Define serial 1

Sign in to your account. I'm attempting to control a marlin based printer over direct serial using the UART pins on a raspberry pi 3, however the connection simply times out without any response. Expected behavior: [What you expect to happen] Communication established, printer responds to temperature requests, etc. Just for clarification, the wires hooked up to the Rpi3 are using a voltage divider to bring the 5v down to 3. The text was updated successfully, but these errors were encountered:.

Please test with the latest bugfix If the problem has been resolved then we can close this issue. If you still see the bad behavior we should investigate further.

Sorry, something went wrong. OK tested with 2. So it looks like setting the primary serial port to 1 produces bad behavior on both firmwares. Online documentation for this really could use an update. Every tutorial I've looked up about this had no mention of the serial port being the same or different.

We haven't really got a section devoted to Marlin bit and the expanded options just yet. Apologies, I thought I'd already replied to this but apparently I forgot to hit the send button.
