Case when "Z hop" will do more harm than good.

Investigating large rate of failure, I found that "Z hop" was the setting that was a culprit. But conditions are very specific.
Any considerations of support would be greatly appreciated!

I frequently use z hop with PETG. though I've learned to keep the hop height to no more than the layer thickness, maybe a hair less. just enough to keep the nozzle from dragging parts off the print bed, not enough to leave a random extrusion that extends past the next layer, to be struck by the nozzle later

Holy crap, are you printing all those small parts with All at Once on? They are the PERFECT opportunity to print with the One at a Time setting! The overall print quality shoots through the roof. Especially with PETG, you are also reducing undesirable part cooling.

Indeed was about to say the same, the ( one at a time ) setting is very good at doing multiple prints at the same and it completely avoids the issue this guy is having, I used it recently when i was printing cable chain parts for my new Ender 3 and due to the amount i needed slapped 20 of them in cura and printed but got a lot of stringing even with good retraction settings resulting in prints that needed way more clean up than i wanted, then found the one at a time setting and it worked flawlessly with perfect prints, only down side is if you have a small bed you have to reduce the print quantity due to the head movement grey box, in my case i went from 20 all at once to just 9 in one at a time.

@@EQINOX187 Yeah, One at a Time works better on my Ender 3 Max Neo. They should let us override the clearance setting. Some of us are smart enough to print a few tall items on the same bed in an arrangement that won't produce gantry collisions.
