Using Panel duet pins as serial interface
-
Hello,
I have a duet 2 wifi board that came installed in a Rostock v4 printer. I am attempting to use the serial interface on these pins to send a line of gcode and get back a response from the printer. I have modified the config.g file to have "M575 P1 B9600 S0" in it and it seems to be receiving and executing commands sent over the serial pins now. My problem is that I am getting no feed back at all from the board. Normally there is some kind of a msg back from the board indicating that the command completed. I am not getting any thing.
Is there some thing I have to do to enable acknowledgement msgs from the board?
Any help would be greatly appreciated.

Maybe you have to use the Marlin compatible mode to get the acknowledge messages?

Responses to PanelDue are held on the Duet until PanelDue sends a M408 command to pick them up. It's on my RRF3 work list to make this a configurable option.

What dose this mean for using the serial pins as the primary interface with "OK" responses from the board. I am in a bit of a jam here and using USB is not an option in my situation. Is this marlin compatibility mode an option? Dose that change the way the firmware works or just the response msgs back on the serial interface?
Thanks

Marlin compatibility mode just changes the responses, for example it appends the "ok".

So right now there is no way to use the displays serial pins in stead of the USB interface with normal response messages.
