The problem is that when detached from the printed model from Fep film there is a resistive force, this needs tools and test to be calculated so this is unknown data for the time. That’s why i would like to be able to lift double the weight , meaning 6.6kg. The ball screw is a SFU1204 , meaning 4mm travel per full rotation. Friction [ATTACH type="full"]289517[/ATTACH] [B]I sourced experimental a stepper that has 1.8N holding torque, but how could i calculated the minimum Holding torque of the stepper motor needed to lift up the platform?[/B] [ATTACH type="full" width="638px"]289516[/ATTACH] [/QUOTE]
