What is the problem?
Printing stops due to communication error
What did you already try to solve it?
I tried to
- change USB cable
- change baudrate (in printer firmware too: 250000 to 115200 ==> same issue)
- new installation of octopi on new SD card
- add tape on D+ in USB port.
serial.log or output on terminal tab at a minimum, browser error console if UI issue ... no logs, no support!)
octoprint (4).log (4.1 KB)
And in syslog at the same time:
Mar 28 21:18:28 octopi kernel: [ 8864.390719] ch341-uart ttyUSB0: usb_serial_generic_read_bulk_callback - urb stopped: -32
Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible)
Octopi is always on undervoltage mode. i changed the power supply (but not official), same issue (power supply 5V/3A from amazon, now I wait a new one official)
I change the SSR of bed heating last week, because the last one remained closed at outlet and the bed reached MAX TEMP value. But now the bed heating work well.
Before updating octoprint and plugin, i never had this problem.
I have the firware updater plug in (and it's the only one installed). Maybe it's the cause of CH241 issue of syslog ??
Have you an idea to find the problem, because now, i miss one printing in two
Thank you (and sorry for my bad English)
