I am a newbe, do I have to set the x and y axis for every project or does my shapeoko4xxl remember it?
Yes, it remembers it — until one installs a new version of Carbide Motion which uses a new format for configuration files causing what was set to be discarded.
See:
https://carbide3d.com/hub/courses/running-shapeoko/movements-zeroing/
for what we have on that.
If you have a question about movement and zeroing not answered in that, let us know at support@carbide3d.com and we will look into it with you.
