RE: 0.6.0 Issues (No LCD status, 500 error)
Hi, I am sorry, Since your post, I've walked someone through this and it turns out pronterface checks the gcodes, since PRUSA SN is custom, it does not pass and pronterface does not send it. This cannot be turned off. I have not known that and did not think to check for it.
I have not tested it, but this looks like a promising serial console to use. https://www.compuphase.com/software_termite.htm#_
But if you managed to connect using pronterface - the printer reset after you clicked connect, you might be done, so try and re-enable the rpi port and power cycle the printer to reset the pi. The wizard might work now.
Alternatively, can I invite you to our Discord server? It allows for a much faster back and forth for any sort of troubleshooting. Thank you

Pronterface gives me also the response "Unknown Syntax" Octoprint´s terminal worked on the other hand for me.
