Update Baud Rate for Node
On first run, please make sure the baud rate is set
correctly for your printer. You can find this
information in your printer manual. Marlin now
mainly supports three baud rates of 115200,
200000, and 250000. The factory default baud
rate of Beam Node is 115200. If your printer
supports this baud rate, then leave it as it 115200.
If not, select the baud rate supported by your
printer, and then click Set Baud rate to complete
the setting. This setting only needs to be
configured once, and the Beam Node will store the
serial baud rate you set. If you switch Node to a
different printer, remember to check and adjust to
corresponding baud rate of the new printer.
