Finally happy with this print quality!
After gluing my bowden adapter ring back into its housing and tweaking my bowden path a little, and also reducing my retract speed (3600mm/min is too much even for the might bondtech!).
Generally pretty happy with this result now, I have a couple of small holes in the top layer near the front right of the bow, not quite sure how they’re sneaking in, perhaps my filament is slightly smaller than I specified, and there was one random string when the head moved from the tip of the bow to the cabin area, again not sure what caused that but I think mostly an anomaly. Good enough now though I think!
Tips for those tuning:
-
If you think you got your E steps right the first time, think again, go back and try again. Mine was out by almost 4% even though I could have sworn it was correct last time I set it.
-
Use Eric Liens settings, they’re good:
0.5mm extrusion width
5.5mm retraction distance
-0.1 extra restart distance
1500 retraction speed
0.2mm coast
If you’re using Simplify3d, use the ‘Only retract when crossing open spaces’, and ‘Force retraction between layers’ settings also.
- Ensure your filament doesn’t have a knot in it! (yes…no idea how that happened but the filament must have got under itself at some point and created a knot which definitely will ruin your day).
