So in this step, it says the snug the Z stubs using the two screws, which I did , then it says to leave out the cross tensioner screws for now which I did. Looking through the instructions, I don’t see anywhere where you actually tell us to put the cross tension or screws in or did I miss it ?
In my beta program builds, I seated the nuts in the Z stubs, then didn’t put the cross screw in until I mounted the gantry to the two YZ plates (Late in assembly).
It’s pretty convenient to be able to install and remove the cross screw if you have to fiddle with the machine.
The other trick I found useful is I made some blocks out of scrap wood that supported the X gantry and a couple of different heights.
I did all my assembly solo and found it more convenient to be able to set the gantry on some assembly aids.

Before updating to independent Z drivers and an IR sensor on my home-made Prusa i3 clone, I would use two soup (or tomato paste) cans to set the X axis parallel to the build plate. They’re mass produced, so are acceptably close to the same size for the precision I was chasing at that point.

So, I have never put mine in on an actual build it is not actually needed. I am slowly working on updating the instructions now and I will add the cross clamp screw part soon.
When you put it in you need to make sure your Leadscrew is not moving. Meaning it is directly above the Z coupler. There is a measurement test and a movement test. the top of the leadscrew should stay the same distance from the outside face of the YZ plate when the gantry is all the way up, vs all the way down. Much easier on a LR4 than an LR3

Ryan did you get my message other day re skr screen on clamp
No I didn’t, if you emailed me I am a bit behind. I am currently averaging 437 emails a day. One bad day and I have a hard time catching up.
Please start a new thread and we can discuss it there.

says the guy not having to answer all 437 of those emails 
yeah, I was trying to fix a notification issue on my phone. It buzzes all night with every new email, and never used to. Found the setting and in android it gives you a daily average count…yesterday was 437 for gmail. That is nuts considering for about 10 hours a day I get them before it updates my phone, so who know how many I actually sort through.

With an 8 hour working day that’s only a little bit above 20 mails per hour, plus packing boxes. Easy. 
You are right… Math isn’t your strong suit

Yeah, but if you take the real number of ~55 per hour it gets a bit depressing.
