It's called OverrideGC Temp which essentially allows you to set the temperature for printing on the printer instead of when slicing so I can switch from ABS to PLA without reslicing and it works great. I still have to re-level the build plat until I install those aluminum arms I got.
In my searching for an alternative to tan for lithophanes I tried some gold PLA from ToyBuilder labs and... it doesn't work. Too transparent. maybe I can find a thickness where it will work but I'm guessing it'll be really thick. So no gold for lithophanes. And still, I search.
