UM2+ not printing well. Under extrusion?

Posted · UM2+ not printing well. Under extrusion?

Hello, My UM2+ used to print everything that I threw at it perfect with both pla(colorfabb and ultimaker brands) and petg(madesolid, colorfabb xt and makergeeks brands). I ended up taking on a job from 3d hubs where I printed a few hundred hours worth of petg at temps 250/70. That job printed great but now that I am trying to do my own prints everything just seems bad.

I have done several atomic pulls and even took the nozzle off and its clean inside. I am now trying to print with colorfabb pla that I have used before with no issues. Here is a picture of the first layer. It is very uneven where some spots are full/normal looking and others are very thin.

I am also getting a lot of lifting now, where before I never used to get lifting. Here is a 4 piece part that I printed that should be straight when put together but since the lifting is so bad it is way out of wack

Also, the bottom of the prints have these weird wavy lines:

Any ideas?

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
