FEATURE REQUEST: Outer Wall Wipe In Negative Normal Direction

[Psyonic 1]

Hi Guys n' Gals

I have been trying to get rid of blobs/zits and have found that the culprit (on my printer) is when an outer wall stops, the pressure in the nozzle forces out some extra material between when the X/Y movement stops and the retraction of the filament begins. I have a Bowden setup so there is some lag between a stop and the retraction relieving the pressure.

I found the "Outer Wall Wipe Distance" has not helped as it simply continues on it's path but it gave me a thought: If the "Wipe Distance" could move in the negative direction to the normal of the surface then stop, the blob/zit would be created inside the inner walls and therefore be hidden by the printing of the next layer...???

 

What do you think????

If you enable the "optimize wall printing order" setting then it already does what you are requesting. At the end of each outer wall, it moves into the print a little before any retraction takes place.

Really? I'll check that out, thanks.

 

It would be nice to be able to control how far this move travels

Thanks smartavionics, I just tried this and it helped quite a bit, but it still was not enough to completely remove the blobs. Is there any way to increase this distance that you know of?
