Has anyone tried one of these usb controllers? I’ve ordered one and it’s supposed to be compatible with Mach 3.
Yep works great.
There’s another posting that has the directions for setting up Mach3 and a new set file so it can use all the buttons. Just do a search for Mach3 controller or pendant and it should pop up for you. There’s also a link for a YouTube video for how to create your own file if you want to map the buttons to something different if you want to.
