С 2013 года (даты сообщений) уже прошло прилично времени. В вашем случае, я бы спросил напрямую у автора PoKeys то, что желаю знать наверняка. Если спрашивать не хотите, то скачайте хотя бы плагин для 
Mach4, там в архиве есть файл 
Changelog.txt. В нём указано, что еще в ранней версии плагина 
7.6.1.2522 добавлена поддержка компенсации люфта (backlash).
