· Severe under extrusion and filament flow issues?
I don't know this slicer so I don't know what the extrusion multiplier of .8 does exactly but it sounds like it would underextrude by 20%. Are you sure that's correct?
Too cold, too fast. Your bottom layer is .35mm thick, with .4mm nozzle and 60mm/sec that is 8.4 mm^3/sec. much too fast for 200C. Try 240C if you are going to print that fast or slow it down to maybe 10mm/sec for the bottom layer, then 20mm/sec for the rest. The UMO can print that fast at 240C but you are still pushing it a bit. I recommend you print at half maximum speed as shown below. For the bottom layer of course it's almost twice as thick so print half these speeds...
Here are my recommended top speeds for .2mm layers (twice as fast for .1mm layers):
20mm/sec at 200C
30mm/sec at 210C
40mm/sec at 225C
50mm/sec at 240C
The printer can do double these speeds but with huge difficulty and usually with a loss in part quality due to underextrusion. Different colors print best at quite different temperatures and due to imperfect temp sensors, some printers print 10C cool so use these values as an initial starting guideline and if you are still underextruding try raising the temp. But don't go over 240C with PLA.
Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
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.
