Here we go again . . . MK4

Hi Routercnc I've just been going back through one or two of your videos when the dire internet here allows, and I'm curious about one of the things shown in episode 23, where you square up the gantry.It looks like you're achieving this by having independent limit/homing switches on each of the horizontal axis ballscrews, but doesn't this leave the whole assembly under quite a bit of tension?? or do you home it with the screws slackened off a tad then tighten?And does it mean you need to have separate drives from the control software for each of the steppers?
Although it's not assembled yet I'm trying to figure out how I will square up the gantry on my little machine, bearing in mind that my gantry is quite short (~600mm) and a very rigid bit of box section.
Thanks, Trevor
