When you realize your printer has been running for months broken lol

Call me blind, but I’m not getting it. : /

@Xenomorpheus I’m guessing that it’s the bearing that’s moving back and forth on the linear rail.

I dont get it

Oh, ok, I see it now . . . damn, that would really throw off his alignment. He’d be lucky if his prints turn out right for so long.

I actually don’t think it’d throw the alignment off that badly if that were the case.

@Justin_Nesselrotte

If it gets snagged, it would throw off everything by several thousandths of an inch. He kept it lubed well enough I suppose that it didn’t happen.

I’m presuming based on the way that it’s moving that the motor never skips steps or anything.

So, those IGUS bushings are meant to be press-fit into a housing so that they make it down to the specified diameter. If this is moving back and forth in that holder, it means that the IGUS bearing will also be significantly larger ID than the rod it’s meant to be riding on, resulting in sloppier prints (though gravity helps somewhat preload here)

Yeah i had it running like that since installing my cable chains. I realized the part was broken when i was installing it and i planned to print a replacement once i put it all together but then i forgot about it and i kept wondering why my printer was making such aweful noises when moving accross the X axis. Well i found my issue lol. In that video im actually printing the replacement. Already inatalled it and there are no signs of that aweful noise my printer sounds so smooth now :slight_smile:

@Mazlan_Abd_Majid GTFO of here with your spam! You’ve been reported!

@Kevin_Danger_Powers tag me, or justin, gina, and we’ll take care of it pretty quick. I got rid of it.

Since your replacing parts, I have to agree that the cable arm is too far away from the print head and causing misalignment issues. It should be mounted as close to, and above the rails to prevent leverage misalignment of the print head.

14

So youre saying the arm is sticking to far out from the back of the print head?

15

Thats a stock part from the cable chain upgrade for the Prusa thou. I guess ill try shortening the arm and see if that causes any issues or improvements :slight_smile:
