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 )

3

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

4

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:

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.
