Thanks Clayton,
I was up till 2am last night trying to figure this one out, and seem to have struck the solution before reading your email. What I discovered was that T1 refers to the Bed Temperature ('This is a Heated Platform" needs to be checked), while T2 refers to the extruder temperature. Adding a setpoint in the menu (on the right) to the highlighted Temperature Control (on the left) - either Extruder or Bed, did the trick. I just had to make sure I picked a Temperature Identifier from the list of 4.
I think that's basically what you recommended, only it seems that each temperature needs a 'Temperature Identifier' specifying.
Thanks for your advice!
