I can see on the left of the carrier too much space between the carrier itself and the x-end stop. If A3 assumes that the x-origin point is for example 2cm at left of the bed it considers that the real start point is that… then you have to add a gap in x to correct it. Later I’ll send you some pics
I don’t use Cura for Afinibot A3, but Repetier-host and Slic3r. This solution permits to set the offset before the nozzle reaches the bed. I presume that in Cura You can try to adjust as need the value where i mark with a red circle. I don’t know if you have to use negative values… (it could be).
Measure the distance between the nozzle when in x-home and the left corner of the bed. Put the value in the first field (probably negative).
