I figured I would pull out the alignment pieces for the pulleys to see if I am way out of calibration on X and Y

Looks like I am!
This ever happen to other UMO owners? I wonder if a set screw got a tad loose? Seems easy enough to fix from the assembly guide tips

Should the number on the guide used to calibrate one axis be used the calibrate the next? I think so

In other news, the new pulley arrived!

There is no other purpose for the numbering than facilitating the alignment...

Okay, but i thought i saw in a video...maybe Neo had linked it in from his upgrade, that the same number should be used for each axis?

Doesn't matter, you just want them to be square.

And depending on where your set screws are, some are easier than others

And you get dutch course for free

Nou...

Yes! Now watch the video, they say (in TWO languages) to use the same marking!

I hate to admit this...I don't remember doing this when I built the printer!

No no no, you get it wrong

They just say "the same notch on both sticks" when you do a side (obviously, if you don't take the same notch it will be completely screwed )

Okay....perhaps i can make my printer happy again

How do you get those pulleys to line up if they are on opposite sides? Ahhh

All of mine are

...well...just tightened things back up, as best i could

We will see how that turned out
