Is that rook print in real time ?
Bloody impressive if it is :-)
So why does it bob up and down ?

So the resin. Is that daylight resin and if so, do you have problems with it setting in the vat ?

Other than worries about that, given the cost of resin, you'd not want any to go to waste - have to say it's a very interesting looking machine.

What's the build volume ?
