I'm trying to connect Octoprint to a UM2+ clone running a Lerdge S 32 bit board.
For months it has kind of worked albeit with the occasional delay ( press home wait 20 seconds or so for the printer to react) but since the recent upgrade, i cant get any response out of the printer.
The Lerdge 32bit board is unfortunately closed source. However, all configuration that would typically be in config.h, takes place thru the provided touch screen and works great.
The ledge board needs a plug-in adapter to provide serial communications ( which also has a socket that accepts a ESP8826 wifi unit)
So while testing i have removed the wifi unit ( for fear of it interfering with serial comms). If i connect a laptop to the printer and run Pronterface it works fine and prints and accepts gcode commands (115200 baud). So I'm a bit lost as to why it doesn't play nice with a Raspi3 running Octoprint ( and nothing else)
I know the Raspi / Octoprint are fine as if i connect them to one of my other printers the work without issue.
I have found the "serial logging' option in Octoprint but need some help on how to get the log file "off" the raspi.
While i consider myself relatively conversant with the working of 3D printers, my Linux skills are sadly lacking.
All help advice appreciated
