I’ve finally resolved!!!! I was enabled min_software_endstop on my Marlin, after disable it (and sure, i move my machine in the correct position and reset home) all go fine!!!!
I’ve tried to cut my first part and the result is…… very bad 😀 😀
In your video (https://www.youtube.com/watch?v=c8_lJPNWDwA) did you have used Roughing and finishing togheter ?
I’ve cut my all part with only finishing but in the last step, machine have started to cut a lot of material (0.5 mm!!!)
I think a tutorial on how make great part will be aprecited to all 🙂
