klipper infinite LOOP once getting in halted status

WindoACWindoAC
in Bug Reports
I found RS default setting have issue at halted status handing for klipper. Due to RS will send commectionCommands once it got "!!" (halted signal) and Gcode M220 / M221 / G92 / G90 / M82 / M117 will make klipper resent the halted information. It cause RS looping to get the error info and make the RS stop working.

I workaround to change the startup script from 

    <connectionCommands>M105
        M115
        M220 S100
        M221 S100
        G92 E0
        G90
        M82
        @getip
    </connectionCommands>

to

    <connectionCommands>M105
        M115
    </connectionCommands>

and no infinite LOOP after error.

    Thanks for the log. Comparing with sources it is clear what happens. !! calls halted signal which resets the printer and starts again. I now have changed it so halted will deactivate the printer so it will never connect on it's own. You will have to activate it to use it again.
  • WindoACWindoAC
    I think it won't work if user try to active the printer in this status immediately. And the result will be user not able to enter the command interface to input "#FIRMWARE_RESTART" to reset the printer.

    I suggest change to not send connectionCommands when printer halted.
  • RepetierRepetier
    I see what you mean. Would require a bigger mod as that state is not implemented. Originally only gcode was planned. Now gcode does not work but special firmware commands do:-( But ok, will make a switch to disable gcode and send a error notice every time user tries to send a gcode to remind him of the problem. Think that should do it.
