Adding another request for more advanced temperature controls. I've had to go back to Cura for my dual extrusion printer. S3D's tool change only handling method adds hours to each print, often requiring more time to be spent heating the tools vs extruding.
Here's an example
of the temperature control I'm getting with Cura, you can see the new tool comes up to temp while the old tool is finishing that layer, as soon as the old is done I do a quick purge into a catch bin, then I'm off and printing with only a 2-3second delay for the tool change max. In that screenshot you can see Cura detects that tool 1 is only getting a brief use, so it doesn't even bother dropping the temp on tool 0.
