is there something i need to do differently after a successful print other then clean and store all materials. I have had 2 small successful prints but now on my 3rd print it will not allow me to print. There is a connection, resin and file accepted by Uniz software. do i have to do something different now to get the slash ol working again?? why will it not work after 2 prints(under 1.5 ml per print), i even tried to reprint old print and it also will not allow me to do anything.
