FLSUN QQ-S some problems

Can anyone tell me if Octoprint is compatible with FLSUN QQ-S ?,
Today I connected the printer to octoprint, it started printing and after a while the printer did not move anymore and quickly canceled the print and sent home.

Hello @Matias_Suarez!

Please do not delete the template. The required information are vital for dealing with your problem.


What is the problem?

What did you already try to solve it?

Logs ( octoprint.log , serial.log or output on terminal tab at a minimum , browser error console if UI issue ... no logs, no support! )

Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible )

octoprint.log (111.5 KB) serial.log (444 Bytes)
FLSUN QQS
Octoprint 1.4.0 stable

ver 2.3
MKS robin mini

So, sadly, the serial.log was not activated.
From the octoprint.log it seems you have communication problems with the printer:

The scrambling seem to repeat, so try another baudrate manually. Also have a look at this: OctoPrint randomly loses connection to the printer with a "SerialException"

Also this:

I have exactly the same problem with my FLSUN QQ

and we need exactly the same information in order to help you. See the first reply by @Ewald_Ikemann.

My problem had some history, I was adjusting the Eflow rate and botched it up, so I reloaded my firmware, after the firmware reload I was able to print one item but after that Octoprint wouldn't connect to my FLsun qq-s. I changed baud rate to auto and it connected right up. I'm sure you've tried this, just wanted to share.
