For the GCodeSimulator:
at the moment the Material shown in Model details, for me shows guessed PLA 3.0mm
Don’t know how you do it, Maybe the Temperature for the MAterial, or it always shows PLA,…
but I only use 1.75mm gcode, which leads to a wrong mass Weight Price.
How about an Option to set the Size, Material, and maybe Price (which actually works for me with about 30€ p. Kg)
ok. for the PC version you can set environment variables to overwrite the guessed material/diameter. I need to add the options to the Android settings.
Okay, maybe I’m blind but I have no Idea how to do this.

you might want to try the new GCodeInfo App. Here you can configure the diameter , material and price per kg in the options.
