#1

Hello,

I have a problem when I lunch a printing gcode with octoprint interface, the printer have a problem when it goes from layer 1 to 2. The connection is close and my ender reboot ...
THis message in octoprint :
"Communication error

There was a communication error while talking to your printer. Please consult the terminal output and octoprint.log for details. Error: Too many consecutive timeouts, printer still connected and alive?"

I have last update of rapsberry and octoprint is in 1.5.0

But when i lunch same gcode in SD card directily from ender, I don't have problem.
And the USB connection don't have 5V just GND, D+, D-.

octoprint.log (97.3 KB) serial.log (3.8 KB) Terminal info gcode.log (9.5 KB)

Thank you

Your printer stops responding to OctoPrint altogether here:

OctoPrint needs a reliable serial communication with the printer to work. Could be a firmware issue maybe, but it's hard to say since your serial.log doesn't contain an actual connection to the printer, only a failed connection attempt.

Thank you for your answer,

I have test many impression today and I change the USB cable.
In this impression have 6 rest for 10 printng without change setting or configuration ....
The rest is between 1 and 2 layer. If the layer 2 printing; I don't have problem of all impression.

Do you have any ideas ? Or other log for help me ?

thank you

I have check firmeware, and i change this for 1.1.6, same problem, 1.1.9 the same ....
It's possible that Octoprint is the problem ? If I reinstall all It'possible to solve my problem ?

I'm not aware of any way that OctoPrint can make the printer stop responding by simply streaming a gcode file to it, and that is the problem here. Your firmware stops responding. Maybe it crashes, maybe it just takes really long to process whatever it is processing, but the result is, it stops to reply to OctoPrint and OctoPrint gives up after a while.

Current mainline Marlin is 2.x. You should ignore anything provided by Creality as it's known to be broken anyhow and instead go with a build of the current mainline Marlin release.

I have the same reboot issue but it is random.

Can you explain about usb cable?

#7

Why do you use only GND, D+,D- ?

Bye

Because +5V is not necessary for the serial USB connection. Sometimes it is causing issues.
