Ultimaker not connecting after firmware update

Recommended Posts

Hi,

I'm very new to all of this so please bear with me. I had some problems with printing (print wouldn't start, while everything up to the point of printing went fine), for which I decided to update my firmware. I upgraded to marlin build 3 and now I can't connect to the ultimaker PCB. More importantly, I can't get the default firmware back in. Does anyone know what to do?

This is more of a RepG problem then a Marlin problem really.

Or more of problem with people just changing defaults. The communication baudrate has been changed a few times now. It used to be 57600, but Marlin already moved to 115200. But there are also 230400 versions, and I think the latest uses 250000.

In your ReplicatorG install directory there is a /machines/ folder, in there there is an ultimaker.xml file. Open it in a text editor to change the baudrate (it says "57600" somewhere)

Or give PrintRun a go:

http://reprap.org/wiki/Printrun

which allows you to set the baudrate when connecting. (I noticed I have to press "connect" and then "reset" for it to work)

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
