Support more baudrates

[peteruithoven]

We'd like to support more baudrates than we currently do. Currently we only support 250000 and 115200. This is needed to support for example Cupcake printers.

I got this request from one of our users. Can we add support for a custom fixed baudrate where the box won't be trying all those different values to auto-connect?

Eric T: I have a ultimaker original running with the marlin software (so I use machine = Generic Marlin Printer) since I have a heated bed home build and a different hotend. I have changed the baudrate of the printer to 230400 which is a more standard baudrate so I can use cura for firmware upgrade using ubuntu (ubuntu does not support the none standard 250000). From the logging of the doodle3d I can see it tries to connect with 115200 and the 250000 but not my 230400. I found the api documentation on http://www.doodle3d.com/help/api-documentation
and with that I was able to change for example the printer.temperature. But I am not able to change the baudrate since that is not an integer value but a string. I have no clue on how to do that.
For example when I try this:

`

<textarea name="printer.baudrate">"250000"</textarea> `

Then the response is
{"data":{"more_info":"http://doodle3d.com/api","substituted_ssid":"Doodle3D-B12C8C","substituted_wifiboxid":"Doodle3D-B12C8C","validation":{"printer.baudrate":"could not save setting ('Value isn't a valid int or float')"}},"status":"success"}

I guess I am missing some elementary html knowledge here but google did not help me yet.
So how do I do this?

Having a baudrate option in the settings menu would helped without going into this low level stuff.

At the moment the wifibox tries different baudrates to autoconnect to a printer. I think a mode where autoconnect can be disabled and the port and speed can be set manually would be useful.

I've split up and moved this issue:

• Store baudrate per printer? print3d#24 (Store baudrate per printer?)
• Improve connect step print3d#23 (improve connect step)
