Posted · UM2 Upgrade kit - Problem printing rads at the base of a model

Since upgrading to the new UM2+ upgrade kit i have noticed my printer seems to print rads at the base of the model really badly.

See below, the brown print is before i upgraded, and the green after. Okay i know the materials are different but they are both the same standard pla, just different colours, and this has been happening on all my prints since upgrading. The settings are both the same between the green and brown.

I also noticed my prints seem to curl up a load more at the edges of the early layers, before the upgrade the adhesion was really good, now not so.

Layer Height: 0.15

Speed : 2500 mm/min

Nozzle temp : 200 deg C

Bed Temp :60 deg C

Any ideas? I am wondering if the better fans/ducts are making it too cold at the edges and making it curl up and spoil that part of the print.

      • Release Notes: S-Line Firmware 8.3.0 (Latest)

        Dustin posted a topic in Firmware,

        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.
