Printer is jamming and failing everytime i print something larger

Ultimaker 3 with Simplify 3D

I use PETG and every time i print something over a few inches. My current project being an 8x4x6 in housing. It jams and fails during the print. What steps can i take to prevent this?

This is tough. You need to know if the problem is at the head or at the feeder. The problem could be at the head the pressure is very high or a clog or you are printing too fast and this causes grinding which causes it to fail.

Or it could be the feeder is slipping or too loose or too many retractions (do you have a lot of retractions right in a row? that can grind down the filament) such that the feeder is causing it to grind and there is nothing wrong on the head end.

That's a lot of possibilities. It would help if you knew when it was going to fail and examine the filament to see if it's grinding a lot and *almost* failing - such that the filament is no longer round after it passes into the bowden.

I guess we need more hints.

I have had no issues with printing PETG filaments although, I use the nylon preset with Cura to get that happening.

I am not familiar enough with S3D to give any answers. Have you tried Cura?
