Hey Adam,

you’ve been hard at work making videos again!

I like that you describe the increase of spindle deflection when someone should slide the spinde too much downwards in the mount. However what you describe is the design error that let the Onefinity Z assembly differ from usual ones, [that allow for the spindle mount to protrude downward much more, even down beyond the lower end of the Z rails](https://forum.onefinitycnc.com/t/wasteboard-too-short/22863/11). That is what is unfortunately impossible with the Onefinity Z assembly, and forces users to slide their spindle or router much lower into the mount, thereby increasing deflection. That is why, like Tom @TMToronto, replacing the complete Z assembly is at the top of my list. I’ll see if I can make the parts with the old Z assembly, Tom managed to do it. Thanks Tom 🙂
