host software problems

I have a gen 2 sanguino darwin, and the firmware all works. I can get the temp, move motors etc.

The host software is almost completely not working. I can upload stl files and it acts like it's printing them. But, the motors just sit there and click, and the temperature is not right, as it sits at zero. It's not the pins, I have checked like 1000 times, it's not the g-code firmware I uploaded, because it's exactly what was put online.

Thoughts?

What OS are you using?

In the host software preferences turn on debugging and comms debugging. Now watch the output to stdout to see that information. You should be able to see it polling the temperature and getting a response.

If that doesn't help, you can use a serial terminal program to send commands manually. I used GtkTerm on Linux. Send "M105" followed by a newline character. You should get a response from the microprocessor that looks like "T:22", where 22 is the room temperature. If you don't, then the problem is in your firmware or wiring.
