I just bought the Form 3, and will mainly use it with Castable Wax as I am willing to print jewelry. I have an issue with filling the tank at this moment. It is very slow, I can see a couple of drops per minute - is it normal? Earlier I had an issue with it not filling at all, I had to slit the rubber band a bit and it worked. Brand new printer, resin tank, and cartridge, the print is supposed to take 1.15mL.
So check the bottom where the resin comes out it might not be open all the way just take a razorblade and gently slice it open more but not too much. Ive received some resins where the the bottom was completely sealed and i had to slice it. Also make sure you shake it good.
