So far, I’ve been running my LR4 with the Z stubs disconnected (no bolt through, seated by gravity alone). I understand the docs for this are still a WIP.
This seems to have the bonus side effect of protecting my shaft couplers from stretching out/“springing” if I were to drive the router/gantry into the table with too much force, or inadvertently, as the stubs will simply unseat themselves.
Am I going to gain any benefits by putting in the connector bolts, or are other people doing this too?
I definitely had accidentally driven my lr2 into the table and stretched out the couplers, so this seems beneficial so far.
I think @vicious1 mentioned somewhere that he wasn’t using his either, not 100% on it though. I have them very loose as well. If you tighten them, Z is going to bind. That I know at least.
Another benefit seems to be when lifting the LR4 by the gantry to store it, you’re not lifting it by the couplers and stretching them out. It does put quite a bit of force on the end stop switches though, so might have to make a “Liftin’ Clip.” Yeehaww!
I’m going to sheepishly ask: How can you run the z, have it work, but not connected? Are you talking about not cranking down the grub to the motor shaft or to the lead screw?
A.k.a. the two-part thingy that people are happy their 3D printer makes correctly. There’s a hole, through which you can connect them, if you’re feeling bold, which I am not.
