Total cnc noob, several years vb coding and considerable uC/embedded programming exp.
Again Im just getting my feet wet w/cnc, so be gentle. Is the goal of the VB project to have the pc run the motors realtime? If so I think this will be very difficult w/any windows based platform.
I would think a better approach would be to have an uC based controller run the stepper drivers while being updated by the pc. Isnt this the typical operating scheme for cnc?
I can tell from exp attempting to use vb.net < version 3.5 (2008) has some severe bugs in IO components. Since version 2008 tho I havnt expd any issues.
Im very interested in this project.
