Hey I just got mu first ever 3d printer of Facebook marketplace. A monoprice mini delta v2 and I cant figure out how to get printing working. I have inserted filament and tried so it work and it does. Then downloaded the poloprint cloud app. But when I click print it sends to the printer and then it says slicer error. I dont know what Im doing wrong.

Note I do not own a computer so the app is everything I got. Would love for help and tips
