Here's my modifications to Ishy's settings! 

 

Profile is attached!

 

NIH Prusa RC3 Remix from 5:50 to 2:51 estimated using these settings. I'm working on bumping speeds up still, but this is a significant improvement. Will post pics of the most recent one. Thanks everyone for their help! If someone knows better on any of these settings please speak up!

 

Settings exported in Gcode using:

 

 

%%$ This setting may not be allowable for water-tightness %%%

 

; Fill Gaps Between Walls : Nowhere ;saves material and 40min for a NIH RC3

 

%%% These settings are what matter for quality %%%

 

; Z Seam Alignment : shortest    ;Z Seam and corner preference seemed to help surface finish on the NIH RC3 hair shield portion
; Seam Corner Preference : z_seam_corner_weighted (Smart hiding)

; Combing Mode : off         ;This prevents stringing, but does increase time. Originally on "Only in skin" but had trouble once I bumped speeds up.

; Fan Speed : 10         ;This helps layer adhesion for PETG
;  Regular Fan Speed : 10


%%% These settings are what my community are using for the Prusa RC3 facesheilds %%%

 

; Layer Height : 0.3
; Initial Layer Height : 0.3
; Initial Layer Line Width : 100
;  Wall Line Count : 3
; Top Surface Skin Layers : 3
;   Top Layers : 3
;   Bottom Layers : 3
;   Initial Bottom Layers : 3
; Infill Density : 30
; Infill Layer Thickness : 0.3

 

%%% Print speeds are being worked on seeing how far I can push it, but here is what I have tested working %%% 

 

; Print Speed : 60
;  Infill Speed : 50
;  Wall Speed : 50
;   Outer Wall Speed : 35
;   Inner Wall Speed : 50
;  Top Surface Skin Speed : 35
;  Top/Bottom Speed : 35
;  Prime Tower Speed : 35
; Initial Layer Speed : 20
;  Initial Layer Print Speed : 20
;  Initial Layer Travel Speed : 83.33333333333333
; Build Plate Adhesion Type : none ;save material during priming

Sorry if I'm posting too much but I just pushed a few of the numbers as much as I could, and though it's borderline acceptable, I'm curious what EXACT setting is the main one to consider for improving the top layer as shown in the photo.  I got the time down to 2 hr 44 m and though it's ALMOST working, this is what needs adjusting. Any help? I bet it's something simple that I'm just overlooking.   Thanks people 🙂

    Hey guys,

    I used mhigginsmoy settings from above and they have improved the print greatly on the two UM3s that we have in our mini-farm. We have three Prusa MK2Ss that are running circles around them and performing flawlessly. Not to belittle the Ultimaker, but I believe the week link here is Cura. The files for the Prusa's were sliced using Simplified 3D. And for the life of me, I can't get any gcode from S3D to run on the 3s.

    Well down to my real question and dilemma. This is what we are getting from the U3s. A little weakness in the Z. If twisted they crack a little. But it's the zits and voids that I can't get under control. The stringing is a non-issue now.

    You should be able to get quite good quality on the walls with PETG on a UM3.

    Example here is a simple tool rack but coming out nice with most of the settings as of the cheat sheet.

    Wanted to update with a picture using my settings. Print time is 3:20 for the NIH Prusa. I wasn't able to speed up the print as I had hoped without detriment to the quality - eg layer adhesion.

      • 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.
