usb communication problem (i think)

gianluca · February 7, 2016, 10:44am

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?

gianluca · February 8, 2016, 9:18am

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…

vicious1 · February 8, 2016, 10:24am

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

gianluca · February 8, 2016, 10:42am

i’ve tried both settings. checked and unchecked, same result…

Has anyone discovered the solution? I have had this same problem many times over.

Hi, I have this problem too, I used test.nc file from https://www.v1engineering.com/wp-content/uploads/2015/09/Test-File.zip
Host: repetier 1.6.2
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).

10:08:17.433 : 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
