[FIXED] "burping" noise from Y-axis motor

Hi, I can't really come up with a good way to describe this other than the Y-axis belt making a "burping" noise and then the machine loses track of its position on the Y-axis. The video below does a better job of explaining. How do I fix this? The machine gets "lost" after two or three motions and is unusable...

Tow possible causes:
1. too low motor current
2. too tight Y belts

Hrm, the forum isn't letting me upload the video... I've emailed it to Juha, hopefully he can post it.

Thanks mawa, this was the problem!
There was too much mismatch in the tightness of the two Y-belts. The left one was very tight and the right one was very loose.

The forum restrictions for this and other similar stuff are off. I don't know why attaching a video does not work.
Maybe it is a BlueHost thing?
Anyway, I'm glad you got helped before I even saw your message.

It is the same file size restriction that
thereza ran into here.

I also had that problem when the acceleration and speed were too high for an axis.
