+# 3DPrinter-Remote
+
+Provides remote access to 3DPrinter. Add-on runs ser2net and can be connected to by e.g. socat.
+
+## Usage
+
+On the machine connected to the printer (`remote machine`):
+* Setup the add-on. At minimum you will need to specify `printer_path` and verify that `baud_rate` is correct.
+
+On the machine with OctoPrint:
+* Go to Settings --> Serial Connection, section __Additional serial ports__. Add : `socket://<remote machine>:9999`. For example, use the IP for `remote machine`.
