Build Your Own SLA/SLS

To make prints faster, I found it obvious to tune the slicing settings:
I tested reducing the lift distance to 2mm which is enough, as it does not affect the print.
In the setup video on littlerp.com, there is a delay (1000ms) mentioned in the lift g-code (after curing befor lifting again).
I reduced this delay to 200ms, and I was wondering if this could be a reason for print fails,
or rather if this delay has any function for the curing anyhow?

I don't know for sure
but when I switched computers I forgot to add it and my print still came out,
I just use it to check on the printing before the light blinds me lol
what kinda failures are you seeing

That delay is because the timing may get off a little bit, and while it is a little generous it was added to stop the situation where the z is lifting while the image is still exposing.
