This post may relate to temperature problems within the Marlin 1.0.0 B1 firmware.

I started using the new Marlin, and so far it's great, other than the build in speed limit.

The picture above is printed/generated from a0.2mm profile in netfabb, printed at 225 deg, and max speed: 500% (300-500mm/sec?).

The first 35mm went perfect, the surface is really nice and shiny.

Then, suddenly at 35-44mm, the extrusion stalls, and looses it's shininess... the temp setting/reading is still the same (225), but the extrusion is forced, and gets a new surface:

a lot of fuzzy surface. Then between 44-52mm the extrusion becomes incomplete (no adherence, big holes etc), and the only way to bring it back is lowering the speed (back to 100%), from 52mm upwards. I tried increasing the speed back to 200%, but it also produced matte extrusion eventually.

Bernhard, let me know what additional info you need, if it is indeed FW related.

      • 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.
