Mks dcl 32 parametrj

Recently I bought a mks dlc 32 I also took 2 servo 42c nema 17.
I set the values ​​of the speed, step and acceleration parameters and I make the controller read them to have an idea of ​​how long the processes last approximately…
But it doesn’t work there is a huge difference, sometimes even 3 hours and more.. Why? I’m sure I’m doing something wrong

Maybe not. If it is an image, long times are typical. Otherwise, you did not give us enough information to be of any assistance.
