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

Those are timings, you need to set the scale depending on the motion type, microstepping, gear ratio, etc.
For that use the "calibration" menu found on most GUI's, change the "scale".

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.

This depends on the motor steps-per-rev, the microstepping ratio and the ballscrew pitch.

To take an example of a 200 steps motor at 4 x microstepping and a 2.5mm pitch ballscrew:

200 x 4 = 800 steps per rev
one rev = 2.5 mm
SCALE = 800 / 2.5 = 320 steps per mm. 

For an imperial machine you would get a different value, 8128 steps / inch.
 

Sorry, i missed this.
