now octoprint alert me wich the a problem with voltage...but when I used repetier server no problems....no problem of timeouts ...not even voltage

message: "undervoltage. make sure your power supply and cable....ect ect.

If OctoPrint is alerting you to an Raspberry Pi power problem, you have a power problem. The Raspberry Pi is detecting the power problem, OctoPrint is only passing it on.

Were you running repetier server on the same Raspberry Pi?

lol not at the same time. of the old configuration with repetier server I made an image. then I took the octo print package and created a new sd only with octoprint.

how I can resolve the problem of voltage?

You need to use a proper 5v power supply (i.e. not some random charger) that has an amperage rating high enough for your (unknown model) Raspberry Pi. I'm guessing 2.5-3.5 amps. See below for more information.

thanks. the power supply, I don't remember what amperage it has. I use what they sold me along with rasberry. I'll watch it.
In any case, could the timeout problem be due to low voltage? Or are they separate problems?

Yes. ANYTHING weird, from network disconnects, to printer disconnects, to communication issues in general, half loaded webpages, errant behaviour, can be due to undervoltage. That's why OctoPrint tells you so adamantly to fix it when it detects it.

now the voltage is fine, no more messages. but the problem persists.
I set the boudrate to 25000, it seemed to have solved the problem. In fact, the connection to the "go home" command was no longer blocked, but I tried to send a print anyway, and it stops after a few seconds of printing

Now that you have the power problem fixed, we need a current set of log files (both octoprint and serial). Remember to enable the serial.log. Please upload the complete files.

I see we need a lesson in how to upload log files so that others can read them. When I said upload complete files, I meant upload the file itself, not the complete contents. Also, when you upload machine generated content, please use the </> icon above to prevent the forums from interpreting the contents as markdown (special character sequences which apply formatting to the text).

It does appear that the printer and the RPi are communicating but there was a communication error that did not get handled properly. Because the log upload was subject to markdown processing, we can't determine exactly what might have gone wrong. If you can upload the entire log file (drag and drop it here), maybe we can preform a more through analysis.

sorry. I'm a Nubbie

serial (1).log (245.5 KB) octoprint (2).log (57.2 KB)

Maybe a Nubbie but learning fast! Thanks for useable copies of the logs.

I see a couple of problems. In your initial post, you state that you didn't run in safe mode. Doing so now will eliminate any issues with plugins and the octoprint.log shows problems with at least octovox.

The lost connection issue appears when the following is sent:

2021-04-08 22:50:07,521 - Send: N174 M117 ETA is 11:28:14 pm*126
2021-04-08 22:50:07,541 - Recv: Error:No Checksum with line number, Last Line: 173

and I believe that line is generated by the plugin Octoprint-Display-ETA. I don't see anything wrong with the line and it does contain a checksum but the firmware doesn't like it for some reason. If safe mode works, please disable that plugin and see if it is the cause of this issue.

The version of Marlin (1.0.0) reported by this printer is ancient. I don't know how heavily modified the firmware is, but if it is possible to upgrade to a newer version, it would probably be worthwhile. Note that since it is Marlin based, the printer manufacturer is obligated to make the sources available.

Some firmware has issues with : and treats that as a line separator. That would result in this M117 line to be considered 3 lines by the firmware:

N174 M117 ETA is 11
28
14 pm*126

The first having a line number but no checksum, the second having neither line number nor checksum, and the the last having a (wrong) checksum but no line number.

Get rid of the plugin, reconfigure it to not use : or flash a different firmware that doesn't hiccup on : in M117 commands.

thanks ,,, sorry for late ...
I deleted octovox, data and plugin

so ... i restarted in safe mode
start print
first test OK !!!! printed!

but if I restart normal and print the same file, the printer losts communication .... so ... maybe another plug-in is the problem .
... is there a test to know what plugin is not good? ... ....

I have no idea why you deleted Octovox after @b-morgan already (IMHO correctly) diagnosed the issue to be Display-ETA:

...I reainstalled image all from begin.
I reinstalled octoprint whitout plugin.
result: printed

well
so I try to install few plug in... one by one.. step by step...so i install one..and I try if print...if ok I'll create a backup and so on..(about it...when I create a backup...what's save?... the plug-in are inclused?)

Yes, plugins & their settings are included.
