so i deletet the first Block of the Code, sliced it again, and print it with SD Card directly from the Duet.
The Speed is still MUCH to fast.
Printspeed is 55mm/s in Slicer - and with 100% Speed, is about 125mm/S estimated.
I Reduced the speed to 70% - now the Web Panel shows me 20mm/s, but i think its about 50 or 60mm/s
The proportions are ok... Test Cube , and its 2x2x2...
I am so coonfused
