Hi,
In his post joeaverage mantioned BoB - what is BoB?
A BoB stands for a Breakout Board.
A BoB is required for the db25 parallel port plug to interface with real world circuits, it has buffers and amplifiers etc
but it does not do anything smart.
Your external motion controller may or may not have a BoB in addition to the controller. I would guess that the controller
has the buffer functions built in and therefore you will not have a separate BoB.
