    Hi everybody,
    now I have a fully functional mpcnc and it seems to me quite perfect!!! I’m very happy about this thing. Thanks to Ryan once again!

    But…
    I have a problem, in the middle of a work it happens that in repetier host I see the following message: “Communication timeout – reset send buffer block”.
    I have a 3m usb cable connected directly to the pc port…
    here is a complete listing.

    Is your computer falling asleep?

    my settings for energy saving on the pc are:

    – Turn off display: after 10 minutes
    – Suspend computer: never

    I have the same issue when printing 3D…

    Do you have ping pong checked or unchecked in the settings?

    Firmware: MPCNC marlin RC8
    Machine stopped soon after starts to print(most time it stopped after z movement, sometimes after first few lines).

    (endless)

    I have changed computers, cables(works on paper printer), the MPCNC is working under manual mode.

    sometimes, after manually input some movement, and start to print(with a pen), I got follow info and killed(all in a sudden, whole machine shakes).

    10:07:32.385 : Begin file list
    10:07:32.388 : End file list
    10:07:32.395 : echo:DEBUG:INFO,ERRORS

    10:08:17.434 : Error:Printer halted. kill() called!

    10:08:17.433 : echo:enqueueing “???? ?)Y??/???V?N ?0??_?” is what I got from display, I dont know what does that means.

    RC8 is the problem, use RC7
