Hey Ken,

this is a frequently asked question. We have a search function here.

Onefinity provides a help file which deals with many kinds of blocking of an axis:

- [Troubleshooting: Rail is getting hung, stuck, or out of alignment](https://forum.onefinitycnc.com/t/troubleshooting-rail-is-getting-hung-stuck-or-out-of-alignment/10826)

I would check all points one by one to see why your carriage does not move anymore in the middle of the axis.

There are three causes that are **not** mentioned in the document above:

1. Should your machine not be properly [rectangular (“squared”)](https://forum.onefinitycnc.com/t/what-do-i-do-first/18349/6), the Y movement can block.

2. And the second possible cause not mentioned in the document above is: [This mysterious issue](https://forum.onefinitycnc.com/t/help-losing-home-during-carves/7022/70) some time ago.

3. [Electromagnetic interference (EMI)](https://en.wikipedia.org/wiki/Electromagnetic_interference), as e.g. [mentioned here](https://forum.onefinitycnc.com/t/weird-bahavior-between-controller-and-110-volt-2-2-kw-huanyang-spindle/15650/10).
