And it's still USB. Can it handle a 2500 line quadrature encoder? The control is the small part of the overall CNC conversion. I found that buying the CNC Cape for the BeagleBone which all around seemed like the lowest entry cost ultimately wasn't cheaper and it's sitting in a box.
This is not for closed loop servo that moves at a high speed. They likely just USB to LPT and reference a clock on the LPT side to Step and Dir for open loop.

So the minimum that the state can change on quadrature is 20mS. _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
