Run touch screen calibration with Pi version?

Having very poor touch calibration issues with my VERY cheap HDMI LCD that connects via GPIO pins.

At the bottom of their guide they say how to install the utility, but I'm not sure how I can launch it? Any tips? Seems I'll need to launch it via Putty? But I'm not sure how....

Here is the documentation: https://github.com/UCTRONICS/UCTRONICS_LCD35_HDMI_RPI

Maybe I can add/modify a button to launch the calibration tool? Any help would be appriciated!

Here's the screen: https://www.amazon.com/gp/product/B076M399XX/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1

    You can start graphic application from ssh shell. Just set DISPLAY like
    export DISPLAY=:0
    and then call the executable. I think it is named xinput... use tab key for autocomplete if you do not name of the installed binary.

    This pointed me in the right direction!

    DISPLAY=:0 xinput_calibrator

    launched the calibrator I installed!

    Did you use the sd card they provided you? Im trying to launch repetier from raspbian with no luck.
    I also flashes another sd card with repetier server but the screen doesnt work and in the process of installing drivers I lose internet connection. I made an xml file for wifi but nothing
