Not yet, at least not in any way that most users would consider reasonable. You could program the entire toolpath path in very short moves, punctuated by M72 or M73 commands to wait for input from the EDM power supply, but that'd be kind of a pain I would think.Is it possible to pause the Turbocnc software then restart it through some kind of input recieved from the EDM power supply.
This sort of thing has been on the slate for eventual addition to the code, but I haven't gotten around to it yet.
