S3D v2.1 If I export and then re-import a profile it appears that not all information is saved. Example follows.
Choose profile MakerBot dual extruder (left). Make changes, then export.
Close down S3D and restart. If I then configure a new print and import the profile saved above, everything appears to be fine. However when I attempt to print the job is sent to the printer - which then hangs without the extruders being told to warm up. If I manually set the temperatures then the job proceeds as expected.
If however I use the MakerBot dual extruder profile from the dropdown list the job executes as expected with no requirement to manually set the temperatures.
It therefore looks to me that exporting a profile can't be saving all of the salient information for the profile - when imported back in something is missing.
