Command finished acknowledgement



  • I really could use a "Command finished acknowledgement" so that I know when a command has been completed. I am using several Duets on a project that requires me to know when a move command has completed. The "ok" reply is not suitable as it is not sent upon completion of the command but rather it is send some time around the beginning of when the command is being executed. Is there such a command or method for achieving this please? Thanks in advance !

    If you use M555 to put the firmware in nanoDLP mode, it will send an acknowledgement after each move.



  • tHANKS SO MUCH FOR THAT -- i SEARCHED AND FOUND NOTHING SO THAT IS REALLY HELPFUL !!!

    wHOOPS, CAP LOCK IS ON 🙂



  • @dc42 The M555 command seems to work, but behaves in a strange way. For example, if I send a G0 X10, it will reply with "Z_move_comp"..... and then "ok"..... why Z?

    An alternative is to send a command (and perhaps get an "ok" depending upon the command), then send an M400 and await an "ok" reply to the M400 command.

    Because that's what nanoDLP expects.
