Y-axis wobble

I have been messing with this for a while, but can't seem to figure it out: every time I go to print something (I've currently been trying to print the logo while troubleshooting) the Y-axis shifts out of place from layer to layer. After searching the FAQ's on this, I checked both the X- and Y- axes' belts, to see if that was the problem. The answer: inconclusive. If someone could help, perhaps either defining what exactly a loose pulley is, or how to fix one, that would be great. Thank you.

Yes, I support cream cheese llama anarchists. Who doesn't want free roaming cream cheese or llamas?

Re: Y-axis wobble

There's unfortunately no good definition for belt tension, or pulley-whatever for that matter.

What power mode are you running the steppers with?

Re: Y-axis wobble

Worst case is a bad y-motor. I'm going to skip loose belt or low-power mode as those would be caught in FAQ. I've had something I call "stair slip" once when I went crazy with a newly designed y-tensioner. I built my kit to spec but slight variances in 3D printed parts and my own sloppiness meant stock y-belt mount and y-motor rubbed badly on pulley and gear. Turned out with my tensioner exacerbated poor alignment and loose y-belt so I seated belt fully, adjusted y-motor mount right until the belt sat square in the center of its gear while at end-stop. Fixed the issue for me.

Thomas Sanladerer of Youtube fame states Bass E is a good place to set your belt tension and that is what I follow.

Also, it would be good to show results of bad print as blind diagnosis is more soothsaying than analysis.
Hope this helps.
