Problem with extruder drive

I have upgraded my Omerod1, (one of the first #445) from some old SW maybe version1.09 -> 1.17e, and DWC1.14
When I manual extrude first time it's ok, but next time I press on extrude button, the extruder turn direction, and next time again it turn again, and so on.

What have I forgot?
I have read the upgrade notes, but.....

#445

maybe the wires on the motherboard need to be connected in reverse?

The extruder will work only if the nozzle is hot. The big gear should turn clockwise when you click "extrude" and anti-clockwise when you click "extract". Is that what is happening? If it is turning the wrong direction, you can either reverse the wires on the Duet, or add the command to your config.sys file "M569 P3 S1"

Thanks, I look like a problem with the nozzle temperature. The temperature wire was half broken.
Now it works again.
