Is support material considered open space?
I've been playing around with retraction settings because I'm attempting to print a part that is primarily support for the first half of the print. I had trouble with the extruder head rubbing against the support and ripping it off the bed so I bumped up the retraction vertical lift to avoid contact. However, the bed is jumping around while printing the actual part and I want to avoid that. I have the "Only retract when crossing open spaces" box unchecked, but I was wondering if I could still have it avoid the support with it checked.
Any advice would be greatly appreciated.
