Tried it out on the Bottom_corner part, to see how it went with ooze and overhangs.

In both of these issues it’s proving a challenge, but part came out looking otherwise very nice in 37m.

The problem with overhangs is documented really well here: http://www.akeric.com/blog/?p=3407

As for retraction, I’ve tried bumping up travel rate and retraction length – up to a ridiculous 10mm, which came close to causing a clog, and was no better than 4mm.

I’ve played with retraction speed and print temperature too. Just won’t go away. I’m guessing you’d need a different hot end design to allow the length of retraction really needed to stop ooze at this print volume.

Looks like these issues are ones I might have to live with
