Most of my prints are anything from 5 to 20 small pieces at a time, printed at 25 micron layer height. Even when the build plate is 10mm above the resin line, it’s hard to see if pieces towards the back of the cluster of parts have successful supports. The tilt action between layers alone is around 6-7 seconds, so even with not much lasering happening, let’s say 10 seconds per layer, with the resin depth at 5mm, to get 10mm above the resin is 10s * (1mm / 0.025) * 15mm = 100 minutes.
It’s not like I have lots of problems with prints, but I get maybe 1 in 4 prints where 1 or 2 of the small objects fail because the supports failed early on. And because the pieces I print are usually different parts of a set, that means I need to do another print of the failed parts.
I’d have thought the repeatability in the z axis would be pretty good, considering it’s a stepper and you’re already presumably dealing with backlash, etc as it has to go up and down between layers anyway, but you certainly have more experience than me, so I’d trust your judgement if you really think that’s the case.
I’d quite like to try a raise on pause feature, even if it comes with a “do at your own risk” warning that it might cause a visible line. I’d rather do a little post cleanup than have to restart a print after 2+ hours that I could have started after 15 minutes if I could see that supports were failing early on.
