Hello
thanks for the reply
the Jogdial plugs directly into any USB port on your Computer
and is controlled by a custom written software plugin that is supplied with it to make it run
in MACH 3
so it does not use your printer port..that is left to carry out the normal MACH 3 functions
the plugin was written in C++ and has several settings for for use .
Doumentation is supplied with the Dial.
