Hay everyone so got a Ender 6 modded out with a duet wifi 2 and when I home the printer it shows that the x axis is 215.0 out and not zero got the stock end stops Y shows zero and can't find where to change it any help would be great thanks.
@Chris-S M574 defines whether you're homing to the low or high end.
It sounds like you're homing to the high end, so the value when the stop triggers should be max travel as set by M208
You'd need to post your config.g so that it can be examined properly.
