SOLVED SOLVED SOLVED

First... what a KICK ASS community - ya'll came to help a n00b quickly - provided good advice and examples

Extruder Temperature reset to 0 when print started
Cause: these three lines in the printer profile from Cura M104 S[extruder0_temperature] M109 S[extruder0_temperature] M109 R[extruder0_temperature]

**Fix - Comment them out. **
changing [ and ] to { and } didn't help

Part cooler fan not on at beginning of print
Cura had a deep setting under cooling for first layer fan % - it was set a zero - this put a fan off command (M107) right before the print started... caused problems. Change that setting to non-zero.

Changed title of this thread for next guy who Duets his Tornado and uses Cura. It's working like it should now and I don't have to fiddle with anything before I send prints. I have completed the Duet Tevo Tornado Cura transition. (I tried to put "solved" in the main thread title and it got flagged as spam).

Thank you folks in this thread for the help!
