Yes, there are WAY to many different types of plastic out there to have just a few listed. I know how to make the changes, But I am thinking someone will not know what they are doing and select these and jam their machine.
I can see a place where there are defaults for the Novice user, but also the ability to add new plastics as needed. Most will use ABS and PLA, But some might use HIPS, PC-ABS, NYLON(many different types), Wood, stone ect..... temperatures will vary a bit depending on environment. Maybe a simple Drop Down that can look to a flat file for the information that can be changed by the end user.
Tying the Bed to the type of plastic will also help.
There are things that Slic3r does that makes a bit more sense. We just need to roll those items into Simplify to make it even better.
I have used Slic3r since they came out with it. Before that I exclusively used Skeinforge. Simplify3D has the potential to be the best out there. I have moved over 90%..... I look forward to moving 100%...
Lets make this software the KILLER app of 3D printing software.
