I have moved my ATC Hotswap code into a plugin, so I am releasing the VB m6 form for personal hobbie use.
this code is a hot swap for a 36 tool ATC. (arm, read-a-head, and screen set are not included), it is just a base example of the Meat of the Hot swap.

'This only show how to do the Hot-Swap code for the Tool Changer, and it moves a rotary caracell
'to the new position, the Arm and Draw bar code as well as the Status LED code has been removed.
'The logic for Tool desision tree for, Newtool vs. Oldtool and other error conditons have been removed.
'This example is for a 36 tool ATC.
