Extruder clearance
I am sorry if the answer to this is RTFB, but I couldn't find it, and it's nice to chat about stuff anyway.
I'm talking about the "Complete individual objects" option in the "Sequential printing" section.
It asks for the radius and height for the extruder clearance. Radius is fairly obvious, but assumes a round shape, and I am not so sure about height, unless it means the height of the rails.
What I have actually come here to ask is if there is any way to modify the parameters, because my extruder is a long way off round.
This isn't usually a problem as long as I print objects at the front of the bed first, but the "Arrange selection" option doesn't appear to consider that.

Hi @Hairyloon!
After reading this post, I said to myself “wtf is “Sequential Printing”” and how can I learn about it.
So, I RTFM…
And, my take-aways are as follows:
1). “Round” and “radius” are to define a basic KOZ (Keep-Out Zone) and “Height” is the “vertical distance between the tip of the nozzle and the X-axis rods (or the lowest part which may interfere with a finished print)” (from the manual). They want to avoid the X-axis rods (which let’s just say have a distance of 5 units from build plate to the bottom of the lowest X-a is rod) from impacting say object “A”, with a height of 10 units from base to the first X-axis rod when it starts to print object “B”…
I think…
2). The logic/algorithms that are used to slice seem unable to deal with a second (or third or more) objects that have Z-heights that would cause collisions if the are in the same Y-plane, so you have to stagger higher objects to the rear of lower objects, I think…
3). One thing they (The fine folks @Prusa) should add is that Sequential Printing also provides an opportunity to remove parts from a running print job prior to the entire job being completed (with a caveat that one may botch to job if they jog the print bed when they remove the part)
4). I do not think the “smarts” to auto-arrange parts when using Sequential Printing are baked in, so, if one was using Sequential Printing, it would be good to have that option disabled (greyed out), me thinks…

Thanks a lot for the suggestion, I'll try turning it off for a while to see what happens
