Some pics of benchy on my A350. I used Luban medium equivalent settings in Simplify3D.
In general, it looks okay and the dimensional accuracy is very good. There is a slight under extrusion on the top layer. It was originally under extruding by about 9mm. I recalibrated this, although perhaps it needs an extra tweak.
However, you can see on the cabin there is an issue with what looks like gaps between layers.
On the longer hull runs it looks fine. However, on these shorter runs, especially with hard corners there is an issue. Could it be retraction?
I also was about 10mm off on my extrusion. E-steps are now at 235.8 from the default 212.21 setting and my retraction is set to around 1.0mm which is down from the 5mm I saw in Luban. I am using PrusaSlicer with my A350 and will be happy when i can achieve a level bed.
What settings for print? Also do you have shots of bottom of benchy and the back for the fine details. I did print one after I felt it was dialled in. Will post later.
