Instead it simply tries to service the USB port at a regular service rate, which is not guaranteed. However, this mode does not possess any interrupt ability.
It seems that USB has a poorly named communications mode often referred to as interrupt mode.
So my plan is to take the information from the ring buffer and compose messages to send over USB to the hardware.Ģ. The motion driver must take this information and feed it to the hardware. First, it seems that Mach3 holds timed step information in a ring buffer that gets filled by Mach3. So I wanted to do a RFC to get feedback on how I plan to implement my solution.ġ. Being a fan of OSS and already working a couple OSS projects I decided this would be a great OSS project. I could be providing a solution for others and not just myself. I was about ready to start writing code when it hit me. I've read all I can find on the subject and have installed older versions of MSVC. I've been researching what I can find on implementing a USB motion plugin for Mach3. I wanted to use USB as a communications medium and found that Mach3 doesn't support motion control over USB. I recently decided to try my hand at building my own stepper controller board.
