Before adjusting software, ensure the physical controller is functioning:
: A triggered limit switch can sometimes be misreported as a hardware failure. Use a metal object (like a screwdriver) near the axis limit switches to see if the input signal changes in the software.
: Many NC Studio versions (like v5.4.53) only support 32-bit Windows systems. Attempting to run them on 64-bit systems without specific "repacked" drivers often triggers failure.
