@phaedrux All axes do what they should
I had probably used too inflexible cable, because after I had replaced the white by a remaining blue in the cable channel was then the red broken. So I had to make the complete cable chain "empty", and replaced all cables of this type😑 . But now it works.😀
Thanks for all your help.
Now comes the installation con extruder and honend .... there I will soon probably put another call for help in the forum ... but first I will try to understand the existing Gcode.
Thanks and see you soon.🙂
