1. PoKeys plugin for Mach3 is not installed: the PoKeys plugin for Mach3 is selected to be installed by default to C:\Mach3\Plugins folder. If you just run the PoKeys setup, the PoKeys plugin will be copied to that folder.
2. kbd48CNC not working: there is a manual available for kbd48CNC keyboard on the kbd48CNC product homepage (https://www.poscope.com/index.php?route=product/product/download&download_id=50&product_id=53
). The manual guides you through the installation of the keyboard (it needs to be registered in the PoKeys software first, as you did). The essential step to making it work is to either manually configure the functions of each key or simply load the configuration file for the plugin, as described in the manual.
