Hy-div268n-5a motored driver calibration

I am relatively new in dealing with LinuxCNC. 
I am modifying a Triac P.C cnc machine to use for welding. There are three 34hs, 3.1 Ampere bipolar stepper motor drivers which are used for themovement in the X, Y, and Z axes. I am using the HY-DIV268N-5A for driving the X and Y stepper motors. These stepper motor drivers are fitted with the TB6600 pulse generator. For the Z axis, we are using MicrostepDriver.
All axis are moving okay, however when the distance moved is not accurate with the one set in the code. I was told I need to calibrate the drivers but I'm not sure how to do it. In my LinuxCNC calibration menu I currently have the following values;
DIRSETUP 10000
DIRHOLD 10000
STEPLEN 5000 
​​​STEPSPACE 5000
STEP_SCALE 200
How should they be to give accurate movement as per the code
Regards

Hello Tommy,
I can access the calibration menu on the GUI. The issue is to what level do I adjust the scale so that it will correspond to the values in the g codes.
