What is the problem?
I have been using Octoprint with a Prusa i3 clone and it has been working like a champ. Recently I got a cheap CR10 clone and setup a new Octopi server on a Raspberry Pi 3B.
Octoprint seems to detect the printer, connect to it, but after that, fails with errors like the following
Recv: Error:No Line Number with checksum, Last Line: 0
Send: N1 M115*39
Recv: echo:SD card ok

What did you already try to solve it?
-
I've tried different baud rates, it fails with all other ones except for the one it auto detects.
-
I've tried swapping USB cable (with the one that was working for the i3 clone), no dice.
-
If I start print from SD Card it prints (kind of, currently clogged itself up because the fan wasn't working, that's a different story).
-I don't think it is an Octoprint bug, could be the USB serial chip has a weirdness because the SD card that came with it has some drivers which I am sure don't work for Linux.

I would like to upgrade to the latest Marlin, only if I could find all the custom settings for the printer. I've asked the vendor and waiting for response.
Any pointers or guidance, much appreciated. Thanks.
