Nema23 --> Makerbase --> setup

Hi to all.
I need to setup 3 stepper motors on the makerbase board. I didnt use this board before but i run some basic setup and i uploaded Marlin 2.1.2 on to the board.
I also set A4988 stepper driver on the board.

When i run pronterface i can see successful connection on com 5 and i can also see that marlin 2.1.2. is installed.

Basically everything is working but now i need to set maximum speed of the motor and i dont know where can i edit this data.
For now, when i try to move motor in any direction ( using pronteface ) the shaft is not moving but you can easy hear buzzing of the motor when i try to move it.

So, it looks i need to setup steps, but i dont know where or how. I have added all 3 jumpers under A4988 driver.
Can this motor setup be found somewhere under Marlin directory or under pronterface ?

Motor type that i use:
[www.sys-motor.com]

Best regards !

stepper motors are rated current/phase 3.0A but A4988 stepper driver is only rated for approximately 1 A per phase without a heat sink or forced air flow (it is rated for 2 A per coil with sufficient additional cooling).

This is not a good match, best case it stepper motors will preform way under the rated torque. worst case they may not turn at all

Micro stepping is set with the 3 jumpers. all 3 is setting 1/16th micro stepping (jumper on is HIGH)





Everything else is in Configuration.h

/**
 * Default Axis Steps Per Unit (linear=steps/mm, rotational=steps/°)
 * Override with M92
 *                                      X, Y, Z [, I [, J [, K...]]], E0 [, E1[, E2...]]
 */
#define DEFAULT_AXIS_STEPS_PER_UNIT   { 80, 80, 400, 500 }

/**
 * Default Max Feed Rate (linear=mm/s, rotational=°/s)
 * Override with M203
 *                                      X, Y, Z [, I [, J [, K...]]], E0 [, E1[, E2...]]
 */
#define DEFAULT_MAX_FEEDRATE          { 300, 300, 5, 25 }

Thank you very much for fast reply.
I was thinking almost the same regarding the drivers but this was cheap solution for some basic setup and like i wrote, this is the first time i use this board.
The A498 driver has on chip cooler and cooler is totally cold.
When i run test on pronterface the motor starts and the whole motor is "shaking" but shaft is still.
Anyhow, i will try to change the config setup.
-----------
I am following this example
[www.youtube.com]
to test the board over Arduino IDE but can you tell me the order and pinout of X axis of the makerbase board ?
I google but i didnt, find any useful info...
---------
Btw. I think i have two microstep drivers (9-40V) in garage so i can use those.
----------
When we talk about that, is it possible to hook up 3 or more steppers ( maybe servo in the future ), each at least 100W to makerbase GEN_L V2.1 ?
I am planning to make one basic 3 axis robotic hand.

Often shaking is miss wired stepper motors.

the printer has a 4 pin connector, pins 1 and 2 are the first coil, pins 3 and 4 are the second coil, so you should have

1 black
2 green
3 red
4 blue
