I had been doing Atomic Pulls with darker filament, thinking it would show left over filament from the white print. I switched to white and immediately realized I still had residue in the nozzle. After several more pulls, all the residue was removed and subsequent prints came out good. Lesson learned. Thanks for the tips!

I have gone through the troubleshooting guide, but I hadn't seen the advanced tips section. The picture of the Ultimaker Robot looks just like one I printed last night. Thanks for the link, Labern!

Hello, I'm having problems with under extrusion on recent prints. The print comes out with visible lines and is very easy to break. This happened once before and after many Atomic Pulls and re-leveling the bed it went away entirely for a couple weeks. I once again tried leveling the bed and clearing the nozzle, but so far have not seen an improvement. I also tried varying the temperature between 210-230, using different filament and different files. I'm using PLA on a UM2 extended. I've had this printer about a month and have been printing almost constantly. Any ideas on how to correct this? Finished print. Broken cross section: Any advise would be welcome! Thanks
