RapidShape 3d printer has wait optical switch on build plate to wait for part detect vat stick when is unstick it realize build plate it goes up (this the best solution ih very hard to make and i have no time for it.

this what you don't have:

1.Delay after expose (a most important thing ) you don't have to use it i will make great thing whit it

2.pre relief lift (this slow lift after exposure is =0.3mm? 18mm/min)

3.resin shink 100% (i can nor remember 20 resin i use which has shrink more of less .

4.brim 0.2mm (See flashforge is perfekt it stick to vat like dik on pus.)best function i see it write model name this really good.

5.suports for rings 2.4mm no cone only strat vertical and straight i make video and send you or se photo(auto support i like is good) but a fast ring is not i can put this way on tree. Nedd strat vertical
