Hi @JoseRoberto thanks for that picture.
Farmbot axis movement maximum speeds are many times slower than a typical 3d-printer !
This fact is due to the hardware design of the robot; gantry mass, axis rail and cable duct frictions, motor size, etc.
I haven’t been able to find a general number for expected maximum axis speeds or the maximum step pulse rate per motor out of the Farmduino and the stepper drivers used.
There are many Forum Topics and posts about setting reliable Axis motor speeds, e.g.
Also check the on-line Documentation, e.g.
Might be worth setting your motor parameter values to Defaults and then changing one parameter at a time ( in small differences ) to find the Maximum speeds for your machine.
