Just got my first 3d printer today - the lulzbot taz 6
I followed the set up instructions but got stuck on step 7B where they asked me to let go of my tool head and let it self level.
As you can see, my printer slants to one side and does not centralise when I try to do so.
I then tried to centralise it myself by manually adjusting it and slowly tightening the m3 screw
No matter how much I tightened (And i did it really slowly, bit by bit to see if it helps), the tool head would be loose.
After a while, and without any indication (it was still loose), it got over tightened and it broke as you can see below.
