Final year project 2021 2 DOF motion simulator

hi everyone, I'm new in DIY motion simulator. right now I'm struggle to make motor to move.
I'm using Arduino Uno and motor monster shield as motor driver. im follow tutorial and wiring diagram but motor did not respond. for potential resister im using multiturn 10k. any suggestion or any solution for this problem? here im share some of my progress and everyone can give comment to improve my project.

thanks you for responding, i had tested MMs board and one of chipset was faulty. Now im think better to change BTS7960 cause very hard to find another seller for MM board. Any issue with BTS7960?

that good example. i just find one local product from cytron technologies DC Motor Driver (30Amp/5V-30V) MD30C. here some spec and which mode i need to go if i use this motor driver?

Which motor is good to be driven by MD30C?
As long as the motor:
- DC Brushed motor (Two terminals)
- Operating voltage from 5V to 30VDC
- Rated Current <= 30A
- Peak Current <= 80A
Features:
- Bi-directional control for 1 brushed DC motor, single-channel
- Motor Voltage: 5V to 30VDC - Maximum Output Current: 80A peak (1 second), 30A continuous
- Reverse polarity protection for Vmotor
- 3.3V and 5V logic level input,
compatible with:
- 5V Arduino boards such as Arduino UNO, Maker UNO, CT-UNO, Arduino Mega2650 - 3.3V Arduino board such as Arduino Zero
- Raspberry Pi boards which include 3B, 3B+, 3A+, Zero, Zero W, Zero WH
- Full NMOS H-Bridge for higher efficiency and no heat sink is required
- Regenerative Braking - Brakes the motor when PWM pin is low (logic low)
- Speed control PWM frequency up to 20KHz (Actual output frequency is the same as input frequency when external PWM is selected)
- Onboard PWM generator with switches and potentiometer for standalone operation
- Support both locked-antiphase and sign
-magnitude for external PWM operation.
Note: PWM is not "RC PWM" - Dimension: ~94mm x ~79mm

The potentiometers cannot be multiturn, they must be 300º

after a few day of break, i decide to not edit the smc3 coding. for now all my frame is done. waiting for BTS motor driver. i hope all is fine. for mutiturn potentiometer, im using ratio gear to make its rotate more than 360 degree for potentiometer. thanks to this thread for frame building. https://www.xsimulator.net/community/threads/from-atoz-2dof-arduino-wiper-playseat.4616/

now i see why. thanks for your comment. im buying 300 dgree potentiometer and not receive yet. it better using gear to connect to the shaft or just connect directly?

finally my project is done!!!
i faced heating problem at GRD wire arduino to motor driver when play around 10 minutes. so i change to from arduino male female connector to normal DC wire. problem solve.

for now im try to buy diy license for simtools and try to study how to plugin another game. im try to download game plugin from https://www.xsimulator.net/community/marketplace/categories/game-plugins.2/ but its show download not available. very sad.
