Ok, went to file/New, added a couple of stl's, confirmed process1 was applied, preview window shows the slice. still a 0kb gcode output. saved factory file as test.factory
went back and opened the first factory file attached above- it has one of the stl's in the model list, but preview is blank and the second STL isn't even in the list. The models are not saving in the factory file. the process wasn't saved either- do you have to have a model to have a process?
reopened test.factory attached here and found the same result- one model in list, nothing in preview, second model not in list, no process saved.
I have a dual extruder printer T0 / T1, have used for years, could that be something? I have not done any dual extruder setup , I just set up one process for one extruder T0 to get past this issue. Normally if you are single extruder it is tool 0 and the heat bed is tool 2, if that's the way ramps/marlin is set up (which mine is).
Thanks for any and all help!
