Ahhh, Was not clear to me that temp control or temp points didn't change when anything but material was changed. Was thinking to much into it and the dna200 uses the ohm reading to match up to temp points as a ratio. Makes sense. If material is the only consideration, then that list really should be added to Eclipse. Really shouldn't be that difficult I am a software developer and I will do that build for free, a port to Java for all you Mac and Linux users is another story Thanks for dealing with a newbie!
