Where do I learn how to make models that actually print. Their dumb cat prints but anything I have gets messed up. I have tried playing with all sort of settings on the printer as well as in Cura but at this point, I am just guessing.

For example, when one of my objects starts printing it starts to make a rectangle about 2" x 1". The back left corner always gets pulled inward as the extruder moves counterclockwise rounding the back left. It’s always this back corner so I don’t know what that means. thx

Hi, sounds like your print bed is too low on the back left corner. The cat prints well because using a raft can make up for poor leveling.

I suggest you check out the Monoprice Mini Select user group on Facebook. They have lots of tips and suggestions for tuning it.

Good luck!
