Fliament Coiling Up In Extruder

[540Designs 0]

I'm having trouble with MP Mini, it keeps jamming. The jam coils the filament up in the plastic spacer in the heat sink. When I break it down the nozzle does not seem to be jammed as I can push filament through with little pressure at 190 degrees. The print seems to go for approximately 20 min then this happens.

This is only happening on files I have created. I can print the test file that came with the printer and it continues just fine. But as soon as I try to print my own file, failure. I have included photos of my setting below. Any and all help is much appreciates. This is my first 3D printer, the part is not complicated.

I don't know the MP Mini printer but the Cura settings don't look wrong to me.

Have you checked if the cooling fan for the extruder stops working after 20 minutes?

I don't know the MP Mini either, so this is a *very wild guess*. But to me this looks a bit like you are using a 1.75mm filament in a 2.85mm printer?

However, if you would be using the correct filament, I would indeed look for a temperature/cooling problem somewhere in the system, like Nicolinux suggested? Or some piece of tubing or coupler that is missing or mounted incorrectly (similar to the white teflon coupler in Ultimaker printers), which is supposed to contain the molten filament?
