Well there is still allot i dont know, when i say 120 i meant that was the setting i placed in cura, i have not touched the acceleration settings, so those things are the defualt.
I would say the speed was like your last video example, but it did not feel good. Right now the speed is about the one of your first video. Do i have to worry about if i go to fast the hardware will break? Or is it more i can go as fast i want so long build quality is good?
