1 and 2 sound like Smoothie problems and not anything specific to the Kossel. You might find better luck asking the Smoothie guys about those. They are pretty helpful and active on the Smoothie IRC channel.
- You need to find out what is causing the halt condition. Have your printer connected to a computer with the terminal window open, then send it a
resetcommand. It should report any errors through the terminal. Most likely, there is something wrong with your config or something is not wired correctly. After you send the
M999, it is normal for lights 2 and 3 to blink. This indicates normal operation.
- Again, this could be a config error or just something is not connected right. This may be related to problem 1. Double check your connections on the wiring diagrams from Panucatt.
- I would get the other problems sorted out first before you deal with this. Have a look at this guide on dealing with temperature issues.
If you need to upload your config file, use a service like Pastebin.
