Gantry assembly

I may be missing it somewhere but… I installed the two pieces of makerslide which make up the gantry and it says when assembling it, tighten the rear screws (which are in a slot and not a hole) and then back them off a turn. I’m not sure when to tighten them up. I’ve read through the instructions and scanned through the next several sections and not seeing anything about when to tighten them Any help is appreciated. Thx

You will want to tighten them up after you do the wiring, that way you have a little wiggle room for running the right Y axis stepper wire through. Before you try to run it, make sure you double check all your fasteners, and use loctite if you have it.

perfect thx
