Hey Rob,

you are right. I don’t remember why I did not give the hint to use G53 prepended. This post is very old.

By the way, see also [G53 bug](https://forum.onefinitycnc.com/t/g53-behaviour-on-buildbotics-derived-onefinity-controller/26174).

See also [Aiph5u’s ‘tool-change’ routine](https://forum.onefinitycnc.com/t/tool-changes-and-z-height/7715/29); I read the other day that someone prefers a position more in the middle of X travel for manual tool change, can be modified to suit your needs.
