Re: [CAD_CAM_EDM_DRO] Re: USB ports ?

Wasn't Art Fenerty working on a system like this for Mach2? He referred to it as a "cube" or something like that? Basically a remote pulse generator. However, I understood it was to work from the parallel port. Maybe he already released it and I'm unaware of it.

Hi Dave

Not wanting to appear to be rude, but "crap". The discussion on the emc-users
group was all about routing the step and direction signals via USB to a
USB<=>parport converter.

If it was a case of sending vector & velocity data to a smart controller, then
I would concur that it is viable. As you point out, there are a number of
devices now on the market that work. Why, there are even motion sub-systems
to plug in to ethernet and CAN bus. BUT they all use vector/velocity or
coordinate data and spit out the step/dir signals (for stepper motors). In
effect, taking the high speed loop out of the PC and putting it into a smart
controller.

Regards, Paul.
