If you find your position in ground control or webcontrol doesn’t match where the sled actually is, you could theoretically jog the machine to the exact same “chain reset position” and then click Set Chain Lengths (Manual) (or whatever its called in ground control). The difficulty will be getting the sled to the exact “chain reset position” and it would be much, much easier and quicker to just reset the chains following this procedure: > [@How To: Manually Reset Chains, the Easy Way](https://forums.maslowcnc.com/t/how-to-manually-reset-chains-the-easy-way/9702): > > Every now and then you may find that you need to readjust the chains back to a known position. This could occur if you power/connection issue and the controller lost it’s position, had a chain skip, took apart something for some reason, etc… Fortunately, there’s a way to reset the chains without a lot of work. During calibration, after you set the sprockets vertical, you extend the chains out to reconnect to the sled. If your “Extend Chain Distance” is a multiple of a full revolution of the s… --- _[View the full topic](https://forums.maslowcnc.com/t/define-home-is-not-staying-centered-in-ground-control-0-0/11354)._
