Question about horizontal lines (gantry) (lemmy.world)

I had previously posted about some horizontal line issues I've been having, and I tried a lot of the suggestions I got; Unfortunately the issue persists.

I saw a video today, where someone mentioned that these connections that are basically responsible for raising and lowering the printer head should be somewhat loose, and not tight (as I had them).

Does anyone know if this is true? The video creator said that it is to allow for some 'forgiveness' between the two screws that drive the printer head up and down.

Thanks so much for all the pointers! 1, 3, 4 I will give them a try. I'll have to see how to disconnect the threaded rod from the motor so that I can roll it on a surface (I've done similar with arrows in the past).

For 2, the top is open, nothing was modified. This printer was bought used years ago (maybe 4-5 years ago) and used to print perfectly. It was not used for the last 3 or so, and has gone through several moves. When we unboxed it again, there were a few broken parts that we had to reprint (the upper stabilizers that go around the support rod and threaded rod, and the y axis motor mount in the back). So it's not inconceivable to think one or both of the rods could have been bent as well.

No problem, hope you find the cuse. Oh broken parts...I would inspect all mechanics and obviously clean and relube

I dont think you can remove threaded rod from your motor, but im not 100%. There are motors with motor coupler connecting to threaded rod (which can be simmilar issue if you dont leave a tiny gap between motor shaft and rod).

Thanks, I'll give it some proper TLC soon and clean/ lube everything.
